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

962 The model name "genric" is treated as a special case. When this
963 model is given, the driver uses the generic codec parser without
964 "codec-patch". It's sometimes good for testing and debugging.
966 If the default configuration doesn't work and one of the above
967 matches with your device, report it together with the PCI
968 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
969 ML (see the section "Links and Addresses").
971 Note 2: If you get click noises on output, try the module option
972 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
973 register value without FIFO size correction as the current
974 DMA pointer. position_fix=2 will make the driver to use
975 the position buffer instead of reading SD_LPIB register.
976 (Usually SD_LPLIB register is more accurate than the
979 NB: If you get many "azx_get_response timeout" messages at
980 loading, it's likely a problem of interrupts (e.g. ACPI irq
981 routing). Try to boot with options like "pci=noacpi". Also, you
982 can try "single_cmd=1" module option. This will switch the
983 communication method between HDA controller and codecs to the
984 single immediate commands instead of CORB/RIRB. Basically, the
985 single command mode is provided only for BIOS, and you won't get
986 unsolicited events, too. But, at least, this works independently
987 from the irq. Remember this is a last resort, and should be
988 avoided as much as possible...
990 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
991 On some hardwares, you may need to add a proper probe_mask option
992 to avoid the "azx_get_response timeout" problem above, instead.
993 This occurs when the access to non-existing or non-working codec slot
994 (likely a modem one) causes a stall of the communication via HD-audio
995 bus. You can see which codec slots are probed by enabling
996 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
997 proc files. Then limit the slots to probe by probe_mask option.
998 For example, probe_mask=1 means to probe only the first slot, and
999 probe_mask=4 means only the third slot.
1001 The power-management is supported.
1006 Module for RME Hammerfall DSP audio interface(s)
1008 This module supports multiple cards.
1010 Note: The firmware data can be automatically loaded via hotplug

1016 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1017 module did formerly. It will allocate the buffers in advance
1018 when any HDSP cards are found. To make the buffer
1019 allocation sure, load snd-page-alloc module in the early
1020 stage of boot sequence. See "Early Buffer Allocation"

1388 with machines with other (most likely CS423x or OPL3SAx) chips,
1389 even though the device is detected in lspci. In such a case, try
1390 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1391 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1392 and proper hardware parameters in the case without ISA PnP.
1394 Note: some laptops need a workaround for AC97 RESET. For the
1395 known hardware like Dell Latitude LS and Sony PCG-F305, this
1396 workaround is enabled automatically. For other laptops with a
1397 hard freeze, you can try reset_workaround=1 option.
1399 Note: Dell Latitude CSx laptops have another problem regarding
1400 AC97 RESET. On these laptops, reset_workaround2 option is
1401 turned on as default. This option is worth to try if the
1402 previous reset_workaround option doesn't help.
1404 Note: This driver is really crappy. It's a porting from the
1405 OSS driver, which is a result of black-magic reverse engineering.
1406 The detection of codec will fail if the driver is loaded *after*
1407 X-server as described above. You might be able to force to load
1408 the module, but it may result in hang-up. Hence, make sure that
1409 you load this module *before* X if you encounter this kind of

1783 ac97_quirk - AC'97 workaround for strange hardware
1784 See "AC97 Quirk Option" section below.
1786 This module supports one chip and autoprobe.
1788 Note: on some SMP motherboards like MSI 694D the interrupts might
1789 not be generated properly. In such a case, please try to
1790 set the SMP (or MPS) version on BIOS to 1.1 instead of
1791 default value 1.4. Then the interrupt number will be
1792 assigned under 15. You might also upgrade your BIOS.
1794 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1795 channels as the first PCM. On these channels, up to 4
1796 streams can be played at the same time, and the controller
1797 can perform sample rate conversion with separate rates for
1799 As default (dxs_support = 0), 48k fixed rate is chosen
1800 except for the known devices since the output is often
1801 noisy except for 48k on some mother boards due to the
1803 Please try once dxs_support=5 and if it works on other
1804 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1805 know the PCI subsystem vendor/device id's (output of
1807 If dxs_support=5 does not work, try dxs_support=4; if it
1808 doesn't work too, try dxs_support=1. (dxs_support=1 is
1809 usually for old motherboards. The correct implemented
1810 board should work with 4 or 5.) If it still doesn't
1811 work and the default setting is ok, dxs_support=3 is the
1812 right choice. If the default setting doesn't work at all,
1813 try dxs_support=2 to disable the DXS channels.
1814 In any cases, please let us know the result and the
1815 subsystem vendor/device ids. See "Links and Addresses"
1818 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1853 mic - Enable Microphone on V222 Mic (NYI)
1854 ibl - Capture IBL size. (default = 0, minimum size)
1856 This module supports multiple cards.
1858 When the driver is compiled as a module and the hotplug firmware
1859 is supported, the firmware data is loaded via hotplug automatically.
1860 Install the necessary firmware files in alsa-firmware package.
1861 When no hotplug fw loader is available, you need to load the
1862 firmware via vxloader utility in alsa-tools package. To invoke
1863 vxloader automatically, add the following to /etc/modprobe.conf
1865 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1867 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1868 /etc/modules.conf, instead.)
1869 IBL size defines the interrupts period for PCM. The smaller size
1870 gives smaller latency but leads to more CPU consumption, too.
1871 The size is usually aligned to 126. As default (=0), the smallest
1872 size is chosen. The possible IBL values can be found in
1873 /proc/asound/cardX/vx-status proc file.
1875 The power-management is supported.
1880 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1882 ibl - Capture IBL size. (default = 0, minimum size)
1884 This module supports multiple cards. The module is compiled only when
1885 PCMCIA is supported on kernel.
1887 With the older 2.6.x kernel, to activate the driver via the card
1888 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1889 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1890 longer require a config file.
1892 When the driver is compiled as a module and the hotplug firmware
1893 is supported, the firmware data is loaded via hotplug automatically.
1894 Install the necessary firmware files in alsa-firmware package.
1895 When no hotplug fw loader is available, you need to load the
1896 firmware via vxloader utility in alsa-tools package.
1898 About capture IBL, see the description of snd-vx222 module.
1900 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1903 The power-management is supported.
1908 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x).
1910 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default,
1911 1 (auto-detect for YMF744/754 only)
1912 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default
1913 1 (auto-detect for YMF744/754 only)
1914 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default,
1916 rear_switch - enable shared rear/line-in switch (bool)
1918 This module supports autoprobe and multiple chips.
1920 The power-management is supported.
1922 Module snd-pdaudiocf
1923 --------------------
1925 Module for Sound Core PDAudioCF sound card.
1927 The power-management is supported.
1933 The ac97_quirk option is used to enable/override the workaround for
1934 specific devices on drivers for on-board AC'97 controllers like
1935 snd-intel8x0. Some hardware have swapped output pins between Master
1936 and Headphone, or Surround (thanks to confusion of AC'97
1937 specifications from version to version :-)
1939 The driver provides the auto-detection of known problematic devices,
1940 but some might be unknown or wrongly detected. In such a case, pass
1941 the proper value with this option.
1943 The following strings are accepted:
1944 - default Don't override the default setting
1945 - none Disable the quirk
1946 - hp_only Bind Master and Headphone controls as a single control
1947 - swap_hp Swap headphone and master controls
1948 - swap_surround Swap master and surround controls
1949 - ad_sharing For AD1985, turn on OMS bit and use headphone
1950 - alc_jack For ALC65x, turn on the jack sense mode
1951 - inv_eapd Inverted EAPD implementation
1952 - mute_led Bind EAPD bit for turning on/off mute LED
1954 For backward compatibility, the corresponding integer value -1, 0,
1955 ... are accepted, too.
1957 For example, if "Master" volume control has no effect on your device
1958 but only "Headphone" does, pass ac97_quirk=hp_only module option.
1961 Configuring Non-ISAPNP Cards
1962 ============================
1964 When the kernel is configured with ISA-PnP support, the modules
1965 supporting the isapnp cards will have module options "isapnp".
1966 If this option is set, *only* the ISA-PnP devices will be probed.
1967 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1968 together with the proper i/o and irq configuration.
1970 When the kernel is configured without ISA-PnP support, isapnp option
1971 will be not built in.
1974 Module Autoloading Support
1975 ==========================
1977 The ALSA drivers can be loaded automatically on demand by defining
1978 module aliases. The string 'snd-card-%1' is requested for ALSA native
1979 devices where %i is sound card number from zero to seven.
1981 To auto-load an ALSA driver for OSS services, define the string
1982 'sound-slot-%i' where %i means the slot number for OSS, which
1983 corresponds to the card index of ALSA. Usually, define this
1984 as the same card module.
1986 An example configuration for a single emu10k1 card is like below:
1987 ----- /etc/modprobe.conf
1988 alias snd-card-0 snd-emu10k1
1989 alias sound-slot-0 snd-emu10k1
1990 ----- /etc/modprobe.conf
1992 The available number of auto-loaded sound cards depends on the module
1993 option "cards_limit" of snd module. As default it's set to 1.
1994 To enable the auto-loading of multiple cards, specify the number of
1995 sound cards in that option.
1997 When multiple cards are available, it'd better to specify the index
1998 number for each card via module option, too, so that the order of
1999 cards is kept consistent.
2001 An example configuration for two sound cards is like below:
2003 ----- /etc/modprobe.conf
2005 options snd cards_limit=2
2006 alias snd-card-0 snd-interwave
2007 alias snd-card-1 snd-ens1371
2008 options snd-interwave index=0
2009 options snd-ens1371 index=1
2011 alias sound-slot-0 snd-interwave
2012 alias sound-slot-1 snd-ens1371
2013 ----- /etc/modprobe.conf
2015 In this example, the interwave card is always loaded as the first card
2016 (index 0) and ens1371 as the second (index 1).
2019 ALSA PCM devices to OSS devices mapping
2020 =======================================
2022 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2023 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2024 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2025 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2026 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2027 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2028 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2029 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2030 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2032 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2033 sound card number and second means device number. The ALSA devices
2034 have either 'c' or 'p' suffix indicating the direction, capture and
2035 playback, respectively.
2037 Please note that the device mapping above may be varied via the module
2038 options of snd-pcm-oss module.
2041 Proc interfaces (/proc/asound)
2042 ==============================
2044 /proc/asound/card#/pcm#[cp]/oss
2045 -------------------------------
2046 String "erase" - erase all additional informations about OSS applications
2047 String "<app_name> <fragments> <fragment_size> [<options>]"
2049 <app_name> - name of application with (higher priority) or without path
2050 <fragments> - number of fragments or zero if auto
2051 <fragment_size> - size of fragment in bytes or zero if auto
2052 <options> - optional parameters
2053 - disable the application tries to open a pcm device for
2054 this channel but does not want to use it.
2055 (Cause a bug or mmap needs)
2056 It's good for Quake etc...
2057 - direct don't use plugins
2058 - block force block mode (rvplayer)
2059 - non-block force non-block mode
2060 - whole-frag write only whole fragments (optimization affecting
2062 - no-silence do not fill silence ahead to avoid clicks
2063 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2064 instead of filled blocks
2066 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2067 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2068 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2071 Early Buffer Allocation
2072 =======================
2074 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2075 sometimes it's too late to find such spaces when the driver module is
2076 actually loaded due to memory fragmentation. You can pre-allocate the
2077 PCM buffers by loading snd-page-alloc module and write commands to its
2078 proc file in prior, for example, in the early boot stage like
2079 /etc/init.d/*.local scripts.
2081 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2082 usage of page allocation. In writing, you can send the following
2083 commands to the snd-page-alloc driver:
2085 - add VENDOR DEVICE MASK SIZE BUFFERS
2087 VENDOR and DEVICE are PCI vendor and device IDs. They take
2088 integer numbers (0x prefix is needed for the hex).
2089 MASK is the PCI DMA mask. Pass 0 if not restricted.
2090 SIZE is the size of each buffer to allocate. You can pass
2091 k and m suffix for KB and MB. The max number is 16MB.
2092 BUFFERS is the number of buffers to allocate. It must be greater
2093 than 0. The max number is 4.
2097 This will erase the all pre-allocated buffers which are not in
