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

957 The model name "genric" is treated as a special case. When this
958 model is given, the driver uses the generic codec parser without
959 "codec-patch". It's sometimes good for testing and debugging.
961 If the default configuration doesn't work and one of the above
962 matches with your device, report it together with the PCI
963 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
964 ML (see the section "Links and Addresses").
966 Note 2: If you get click noises on output, try the module option
967 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
968 register value without FIFO size correction as the current
969 DMA pointer. position_fix=2 will make the driver to use
970 the position buffer instead of reading SD_LPIB register.
971 (Usually SD_LPLIB register is more accurate than the
974 NB: If you get many "azx_get_response timeout" messages at
975 loading, it's likely a problem of interrupts (e.g. ACPI irq
976 routing). Try to boot with options like "pci=noacpi". Also, you
977 can try "single_cmd=1" module option. This will switch the
978 communication method between HDA controller and codecs to the
979 single immediate commands instead of CORB/RIRB. Basically, the
980 single command mode is provided only for BIOS, and you won't get
981 unsolicited events, too. But, at least, this works independently
982 from the irq. Remember this is a last resort, and should be
983 avoided as much as possible...
985 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
986 On some hardwares, you may need to add a proper probe_mask option
987 to avoid the "azx_get_response timeout" problem above, instead.
988 This occurs when the access to non-existing or non-working codec slot
989 (likely a modem one) causes a stall of the communication via HD-audio
990 bus. You can see which codec slots are probed by enabling
991 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
992 proc files. Then limit the slots to probe by probe_mask option.
993 For example, probe_mask=1 means to probe only the first slot, and
994 probe_mask=4 means only the third slot.
996 The power-management is supported.
1001 Module for RME Hammerfall DSP audio interface(s)
1003 This module supports multiple cards.

1383 with machines with other (most likely CS423x or OPL3SAx) chips,
1384 even though the device is detected in lspci. In such a case, try
1385 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1386 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1387 and proper hardware parameters in the case without ISA PnP.
1389 Note: some laptops need a workaround for AC97 RESET. For the
1390 known hardware like Dell Latitude LS and Sony PCG-F305, this
1391 workaround is enabled automatically. For other laptops with a
1392 hard freeze, you can try reset_workaround=1 option.
1394 Note: Dell Latitude CSx laptops have another problem regarding
1395 AC97 RESET. On these laptops, reset_workaround2 option is
1396 turned on as default. This option is worth to try if the
1397 previous reset_workaround option doesn't help.
1399 Note: This driver is really crappy. It's a porting from the
1400 OSS driver, which is a result of black-magic reverse engineering.
1401 The detection of codec will fail if the driver is loaded *after*
1402 X-server as described above. You might be able to force to load
1403 the module, but it may result in hang-up. Hence, make sure that
1404 you load this module *before* X if you encounter this kind of

1778 ac97_quirk - AC'97 workaround for strange hardware
1779 See "AC97 Quirk Option" section below.
1781 This module supports one chip and autoprobe.
1783 Note: on some SMP motherboards like MSI 694D the interrupts might
1784 not be generated properly. In such a case, please try to
1785 set the SMP (or MPS) version on BIOS to 1.1 instead of
1786 default value 1.4. Then the interrupt number will be
1787 assigned under 15. You might also upgrade your BIOS.
1789 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1790 channels as the first PCM. On these channels, up to 4
1791 streams can be played at the same time, and the controller
1792 can perform sample rate conversion with separate rates for
1794 As default (dxs_support = 0), 48k fixed rate is chosen
1795 except for the known devices since the output is often
1796 noisy except for 48k on some mother boards due to the
1798 Please try once dxs_support=5 and if it works on other
1799 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1800 know the PCI subsystem vendor/device id's (output of
1802 If dxs_support=5 does not work, try dxs_support=4; if it
1803 doesn't work too, try dxs_support=1. (dxs_support=1 is
1804 usually for old motherboards. The correct implemented
1805 board should work with 4 or 5.) If it still doesn't
1806 work and the default setting is ok, dxs_support=3 is the
1807 right choice. If the default setting doesn't work at all,
1808 try dxs_support=2 to disable the DXS channels.
1809 In any cases, please let us know the result and the
1810 subsystem vendor/device ids. See "Links and Addresses"
1813 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1830 The power-management is supported.
1835 Module for virtual rawmidi devices.
1836 This module creates virtual rawmidi devices which communicate
1837 to the corresponding ALSA sequencer ports.
1839 midi_devs - MIDI devices # (1-4, default=4)

1846 Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards.
1848 mic - Enable Microphone on V222 Mic (NYI)
1849 ibl - Capture IBL size. (default = 0, minimum size)
1851 This module supports multiple cards.
1853 When the driver is compiled as a module and the hotplug firmware
1854 is supported, the firmware data is loaded via hotplug automatically.
1855 Install the necessary firmware files in alsa-firmware package.
1856 When no hotplug fw loader is available, you need to load the
1857 firmware via vxloader utility in alsa-tools package. To invoke
1858 vxloader automatically, add the following to /etc/modprobe.conf
1860 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1862 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1863 /etc/modules.conf, instead.)
1864 IBL size defines the interrupts period for PCM. The smaller size
1865 gives smaller latency but leads to more CPU consumption, too.
1866 The size is usually aligned to 126. As default (=0), the smallest
1867 size is chosen. The possible IBL values can be found in
1868 /proc/asound/cardX/vx-status proc file.
1870 The power-management is supported.
1875 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1877 ibl - Capture IBL size. (default = 0, minimum size)
1879 This module supports multiple cards. The module is compiled only when
1880 PCMCIA is supported on kernel.
1882 With the older 2.6.x kernel, to activate the driver via the card
1883 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1884 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1885 longer require a config file.
1887 When the driver is compiled as a module and the hotplug firmware
1888 is supported, the firmware data is loaded via hotplug automatically.
1889 Install the necessary firmware files in alsa-firmware package.
1890 When no hotplug fw loader is available, you need to load the
1891 firmware via vxloader utility in alsa-tools package.
1893 About capture IBL, see the description of snd-vx222 module.
1895 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1898 The power-management is supported.
1903 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x).
1905 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default,
1906 1 (auto-detect for YMF744/754 only)
1907 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default
1908 1 (auto-detect for YMF744/754 only)
1909 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default,
1911 rear_switch - enable shared rear/line-in switch (bool)
1913 This module supports autoprobe and multiple chips.
1915 The power-management is supported.
1917 Module snd-pdaudiocf
1918 --------------------
1920 Module for Sound Core PDAudioCF sound card.
1922 The power-management is supported.
1928 The ac97_quirk option is used to enable/override the workaround for
1929 specific devices on drivers for on-board AC'97 controllers like
1930 snd-intel8x0. Some hardware have swapped output pins between Master
1931 and Headphone, or Surround (thanks to confusion of AC'97
1932 specifications from version to version :-)
1934 The driver provides the auto-detection of known problematic devices,
1935 but some might be unknown or wrongly detected. In such a case, pass
1936 the proper value with this option.
1938 The following strings are accepted:
1939 - default Don't override the default setting
1940 - none Disable the quirk
1941 - hp_only Bind Master and Headphone controls as a single control
1942 - swap_hp Swap headphone and master controls
1943 - swap_surround Swap master and surround controls
1944 - ad_sharing For AD1985, turn on OMS bit and use headphone
1945 - alc_jack For ALC65x, turn on the jack sense mode
1946 - inv_eapd Inverted EAPD implementation
1947 - mute_led Bind EAPD bit for turning on/off mute LED
1949 For backward compatibility, the corresponding integer value -1, 0,
1950 ... are accepted, too.
1952 For example, if "Master" volume control has no effect on your device
1953 but only "Headphone" does, pass ac97_quirk=hp_only module option.
1956 Configuring Non-ISAPNP Cards
1957 ============================
1959 When the kernel is configured with ISA-PnP support, the modules
1960 supporting the isapnp cards will have module options "isapnp".
1961 If this option is set, *only* the ISA-PnP devices will be probed.
1962 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1963 together with the proper i/o and irq configuration.
1965 When the kernel is configured without ISA-PnP support, isapnp option
1966 will be not built in.
1969 Module Autoloading Support
1970 ==========================
1972 The ALSA drivers can be loaded automatically on demand by defining
1973 module aliases. The string 'snd-card-%1' is requested for ALSA native
1974 devices where %i is sound card number from zero to seven.
1976 To auto-load an ALSA driver for OSS services, define the string
1977 'sound-slot-%i' where %i means the slot number for OSS, which
1978 corresponds to the card index of ALSA. Usually, define this
1979 as the same card module.
1981 An example configuration for a single emu10k1 card is like below:
1982 ----- /etc/modprobe.conf
1983 alias snd-card-0 snd-emu10k1
1984 alias sound-slot-0 snd-emu10k1
1985 ----- /etc/modprobe.conf
1987 The available number of auto-loaded sound cards depends on the module
1988 option "cards_limit" of snd module. As default it's set to 1.
1989 To enable the auto-loading of multiple cards, specify the number of
1990 sound cards in that option.
1992 When multiple cards are available, it'd better to specify the index
1993 number for each card via module option, too, so that the order of
1994 cards is kept consistent.
1996 An example configuration for two sound cards is like below:
1998 ----- /etc/modprobe.conf
2000 options snd cards_limit=2
2001 alias snd-card-0 snd-interwave
2002 alias snd-card-1 snd-ens1371
2003 options snd-interwave index=0
2004 options snd-ens1371 index=1
2006 alias sound-slot-0 snd-interwave
2007 alias sound-slot-1 snd-ens1371
2008 ----- /etc/modprobe.conf
2010 In this example, the interwave card is always loaded as the first card
2011 (index 0) and ens1371 as the second (index 1).
2014 ALSA PCM devices to OSS devices mapping
2015 =======================================
2017 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2018 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2019 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2020 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2021 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2022 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2023 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2024 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2025 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2027 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2028 sound card number and second means device number. The ALSA devices
2029 have either 'c' or 'p' suffix indicating the direction, capture and
2030 playback, respectively.
2032 Please note that the device mapping above may be varied via the module
2033 options of snd-pcm-oss module.
2036 Proc interfaces (/proc/asound)
2037 ==============================
2039 /proc/asound/card#/pcm#[cp]/oss
2040 -------------------------------
2041 String "erase" - erase all additional informations about OSS applications
2042 String "<app_name> <fragments> <fragment_size> [<options>]"
2044 <app_name> - name of application with (higher priority) or without path
2045 <fragments> - number of fragments or zero if auto
2046 <fragment_size> - size of fragment in bytes or zero if auto
2047 <options> - optional parameters
2048 - disable the application tries to open a pcm device for
2049 this channel but does not want to use it.
2050 (Cause a bug or mmap needs)
2051 It's good for Quake etc...
2052 - direct don't use plugins
2053 - block force block mode (rvplayer)
2054 - non-block force non-block mode
2055 - whole-frag write only whole fragments (optimization affecting
2057 - no-silence do not fill silence ahead to avoid clicks
2058 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2059 instead of filled blocks
2061 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2062 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2063 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2066 Early Buffer Allocation
2067 =======================
2069 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2070 sometimes it's too late to find such spaces when the driver module is
2071 actually loaded due to memory fragmentation. You can pre-allocate the
2072 PCM buffers by loading snd-page-alloc module and write commands to its
2073 proc file in prior, for example, in the early boot stage like
2074 /etc/init.d/*.local scripts.
2076 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2077 usage of page allocation. In writing, you can send the following
2078 commands to the snd-page-alloc driver:
2080 - add VENDOR DEVICE MASK SIZE BUFFERS
2082 VENDOR and DEVICE are PCI vendor and device IDs. They take
2083 integer numbers (0x prefix is needed for the hex).
2084 MASK is the PCI DMA mask. Pass 0 if not restricted.
2085 SIZE is the size of each buffer to allocate. You can pass
2086 k and m suffix for KB and MB. The max number is 16MB.
2087 BUFFERS is the number of buffers to allocate. It must be greater
2088 than 0. The max number is 4.
2092 This will erase the all pre-allocated buffers which are not in
