2 Advanced Linux Sound Architecture - Driver
3 ==========================================
10 To enable ALSA support you need at least to build the kernel with
11 primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS,
12 you don't have to choose any of the OSS modules.
14 Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
15 PCM supports if you want to run OSS applications with ALSA.
17 If you want to support the WaveTable functionality on cards such as
18 SB Live! then you need to enable "Sequencer support"
19 (CONFIG_SND_SEQUENCER).
21 To make ALSA debug messages more verbose, enable the "Verbose printk"
22 and "Debug" options. To check for memory leaks, turn on "Debug memory"
23 too. "Debug detection" will add checks for the detection of cards.
25 Please 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
33 This depends on your distribution, but normally you use the /dev/MAKEDEV
34 script to create the necessary device nodes. On some systems you use a
35 script named 'snddevices'.
41 The user can load modules with options. If the module supports more than
42 one card and you have more than one card of the same type then you can
43 specify multiple values for the option separated by commas.
45 Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
50 The core ALSA module. It is used by all ALSA card drivers.
51 It takes the following options which have global effects.
53 major - major number for sound driver
56 - limiting card index for auto-loading (1-8)
58 - For auto-loading more than one card, specify this
59 option together with snd-card-X aliases.
65 The PCM OSS emulation module.
66 This module takes options which change the mapping of devices.
68 dsp_map - PCM device number maps assigned to the 1st OSS device.
70 adsp_map - PCM device number maps assigned to the 2st OSS device.
73 - Don't block opening busy PCM devices. Default: 1
75 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
76 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
77 to PCM #0 of the card #0.
78 For changing the second or later card, specify the option with
79 commas, such like "dsp_map=0,1".
81 nonblock_open option is used to change the behavior of the PCM
82 regarding opening the device. When this option is non-zero,
83 opening a busy OSS PCM device won't be blocked but return
84 immediately with EAGAIN (just like O_NONBLOCK flag).
89 This module takes options which change the mapping of devices.
90 similar to those of the snd-pcm-oss module.
92 midi_map - MIDI device number maps assigned to the 1st OSS device.
94 amidi_map - MIDI device number maps assigned to the 2st OSS device.
97 Common parameters for top sound card modules
98 --------------------------------------------
100 Each of top level sound card module takes the following options.
102 index - index (slot #) of sound card
103 - Values: 0 through 31 or negative
104 - If nonnegative, assign that index number
105 - if negative, interpret as a bitmask of permissible
106 indices; the first free permitted index is assigned
108 id - card ID (identifier or name)
109 - Can be up to 15 characters long
110 - Default: the card type
111 - A directory by this name is created under /proc/asound/
112 containing information about the card
113 - This ID can be used instead of the index number in
116 - Default: enabled, for PCI and ISA PnP cards
121 Module for AdLib FM cards.
123 port - port # for OPL chip
125 This module supports multiple cards. It does not support autoprobe, so
126 the port must be specified. For actual AdLib FM cards it will be 0x388.
127 Note that this card does not have PCM support and no mixer; only FM
130 Make sure you have "sbiload" from the alsa-tools package available and,
131 after loading the module, find out the assigned ALSA sequencer port
132 number through "sbiload -l". Example output:
134 Port Client name Port name
135 64:0 OPL2 FM synth OPL2 FM Port
137 Load the std.sb and drums.sb patches also supplied by sbiload:
139 sbiload -p 64:0 std.sb drums.sb
141 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
142 instead. To have the card produce sound, use aplaymidi from alsa-utils:
144 aplaymidi -p 64:0 foo.mid

985 The model name "genric" is treated as a special case. When this
986 model is given, the driver uses the generic codec parser without
987 "codec-patch". It's sometimes good for testing and debugging.
989 If the default configuration doesn't work and one of the above
990 matches with your device, report it together with the PCI
991 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
992 ML (see the section "Links and Addresses").
994 Note 2: If you get click noises on output, try the module option
995 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
996 register value without FIFO size correction as the current
997 DMA pointer. position_fix=2 will make the driver to use
998 the position buffer instead of reading SD_LPIB register.
999 (Usually SD_LPLIB register is more accurate than the
1002 NB: If you get many "azx_get_response timeout" messages at
1003 loading, it's likely a problem of interrupts (e.g. ACPI irq
1004 routing). Try to boot with options like "pci=noacpi". Also, you
1005 can try "single_cmd=1" module option. This will switch the
1006 communication method between HDA controller and codecs to the
1007 single immediate commands instead of CORB/RIRB. Basically, the
1008 single command mode is provided only for BIOS, and you won't get
1009 unsolicited events, too. But, at least, this works independently
1010 from the irq. Remember this is a last resort, and should be
1011 avoided as much as possible...
1013 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1014 On some hardwares, you may need to add a proper probe_mask option
1015 to avoid the "azx_get_response timeout" problem above, instead.
1016 This occurs when the access to non-existing or non-working codec slot
1017 (likely a modem one) causes a stall of the communication via HD-audio
1018 bus. You can see which codec slots are probed by enabling
1019 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1020 proc files. Then limit the slots to probe by probe_mask option.
1021 For example, probe_mask=1 means to probe only the first slot, and
1022 probe_mask=4 means only the third slot.
1024 The power-management is supported.
1029 Module for RME Hammerfall DSP audio interface(s)
1031 This module supports multiple cards.
1033 Note: The firmware data can be automatically loaded via hotplug
1034 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1035 the firmware via hdsploader utility included in alsa-tools
1037 The firmware data is found in alsa-firmware package.
1039 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1040 module did formerly. It will allocate the buffers in advance
1041 when any HDSP cards are found. To make the buffer
1042 allocation sure, load snd-page-alloc module in the early
1043 stage of boot sequence. See "Early Buffer Allocation"

1385 force_ac97 - 0 or 1 (disabled by default)
1386 buffer_top - specify buffer top address
1387 use_cache - 0 or 1 (disabled by default)
1388 vaio_hack - alias buffer_top=0x25a800
1389 reset_workaround - enable AC97 RESET workaround for some laptops
1390 reset_workaround2 - enable extended AC97 RESET workaround for some
1393 This module supports one chip and autoprobe.
1395 The power-management is supported.
1397 Note: on some notebooks the buffer address cannot be detected
1398 automatically, or causes hang-up during initialization.
1399 In such a case, specify the buffer top address explicitly via
1400 the buffer_top option.
1402 Sony F250: buffer_top=0x25a800
1403 Sony F270: buffer_top=0x272800
1404 The driver supports only ac97 codec. It's possible to force
1405 to initialize/use ac97 although it's not detected. In such a
1406 case, use force_ac97=1 option - but *NO* guarantee whether it
1409 Note: The NM256 chip can be linked internally with non-AC97
1410 codecs. This driver supports only the AC97 codec, and won't work
1411 with machines with other (most likely CS423x or OPL3SAx) chips,
1412 even though the device is detected in lspci. In such a case, try
1413 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1414 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1415 and proper hardware parameters in the case without ISA PnP.
1417 Note: some laptops need a workaround for AC97 RESET. For the
1418 known hardware like Dell Latitude LS and Sony PCG-F305, this
1419 workaround is enabled automatically. For other laptops with a
1420 hard freeze, you can try reset_workaround=1 option.
1422 Note: Dell Latitude CSx laptops have another problem regarding
1423 AC97 RESET. On these laptops, reset_workaround2 option is
1424 turned on as default. This option is worth to try if the
1425 previous reset_workaround option doesn't help.
1427 Note: This driver is really crappy. It's a porting from the
1428 OSS driver, which is a result of black-magic reverse engineering.
1429 The detection of codec will fail if the driver is loaded *after*
1430 X-server as described above. You might be able to force to load
1431 the module, but it may result in hang-up. Hence, make sure that
1432 you load this module *before* X if you encounter this kind of

1809 This module supports one chip and autoprobe.
1811 Note: on some SMP motherboards like MSI 694D the interrupts might
1812 not be generated properly. In such a case, please try to
1813 set the SMP (or MPS) version on BIOS to 1.1 instead of
1814 default value 1.4. Then the interrupt number will be
1815 assigned under 15. You might also upgrade your BIOS.
1817 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1818 channels as the first PCM. On these channels, up to 4
1819 streams can be played at the same time, and the controller
1820 can perform sample rate conversion with separate rates for
1822 As default (dxs_support = 0), 48k fixed rate is chosen
1823 except for the known devices since the output is often
1824 noisy except for 48k on some mother boards due to the
1826 Please try once dxs_support=5 and if it works on other
1827 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1828 know the PCI subsystem vendor/device id's (output of
1830 If dxs_support=5 does not work, try dxs_support=4; if it
1831 doesn't work too, try dxs_support=1. (dxs_support=1 is
1832 usually for old motherboards. The correct implemented
1833 board should work with 4 or 5.) If it still doesn't
1834 work and the default setting is ok, dxs_support=3 is the
1835 right choice. If the default setting doesn't work at all,
1836 try dxs_support=2 to disable the DXS channels.
1837 In any cases, please let us know the result and the
1838 subsystem vendor/device ids. See "Links and Addresses"
1841 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1879 This module supports multiple cards.
1881 When the driver is compiled as a module and the hotplug firmware
1882 is supported, the firmware data is loaded via hotplug automatically.
1883 Install the necessary firmware files in alsa-firmware package.
1884 When no hotplug fw loader is available, you need to load the
1885 firmware via vxloader utility in alsa-tools package. To invoke
1886 vxloader automatically, add the following to /etc/modprobe.conf
1888 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1890 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1891 /etc/modules.conf, instead.)
1892 IBL size defines the interrupts period for PCM. The smaller size
1893 gives smaller latency but leads to more CPU consumption, too.
1894 The size is usually aligned to 126. As default (=0), the smallest
1895 size is chosen. The possible IBL values can be found in
1896 /proc/asound/cardX/vx-status proc file.
1898 The power-management is supported.
1903 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1905 ibl - Capture IBL size. (default = 0, minimum size)
1907 This module supports multiple cards. The module is compiled only when
1908 PCMCIA is supported on kernel.
1910 With the older 2.6.x kernel, to activate the driver via the card
1911 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1912 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1913 longer require a config file.
1915 When the driver is compiled as a module and the hotplug firmware
1916 is supported, the firmware data is loaded via hotplug automatically.
1917 Install the necessary firmware files in alsa-firmware package.
1918 When no hotplug fw loader is available, you need to load the
1919 firmware via vxloader utility in alsa-tools package.
1921 About capture IBL, see the description of snd-vx222 module.
1923 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1926 The power-management is supported.

1946 --------------------
1948 Module for Sound Core PDAudioCF sound card.
1950 The power-management is supported.
1956 The ac97_quirk option is used to enable/override the workaround for
1957 specific devices on drivers for on-board AC'97 controllers like
1958 snd-intel8x0. Some hardware have swapped output pins between Master
1959 and Headphone, or Surround (thanks to confusion of AC'97
1960 specifications from version to version :-)
1962 The driver provides the auto-detection of known problematic devices,
1963 but some might be unknown or wrongly detected. In such a case, pass
1964 the proper value with this option.
1966 The following strings are accepted:
1967 - default Don't override the default setting
1968 - none Disable the quirk
1969 - hp_only Bind Master and Headphone controls as a single control
1970 - swap_hp Swap headphone and master controls
1971 - swap_surround Swap master and surround controls
1972 - ad_sharing For AD1985, turn on OMS bit and use headphone
1973 - alc_jack For ALC65x, turn on the jack sense mode
1974 - inv_eapd Inverted EAPD implementation
1975 - mute_led Bind EAPD bit for turning on/off mute LED
1977 For backward compatibility, the corresponding integer value -1, 0,
1978 ... are accepted, too.
1980 For example, if "Master" volume control has no effect on your device
1981 but only "Headphone" does, pass ac97_quirk=hp_only module option.
1984 Configuring Non-ISAPNP Cards
1985 ============================
1987 When the kernel is configured with ISA-PnP support, the modules
1988 supporting the isapnp cards will have module options "isapnp".
1989 If this option is set, *only* the ISA-PnP devices will be probed.
1990 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1991 together with the proper i/o and irq configuration.
1993 When the kernel is configured without ISA-PnP support, isapnp option
1994 will be not built in.
1997 Module Autoloading Support
1998 ==========================
2000 The ALSA drivers can be loaded automatically on demand by defining
2001 module aliases. The string 'snd-card-%1' is requested for ALSA native
2002 devices where %i is sound card number from zero to seven.
2004 To auto-load an ALSA driver for OSS services, define the string
2005 'sound-slot-%i' where %i means the slot number for OSS, which
2006 corresponds to the card index of ALSA. Usually, define this
2007 as the same card module.
2009 An example configuration for a single emu10k1 card is like below:
2010 ----- /etc/modprobe.conf
2011 alias snd-card-0 snd-emu10k1
2012 alias sound-slot-0 snd-emu10k1
2013 ----- /etc/modprobe.conf
2015 The available number of auto-loaded sound cards depends on the module
2016 option "cards_limit" of snd module. As default it's set to 1.
2017 To enable the auto-loading of multiple cards, specify the number of
2018 sound cards in that option.
2020 When multiple cards are available, it'd better to specify the index
2021 number for each card via module option, too, so that the order of
2022 cards is kept consistent.
2024 An example configuration for two sound cards is like below:
2026 ----- /etc/modprobe.conf
2028 options snd cards_limit=2
2029 alias snd-card-0 snd-interwave
2030 alias snd-card-1 snd-ens1371
2031 options snd-interwave index=0
2032 options snd-ens1371 index=1
2034 alias sound-slot-0 snd-interwave
2035 alias sound-slot-1 snd-ens1371
2036 ----- /etc/modprobe.conf
2038 In this example, the interwave card is always loaded as the first card
2039 (index 0) and ens1371 as the second (index 1).
2042 ALSA PCM devices to OSS devices mapping
2043 =======================================
2045 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2046 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2047 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2048 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2049 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2050 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2051 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2052 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2053 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2055 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2056 sound card number and second means device number. The ALSA devices
2057 have either 'c' or 'p' suffix indicating the direction, capture and
2058 playback, respectively.
2060 Please note that the device mapping above may be varied via the module
2061 options of snd-pcm-oss module.
2064 Proc interfaces (/proc/asound)
2065 ==============================
2067 /proc/asound/card#/pcm#[cp]/oss
2068 -------------------------------
2069 String "erase" - erase all additional informations about OSS applications
2070 String "<app_name> <fragments> <fragment_size> [<options>]"
2072 <app_name> - name of application with (higher priority) or without path
2073 <fragments> - number of fragments or zero if auto
2074 <fragment_size> - size of fragment in bytes or zero if auto
2075 <options> - optional parameters
2076 - disable the application tries to open a pcm device for
2077 this channel but does not want to use it.
2078 (Cause a bug or mmap needs)
2079 It's good for Quake etc...
2080 - direct don't use plugins
2081 - block force block mode (rvplayer)
2082 - non-block force non-block mode
2083 - whole-frag write only whole fragments (optimization affecting
2085 - no-silence do not fill silence ahead to avoid clicks
2086 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2087 instead of filled blocks
2089 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2090 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2091 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2094 Early Buffer Allocation
2095 =======================
2097 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2098 sometimes it's too late to find such spaces when the driver module is
2099 actually loaded due to memory fragmentation. You can pre-allocate the
2100 PCM buffers by loading snd-page-alloc module and write commands to its
2101 proc file in prior, for example, in the early boot stage like
2102 /etc/init.d/*.local scripts.
2104 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2105 usage of page allocation. In writing, you can send the following
2106 commands to the snd-page-alloc driver:
2108 - add VENDOR DEVICE MASK SIZE BUFFERS
2110 VENDOR and DEVICE are PCI vendor and device IDs. They take
2111 integer numbers (0x prefix is needed for the hex).
2112 MASK is the PCI DMA mask. Pass 0 if not restricted.
2113 SIZE is the size of each buffer to allocate. You can pass
2114 k and m suffix for KB and MB. The max number is 16MB.
2115 BUFFERS is the number of buffers to allocate. It must be greater
2116 than 0. The max number is 4.
2120 This will erase the all pre-allocated buffers which are not in
