1 2 Advanced Linux Sound Architecture - Driver 3 ========================================== 4 Configuration guide 5 6 7Kernel Configuration 8==================== 9 10To enable ALSA support you need at least to build the kernel with 11primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, 12you don't have to choose any of the OSS modules. 13 14Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and 15PCM supports if you want to run OSS applications with ALSA. 16 17If you want to support the WaveTable functionality on cards such as 18SB Live! then you need to enable "Sequencer support" 19(CONFIG_SND_SEQUENCER). 20 21To make ALSA debug messages more verbose, enable the "Verbose printk" 22and "Debug" options. To check for memory leaks, turn on "Debug memory" 23too. "Debug detection" will add checks for the detection of cards. 24 25Please note that all the ALSA ISA drivers support the Linux isapnp API 26(if the card supports ISA PnP). You don't need to configure the cards 27using isapnptools. 28 29 30Creating ALSA devices 31===================== 32 33This depends on your distribution, but normally you use the /dev/MAKEDEV 34script to create the necessary device nodes. On some systems you use a 35script named 'snddevices'. 36 37 38Module parameters 39================= 40 41The user can load modules with options. If the module supports more than 42one card and you have more than one card of the same type then you can 43specify multiple values for the option separated by commas. 44 45Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed. 46 47 Module snd 48 ---------- 49 50 The core ALSA module. It is used by all ALSA card drivers. 51 It takes the following options which have global effects. 52 53 major - major number for sound driver 54 - Default: 116 55 cards_limit 56 - limiting card index for auto-loading (1-8) 57 - Default: 1 58 - For auto-loading more than one card, specify this 59 option together with snd-card-X aliases. 60 slots - Reserve the slot index for the given driver. 61 This option takes multiple strings. 62 See "Module Autoloading Support" section for details. 63 debug - Specifies the debug message level 64 (0 = disable debug prints, 1 = normal debug messages, 65 2 = verbose debug messages) 66 This option appears only when CONFIG_SND_DEBUG=y. 67 This option can be dynamically changed via sysfs 68 /sys/modules/snd/parameters/debug file. 69 70 Module snd-pcm-oss 71 ------------------ 72 73 The PCM OSS emulation module. 74 This module takes options which change the mapping of devices. 75 76 dsp_map - PCM device number maps assigned to the 1st OSS device. 77 - Default: 0 78 adsp_map - PCM device number maps assigned to the 2st OSS device. 79 - Default: 1 80 nonblock_open 81 - Don't block opening busy PCM devices. Default: 1 82 83 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of 84 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped 85 to PCM #0 of the card #0. 86 For changing the second or later card, specify the option with 87 commas, such like "dsp_map=0,1". 88 89 nonblock_open option is used to change the behavior of the PCM 90 regarding opening the device. When this option is non-zero, 91 opening a busy OSS PCM device won't be blocked but return 92 immediately with EAGAIN (just like O_NONBLOCK flag). 93 94 Module snd-rawmidi 95 ------------------ 96 97 This module takes options which change the mapping of devices. 98 similar to those of the snd-pcm-oss module. 99 100 midi_map - MIDI device number maps assigned to the 1st OSS device. 101 - Default: 0 102 amidi_map - MIDI device number maps assigned to the 2st OSS device. 103 - Default: 1 104 105 Common parameters for top sound card modules 106 -------------------------------------------- 107 108 Each of top level sound card module takes the following options. 109 110 index - index (slot #) of sound card 111 - Values: 0 through 31 or negative 112 - If nonnegative, assign that index number 113 - if negative, interpret as a bitmask of permissible 114 indices; the first free permitted index is assigned 115 - Default: -1 116 id - card ID (identifier or name) 117 - Can be up to 15 characters long 118 - Default: the card type 119 - A directory by this name is created under /proc/asound/ 120 containing information about the card 121 - This ID can be used instead of the index number in 122 identifying the card 123 enable - enable card 124 - Default: enabled, for PCI and ISA PnP cards 125 126 Module snd-adlib 127 ---------------- 128 129 Module for AdLib FM cards. 130 131 port - port # for OPL chip 132 133 This module supports multiple cards. It does not support autoprobe, so 134 the port must be specified. For actual AdLib FM cards it will be 0x388. 135 Note that this card does not have PCM support and no mixer; only FM 136 synthesis. 137 138 Make sure you have "sbiload" from the alsa-tools package available and, 139 after loading the module, find out the assigned ALSA sequencer port 140 number through "sbiload -l". Example output: 141 142 Port Client name Port name 143 64:0 OPL2 FM synth OPL2 FM Port 144 145 Load the std.sb and drums.sb patches also supplied by sbiload: 146 147 sbiload -p 64:0 std.sb drums.sb 148 149 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 150 instead. To have the card produce sound, use aplaymidi from alsa-utils: 151 152 aplaymidi -p 64:0 foo.mid 153 154 Module snd-ad1816a 155 ------------------ 156 157 Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips. 158 159 clockfreq - Clock frequency for AD1816A chip (default = 0, 33000Hz) 160 161 This module supports multiple cards, autoprobe and PnP. 162 163 Module snd-ad1848 164 ----------------- 165 166 Module for sound cards based on AD1848/AD1847/CS4248 ISA chips. 167 168 port - port # for AD1848 chip 169 irq - IRQ # for AD1848 chip 170 dma1 - DMA # for AD1848 chip (0,1,3) 171 172 This module supports multiple cards.

force the model name 863 position_fix - Fix DMA pointer 864 -1 = system default: choose appropriate one per controller 865 hardware 866 0 = auto: falls back to LPIB when POSBUF doesn't work 867 1 = use LPIB 868 2 = POSBUF: use position buffer 869 3 = VIACOMBO: VIA-specific workaround for capture 870 4 = COMBO: use LPIB for playback, auto for capture stream 871 probe_mask - Bitmask to probe codecs (default = -1, meaning all slots) 872 When the bit 8 (0x100) is set, the lower 8 bits are used 873 as the "fixed" codec slots; i.e. the driver probes the 874 slots regardless what hardware reports back 875 probe_only - Only probing and no codec initialization (default=off); 876 Useful to check the initial codec status for debugging 877 bdl_pos_adj - Specifies the DMA IRQ timing delay in samples. 878 Passing -1 will make the driver to choose the appropriate 879 value based on the controller chip. 880 patch - Specifies the early "patch" files to modify the HD-audio 881 setup before initializing the codecs. This option is 882 available only when CONFIG_SND_HDA_PATCH_LOADER=y is set. 883 See HD-Audio.txt for details. 884 beep_mode - Selects the beep registration mode (0=off, 1=on); default 885 value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig. 886 887 [Single (global) options] 888 single_cmd - Use single immediate commands to communicate with 889 codecs (for debugging only) 890 enable_msi - Enable Message Signaled Interrupt (MSI) (default = off) 891 power_save - Automatic power-saving timeout (in second, 0 = 892 disable) 893 power_save_controller - Reset HD-audio controller in power-saving mode 894 (default = on) 895 align_buffer_size - Force rounding of buffer/period sizes to multiples 896 of 128 bytes. This is more efficient in terms of memory 897 access but isn't required by the HDA spec and prevents 898 users from specifying exact period/buffer sizes. 899 (default = on) 900 snoop - Enable/disable snooping (default = on) 901 902 This module supports multiple cards and autoprobe. 903 904 See Documentation/sound/alsa/HD-Audio.txt for more details about 905 HD-audio driver. 906 907 Each codec may have a model table for different configurations. 908 If your machine isn't listed there, the default (usually minimal) 909 configuration is set up. You can pass "model=<name>" option to 910 specify a certain model in such a case. There are different 911 models depending on the codec chip. The list of available models 912 is found in HD-Audio-Models.txt 913 914 The model name "generic" is treated as a special case. When this 915 model is given, the driver uses the generic codec parser without 916 "codec-patch". It's sometimes good for testing and debugging. 917 918 If the default configuration doesn't work and one of the above 919 matches with your device, report it together with alsa-info.sh 920 output (with --no-upload option) to kernel bugzilla or alsa-devel 921 ML (see the section "Links and Addresses"). 922 923 power_save and power_save_controller options are for power-saving 924 mode. See powersave.txt for details. 925 926 Note 2: If you get click noises on output, try the module option 927 position_fix=1 or 2. position_fix=1 will use the SD_LPIB 928 register value without FIFO size correction as the current 929 DMA pointer. position_fix=2 will make the driver to use 930 the position buffer instead of reading SD_LPIB register. 931 (Usually SD_LPIB register is more accurate than the 932 position buffer.) 933 934 position_fix=3 is specific to VIA devices. The position 935 of the capture stream is checked from both LPIB and POSBUF 936 values. position_fix=4 is a combination mode, using LPIB 937 for playback and POSBUF for capture. 938 939 NB: If you get many "azx_get_response timeout" messages at 940 loading, it's likely a problem of interrupts (e.g. ACPI irq 941 routing). Try to boot with options like "pci=noacpi". Also, you 942 can try "single_cmd=1" module option. This will switch the 943 communication method between HDA controller and codecs to the 944 single immediate commands instead of CORB/RIRB. Basically, the 945 single command mode is provided only for BIOS, and you won't get 946 unsolicited events, too. But, at least, this works independently 947 from the irq. Remember this is a last resort, and should be 948 avoided as much as possible... 949 950 MORE NOTES ON "azx_get_response timeout" PROBLEMS: 951 On some hardware, you may need to add a proper probe_mask option 952 to avoid the "azx_get_response timeout" problem above, instead. 953 This occurs when the access to non-existing or non-working codec slot 954 (likely a modem one) causes a stall of the communication via HD-audio 955 bus. You can see which codec slots are probed by enabling 956 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec 957 proc files. Then limit the slots to probe by probe_mask option. 958 For example, probe_mask=1 means to probe only the first slot, and 959 probe_mask=4 means only the third slot. 960 961 The power-management is supported. 962 963 Module snd-hdsp 964 --------------- 965 966 Module for RME Hammerfall DSP audio interface(s) 967 968 This module supports multiple cards. 969 970 Note: The firmware data can be automatically loaded via hotplug 971 when CONFIG_FW_LOADER is set. Otherwise, you need to load 972 the firmware via hdsploader utility included in alsa-tools 973 package. 974 The firmware data is found in alsa-firmware package. 975 976 Note: snd-page-alloc module does the job which snd-hammerfall-mem 977 module did formerly. It will allocate the buffers in advance 978 when any HDSP cards are found. To make the buffer 979 allocation sure, load snd-page-alloc module in the early 980 stage of boot sequence.

Note that it has been discontinued, but the 1371 Voyetra Turtle Beach knowledge base entry for it is still available 1372 at 1373 http://www.turtlebeach.com 1374 1375 Module snd-msnd-pinnacle 1376 ------------------------ 1377 1378 Module for Turtle Beach MultiSound Pinnacle/Fiji soundcards. 1379 1380 io - Port # for pinnacle/fiji card 1381 irq - IRQ # for pinnalce/fiji card 1382 mem - Memory address (0xb0000, 0xc8000, 0xd0000, 0xd8000, 1383 0xe0000 or 0xe8000) 1384 write_ndelay - enable write ndelay (default = 1) 1385 calibrate_signal - calibrate signal (default = 0) 1386 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1387 1388 The driver requires firmware files "turtlebeach/pndspini.bin" and 1389 "turtlebeach/pndsperm.bin" in the proper firmware directory. 1390 1391 Module snd-mtpav 1392 ---------------- 1393 1394 Module for MOTU MidiTimePiece AV multiport MIDI (on the parallel 1395 port). 1396 1397 port - I/O port # for MTPAV (0x378,0x278, default=0x378) 1398 irq - IRQ # for MTPAV (7,5, default=7) 1399 hwports - number of supported hardware ports, default=8. 1400 1401 Module supports only 1 card. This module has no enable option. 1402 1403 Module snd-mts64 1404 ---------------- 1405 1406 Module for Ego Systems (ESI) Miditerminal 4140 1407 1408 This module supports multiple devices. 1409 Requires parport (CONFIG_PARPORT). 1410 1411 Module snd-nm256 1412 ---------------- 1413 1414 Module for NeoMagic NM256AV/ZX chips 1415 1416 playback_bufsize - max playback frame size in kB (4-128kB) 1417 capture_bufsize - max capture frame size in kB (4-128kB) 1418 force_ac97 - 0 or 1 (disabled by default) 1419 buffer_top - specify buffer top address 1420 use_cache - 0 or 1 (disabled by default) 1421 vaio_hack - alias buffer_top=0x25a800 1422 reset_workaround - enable AC97 RESET workaround for some laptops 1423 reset_workaround2 - enable extended AC97 RESET workaround for some 1424 other laptops 1425 1426 This module supports one chip and autoprobe. 1427 1428 The power-management is supported. 1429 1430 Note: on some notebooks the buffer address cannot be detected 1431 automatically, or causes hang-up during initialization. 1432 In such a case, specify the buffer top address explicitly via 1433 the buffer_top option. 1434 For example, 1435 Sony F250: buffer_top=0x25a800 1436 Sony F270: buffer_top=0x272800 1437 The driver supports only ac97 codec. It's possible to force 1438 to initialize/use ac97 although it's not detected. In such a 1439 case, use force_ac97=1 option - but *NO* guarantee whether it 1440 works! 1441 1442 Note: The NM256 chip can be linked internally with non-AC97 1443 codecs. This driver supports only the AC97 codec, and won't work 1444 with machines with other (most likely CS423x or OPL3SAx) chips, 1445 even though the device is detected in lspci. In such a case, try 1446 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP 1447 but some doesn't have ISA PnP. You'll need to specify isapnp=0 1448 and proper hardware parameters in the case without ISA PnP. 1449 1450 Note: some laptops need a workaround for AC97 RESET. For the 1451 known hardware like Dell Latitude LS and Sony PCG-F305, this 1452 workaround is enabled automatically. For other laptops with a 1453 hard freeze, you can try reset_workaround=1 option. 1454 1455 Note: Dell Latitude CSx laptops have another problem regarding 1456 AC97 RESET. On these laptops, reset_workaround2 option is 1457 turned on as default. This option is worth to try if the 1458 previous reset_workaround option doesn't help. 1459 1460 Note: This driver is really crappy. It's a porting from the 1461 OSS driver, which is a result of black-magic reverse engineering. 1462 The detection of codec will fail if the driver is loaded *after* 1463 X-server as described above. You might be able to force to load 1464 the module, but it may result in hang-up. Hence, make sure that 1465 you load this module *before* X if you encounter this kind of 1466 problem. 1467 1468 Module snd-opl3sa2 1469 ------------------ 1470 1471 Module for Yamaha OPL3-SA2/SA3 sound cards. 1472 1473 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1474 1475 with isapnp=0, the following options are available: 1476 1477 port - control port # for OPL3-SA chip (0x370) 1478 sb_port - SB port # for OPL3-SA chip (0x220,0x240) 1479 wss_port - WSS port # for OPL3-SA chip (0x530,0xe80,0xf40,0x604) 1480 midi_port - port # for MPU-401 UART (0x300,0x330), -1 = disable 1481 fm_port - FM port # for OPL3-SA chip (0x388), -1 = disable 1482 irq - IRQ # for OPL3-SA chip (5,7,9,10) 1483 dma1 - first DMA # for Yamaha OPL3-SA chip (0,1,3) 1484 dma2 - second DMA # for Yamaha OPL3-SA chip (0,1,3), -1 = disable 1485 1486 This module supports multiple cards and ISA PnP.

This happens on some 1921 buggy USB device or the controller. 1922 1923 Module snd-usb-caiaq 1924 -------------------- 1925 1926 Module for caiaq UB audio interfaces, 1927 * Native Instruments RigKontrol2 1928 * Native Instruments Kore Controller 1929 * Native Instruments Audio Kontrol 1 1930 * Native Instruments Audio 8 DJ 1931 1932 This module supports multiple devices, autoprobe and hotplugging. 1933 1934 Module snd-usb-usx2y 1935 -------------------- 1936 1937 Module for Tascam USB US-122, US-224 and US-428 devices. 1938 1939 This module supports multiple devices, autoprobe and hotplugging. 1940 1941 Note: you need to load the firmware via usx2yloader utility included 1942 in alsa-tools and alsa-firmware packages. 1943 1944 Module snd-via82xx 1945 ------------------ 1946 1947 Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 1948 8233A, 8233C, 8235, 8237 (south) bridge. 1949 1950 mpu_port - 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup 1951 [VIA686A/686B only] 1952 joystick - Enable joystick (default off) [VIA686A/686B only] 1953 ac97_clock - AC'97 codec clock base (default 48000Hz) 1954 dxs_support - support DXS channels, 1955 0 = auto (default), 1 = enable, 2 = disable, 1956 3 = 48k only, 4 = no VRA, 5 = enable any sample 1957 rate and different sample rates on different 1958 channels 1959 [VIA8233/C, 8235, 8237 only] 1960 ac97_quirk - AC'97 workaround for strange hardware 1961 See "AC97 Quirk Option" section below. 1962 1963 This module supports one chip and autoprobe. 1964 1965 Note: on some SMP motherboards like MSI 694D the interrupts might 1966 not be generated properly. In such a case, please try to 1967 set the SMP (or MPS) version on BIOS to 1.1 instead of 1968 default value 1.4. Then the interrupt number will be 1969 assigned under 15. You might also upgrade your BIOS. 1970 1971 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) 1972 channels as the first PCM. On these channels, up to 4 1973 streams can be played at the same time, and the controller 1974 can perform sample rate conversion with separate rates for 1975 each channel. 1976 As default (dxs_support = 0), 48k fixed rate is chosen 1977 except for the known devices since the output is often 1978 noisy except for 48k on some mother boards due to the 1979 bug of BIOS. 1980 Please try once dxs_support=5 and if it works on other 1981 sample rates (e.g. 44.1kHz of mp3 playback), please let us 1982 know the PCI subsystem vendor/device id's (output of 1983 "lspci -nv"). 1984 If dxs_support=5 does not work, try dxs_support=4; if it 1985 doesn't work too, try dxs_support=1. (dxs_support=1 is 1986 usually for old motherboards. The correct implemented 1987 board should work with 4 or 5.) If it still doesn't 1988 work and the default setting is ok, dxs_support=3 is the 1989 right choice. If the default setting doesn't work at all, 1990 try dxs_support=2 to disable the DXS channels. 1991 In any cases, please let us know the result and the 1992 subsystem vendor/device ids. See "Links and Addresses" 1993 below. 1994 1995 Note: for the MPU401 on VIA823x, use snd-mpu401 driver 1996 additionally. The mpu_port option is for VIA686 chips only. 1997 1998 The power-management is supported. 1999 2000 Module snd-via82xx-modem 2001 ------------------------ 2002 2003 Module for VIA82xx AC97 modem 2004 2005 ac97_clock - AC'97 codec clock base (default 48000Hz) 2006 2007 This module supports one card and autoprobe. 2008 2009 Note: The default index value of this module is -2, i.e. the first 2010 slot is excluded. 2011 2012 The power-management is supported. 2013 2014 Module snd-virmidi 2015 ------------------ 2016 2017 Module for virtual rawmidi devices. 2018 This module creates virtual rawmidi devices which communicate 2019 to the corresponding ALSA sequencer ports. 2020 2021 midi_devs - MIDI devices # (1-4, default=4) 2022 2023 This module supports multiple cards. 2024 2025 Module snd-virtuoso 2026 ------------------- 2027 2028 Module for sound cards based on the Asus AV66/AV100/AV200 chips, 2029 i.e., Xonar D1, DX, D2, D2X, DS, DSX, Essence ST (Deluxe), 2030 Essence STX (II), HDAV1.3 (Deluxe), and HDAV1.3 Slim. 2031 2032 This module supports autoprobe and multiple cards. 2033 2034 Module snd-vx222 2035 ---------------- 2036 2037 Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. 2038 2039 mic - Enable Microphone on V222 Mic (NYI) 2040 ibl - Capture IBL size. (default = 0, minimum size) 2041 2042 This module supports multiple cards. 2043 2044 When the driver is compiled as a module and the hotplug firmware 2045 is supported, the firmware data is loaded via hotplug automatically. 2046 Install the necessary firmware files in alsa-firmware package. 2047 When no hotplug fw loader is available, you need to load the 2048 firmware via vxloader utility in alsa-tools package. To invoke 2049 vxloader automatically, add the following to /etc/modprobe.d/alsa.conf 2050 2051 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader 2052 2053 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to 2054 /etc/modules.conf, instead.) 2055 IBL size defines the interrupts period for PCM. The smaller size 2056 gives smaller latency but leads to more CPU consumption, too. 2057 The size is usually aligned to 126. As default (=0), the smallest 2058 size is chosen. The possible IBL values can be found in 2059 /proc/asound/cardX/vx-status proc file. 2060 2061 The power-management is supported. 2062 2063 Module snd-vxpocket 2064 ------------------- 2065 2066 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. 2067 2068 ibl - Capture IBL size. (default = 0, minimum size) 2069 2070 This module supports multiple cards. The module is compiled only when 2071 PCMCIA is supported on kernel. 2072 2073 With the older 2.6.x kernel, to activate the driver via the card 2074 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the 2075 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no 2076 longer require a config file. 2077 2078 When the driver is compiled as a module and the hotplug firmware 2079 is supported, the firmware data is loaded via hotplug automatically. 2080 Install the necessary firmware files in alsa-firmware package. 2081 When no hotplug fw loader is available, you need to load the 2082 firmware via vxloader utility in alsa-tools package. 2083 2084 About capture IBL, see the description of snd-vx222 module. 2085 2086 Note: snd-vxp440 driver is merged to snd-vxpocket driver since 2087 ALSA 1.0.10. 2088 2089 The power-management is supported. 2090 2091 Module snd-ymfpci 2092 ----------------- 2093 2094 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x). 2095 2096 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default, 2097 1 (auto-detect for YMF744/754 only) 2098 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default 2099 1 (auto-detect for YMF744/754 only) 2100 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default, 2101 1 (auto-detect) 2102 rear_switch - enable shared rear/line-in switch (bool) 2103 2104 This module supports autoprobe and multiple chips. 2105 2106 The power-management is supported. 2107 2108 Module snd-pdaudiocf 2109 -------------------- 2110 2111 Module for Sound Core PDAudioCF sound card. 2112 2113 The power-management is supported. 2114 2115 2116AC97 Quirk Option 2117================= 2118 2119The ac97_quirk option is used to enable/override the workaround for 2120specific devices on drivers for on-board AC'97 controllers like 2121snd-intel8x0. Some hardware have swapped output pins between Master 2122and Headphone, or Surround (thanks to confusion of AC'97 2123specifications from version to version :-) 2124 2125The driver provides the auto-detection of known problematic devices, 2126but some might be unknown or wrongly detected. In such a case, pass 2127the proper value with this option. 2128 2129The following strings are accepted: 2130 - default Don't override the default setting 2131 - none Disable the quirk 2132 - hp_only Bind Master and Headphone controls as a single control 2133 - swap_hp Swap headphone and master controls 2134 - swap_surround Swap master and surround controls 2135 - ad_sharing For AD1985, turn on OMS bit and use headphone 2136 - alc_jack For ALC65x, turn on the jack sense mode 2137 - inv_eapd Inverted EAPD implementation 2138 - mute_led Bind EAPD bit for turning on/off mute LED 2139 2140For backward compatibility, the corresponding integer value -1, 0, 2141... are accepted, too. 2142 2143For example, if "Master" volume control has no effect on your device 2144but only "Headphone" does, pass ac97_quirk=hp_only module option. 2145 2146 2147Configuring Non-ISAPNP Cards 2148============================ 2149 2150When the kernel is configured with ISA-PnP support, the modules 2151supporting the isapnp cards will have module options "isapnp". 2152If this option is set, *only* the ISA-PnP devices will be probed. 2153For probing the non ISA-PnP cards, you have to pass "isapnp=0" option 2154together with the proper i/o and irq configuration. 2155 2156When the kernel is configured without ISA-PnP support, isapnp option 2157will be not built in. 2158 2159 2160Module Autoloading Support 2161========================== 2162 2163The ALSA drivers can be loaded automatically on demand by defining 2164module aliases. The string 'snd-card-%1' is requested for ALSA native 2165devices where %i is sound card number from zero to seven. 2166 2167To auto-load an ALSA driver for OSS services, define the string 2168'sound-slot-%i' where %i means the slot number for OSS, which 2169corresponds to the card index of ALSA. Usually, define this 2170as the same card module. 2171 2172An example configuration for a single emu10k1 card is like below: 2173----- /etc/modprobe.d/alsa.conf 2174alias snd-card-0 snd-emu10k1 2175alias sound-slot-0 snd-emu10k1 2176----- /etc/modprobe.d/alsa.conf 2177 2178The available number of auto-loaded sound cards depends on the module 2179option "cards_limit" of snd module. As default it's set to 1. 2180To enable the auto-loading of multiple cards, specify the number of 2181sound cards in that option. 2182 2183When multiple cards are available, it'd better to specify the index 2184number for each card via module option, too, so that the order of 2185cards is kept consistent. 2186 2187An example configuration for two sound cards is like below: 2188 2189----- /etc/modprobe.d/alsa.conf 2190# ALSA portion 2191options snd cards_limit=2 2192alias snd-card-0 snd-interwave 2193alias snd-card-1 snd-ens1371 2194options snd-interwave index=0 2195options snd-ens1371 index=1 2196# OSS/Free portion 2197alias sound-slot-0 snd-interwave 2198alias sound-slot-1 snd-ens1371 2199----- /etc/modprobe.d/alsa.conf 2200 2201In this example, the interwave card is always loaded as the first card 2202(index 0) and ens1371 as the second (index 1). 2203 2204Alternative (and new) way to fixate the slot assignment is to use 2205"slots" option of snd module. In the case above, specify like the 2206following: 2207 2208options snd slots=snd-interwave,snd-ens1371 2209 2210Then, the first slot (#0) is reserved for snd-interwave driver, and 2211the second (#1) for snd-ens1371. You can omit index option in each 2212driver if slots option is used (although you can still have them at 2213the same time as long as they don't conflict). 2214 2215The slots option is especially useful for avoiding the possible 2216hot-plugging and the resultant slot conflict. For example, in the 2217case above again, the first two slots are already reserved. If any 2218other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2219snd-ens1371, it will be assigned to the third or later slot. 2220 2221When a module name is given with '!', the slot will be given for any 2222modules but that name. For example, "slots=!snd-pcsp" will reserve 2223the first slot for any modules but snd-pcsp. 2224 2225 2226ALSA PCM devices to OSS devices mapping 2227======================================= 2228 2229/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2230/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2231/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2232/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2233/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2234/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2235/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2236/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2237/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2238 2239The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means 2240sound card number and second means device number. The ALSA devices 2241have either 'c' or 'p' suffix indicating the direction, capture and 2242playback, respectively. 2243 2244Please note that the device mapping above may be varied via the module 2245options of snd-pcm-oss module. 2246 2247 2248Proc interfaces (/proc/asound) 2249============================== 2250 2251/proc/asound/card#/pcm#[cp]/oss 2252------------------------------- 2253 String "erase" - erase all additional information about OSS applications 2254 String "<app_name> <fragments> <fragment_size> [<options>]" 2255 2256 <app_name> - name of application with (higher priority) or without path 2257 <fragments> - number of fragments or zero if auto 2258 <fragment_size> - size of fragment in bytes or zero if auto 2259 <options> - optional parameters 2260 - disable the application tries to open a pcm device for 2261 this channel but does not want to use it. 2262 (Cause a bug or mmap needs) 2263 It's good for Quake etc... 2264 - direct don't use plugins 2265 - block force block mode (rvplayer) 2266 - non-block force non-block mode 2267 - whole-frag write only whole fragments (optimization affecting 2268 playback only) 2269 - no-silence do not fill silence ahead to avoid clicks 2270 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl 2271 instead of filled blocks 2272 2273 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss 2274 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss 2275 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss 2276 2277 2278Early Buffer Allocation 2279======================= 2280 2281Some drivers (e.g. hdsp) require the large contiguous buffers, and 2282sometimes it's too late to find such spaces when the driver module is 2283actually loaded due to memory fragmentation. You can pre-allocate the 2284PCM buffers by loading snd-page-alloc module and write commands to its 2285proc file in prior, for example, in the early boot stage like 2286/etc/init.d/*.local scripts. 2287 2288Reading the proc file /proc/drivers/snd-page-alloc shows the current 2289usage of page allocation. In writing, you can send the following 2290commands to the snd-page-alloc driver: 2291 2292 - add VENDOR DEVICE MASK SIZE BUFFERS 2293 2294 VENDOR and DEVICE are PCI vendor and device IDs. They take 2295 integer numbers (0x prefix is needed for the hex). 2296 MASK is the PCI DMA mask. Pass 0 if not restricted. 2297 SIZE is the size of each buffer to allocate. You can pass 2298 k and m suffix for KB and MB. The max number is 16MB. 2299 BUFFERS is the number of buffers to allocate. It must be greater 2300 than 0. The max number is 4. 2301 2302 - erase 2303 2304 This will erase the all pre-allocated buffers which are not in 2305 use. 2306 2307 2308Links and Addresses 2309=================== 2310 2311 ALSA project homepage 2312 http://www.alsa-project.org 2313 2314 Kernel Bugzilla 2315 http://bugzilla.kernel.org/ 2316 2317 ALSA Developers ML 2318 mailto:alsa-devel@alsa-project.org 2319 2320 alsa-info.sh script 2321 http://www.alsa-project.org/alsa-info.sh 2322
