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

996 The model name "genric" is treated as a special case. When this
997 model is given, the driver uses the generic codec parser without
998 "codec-patch". It's sometimes good for testing and debugging.
1000 If the default configuration doesn't work and one of the above
1001 matches with your device, report it together with the PCI
1002 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
1003 ML (see the section "Links and Addresses").
1005 When CONFIG_SND_HDA_POWER_SAVE is set, two options, power_save and
1006 power_save_controller become available. power_save specifies the
1007 time to turn off the power automatically at idle status. When
1008 power_save_controller is true, the controller is also turned off.
1009 This might result in more obvious click noise at turning on/off.
1011 Note 2: If you get click noises on output, try the module option
1012 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
1013 register value without FIFO size correction as the current
1014 DMA pointer. position_fix=2 will make the driver to use
1015 the position buffer instead of reading SD_LPIB register.
1016 (Usually SD_LPLIB register is more accurate than the
1019 NB: If you get many "azx_get_response timeout" messages at
1020 loading, it's likely a problem of interrupts (e.g. ACPI irq
1021 routing). Try to boot with options like "pci=noacpi". Also, you
1022 can try "single_cmd=1" module option. This will switch the
1023 communication method between HDA controller and codecs to the
1024 single immediate commands instead of CORB/RIRB. Basically, the
1025 single command mode is provided only for BIOS, and you won't get
1026 unsolicited events, too. But, at least, this works independently
1027 from the irq. Remember this is a last resort, and should be
1028 avoided as much as possible...
1030 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1031 On some hardwares, you may need to add a proper probe_mask option
1032 to avoid the "azx_get_response timeout" problem above, instead.
1033 This occurs when the access to non-existing or non-working codec slot
1034 (likely a modem one) causes a stall of the communication via HD-audio
1035 bus. You can see which codec slots are probed by enabling
1036 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1037 proc files. Then limit the slots to probe by probe_mask option.
1038 For example, probe_mask=1 means to probe only the first slot, and
1039 probe_mask=4 means only the third slot.
1041 The power-management is supported.
1046 Module for RME Hammerfall DSP audio interface(s)
1048 This module supports multiple cards.
1050 Note: The firmware data can be automatically loaded via hotplug
1051 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1052 the firmware via hdsploader utility included in alsa-tools
1054 The firmware data is found in alsa-firmware package.
1056 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1057 module did formerly. It will allocate the buffers in advance
1058 when any HDSP cards are found. To make the buffer
1059 allocation sure, load snd-page-alloc module in the early
1060 stage of boot sequence. See "Early Buffer Allocation"

1402 force_ac97 - 0 or 1 (disabled by default)
1403 buffer_top - specify buffer top address
1404 use_cache - 0 or 1 (disabled by default)
1405 vaio_hack - alias buffer_top=0x25a800
1406 reset_workaround - enable AC97 RESET workaround for some laptops
1407 reset_workaround2 - enable extended AC97 RESET workaround for some
1410 This module supports one chip and autoprobe.
1412 The power-management is supported.
1414 Note: on some notebooks the buffer address cannot be detected
1415 automatically, or causes hang-up during initialization.
1416 In such a case, specify the buffer top address explicitly via
1417 the buffer_top option.
1419 Sony F250: buffer_top=0x25a800
1420 Sony F270: buffer_top=0x272800
1421 The driver supports only ac97 codec. It's possible to force
1422 to initialize/use ac97 although it's not detected. In such a
1423 case, use force_ac97=1 option - but *NO* guarantee whether it
1426 Note: The NM256 chip can be linked internally with non-AC97
1427 codecs. This driver supports only the AC97 codec, and won't work
1428 with machines with other (most likely CS423x or OPL3SAx) chips,
1429 even though the device is detected in lspci. In such a case, try
1430 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1431 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1432 and proper hardware parameters in the case without ISA PnP.
1434 Note: some laptops need a workaround for AC97 RESET. For the
1435 known hardware like Dell Latitude LS and Sony PCG-F305, this
1436 workaround is enabled automatically. For other laptops with a
1437 hard freeze, you can try reset_workaround=1 option.
1439 Note: Dell Latitude CSx laptops have another problem regarding
1440 AC97 RESET. On these laptops, reset_workaround2 option is
1441 turned on as default. This option is worth to try if the
1442 previous reset_workaround option doesn't help.
1444 Note: This driver is really crappy. It's a porting from the
1445 OSS driver, which is a result of black-magic reverse engineering.
1446 The detection of codec will fail if the driver is loaded *after*
1447 X-server as described above. You might be able to force to load
1448 the module, but it may result in hang-up. Hence, make sure that
1449 you load this module *before* X if you encounter this kind of

1717 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default)
1719 The below are options for wavefront_synth features:
1720 wf_raw - Assume that we need to boot the OS (default:no)
1721 If yes, then during driver loading, the state of the board is
1722 ignored, and we reset the board and load the firmware anyway.
1723 fx_raw - Assume that the FX process needs help (default:yes)
1724 If false, we'll leave the FX processor in whatever state it is
1725 when the driver is loaded. The default is to download the
1726 microprogram and associated coefficients to set it up for
1727 "default" operation, whatever that means.
1728 debug_default - Debug parameters for card initialization
1729 wait_usecs - How long to wait without sleeping, usecs
1731 This magic number seems to give pretty optimal throughput
1732 based on my limited experimentation.
1733 If you want to play around with it and find a better value, be
1734 my guest. Remember, the idea is to get a number that causes us
1735 to just busy wait for as many WaveFront commands as possible,
1736 without coming up with a number so large that we hog the whole
1738 Specifically, with this number, out of about 134,000 status
1739 waits, only about 250 result in a sleep.
1740 sleep_interval - How long to sleep when waiting for reply
1742 sleep_tries - How many times to try sleeping during a wait
1744 ospath - Pathname to processed ICS2115 OS firmware
1745 (default:wavefront.os)
1746 The path name of the ISC2115 OS firmware. In the recent
1747 version, it's handled via firmware loader framework, so it
1748 must be installed in the proper path, typically,
1750 reset_time - How long to wait for a reset to take effect
1752 ramcheck_time - How many seconds to wait for the RAM test
1754 osrun_time - How many seconds to wait for the ICS2115 OS
1757 This module supports multiple cards and ISA PnP.
1759 Note: the firmware file "wavefront.os" was located in the earlier
1760 version in /etc. Now it's loaded via firmware loader, and
1761 must be in the proper firmware path, such as /lib/firmware.
1762 Copy (or symlink) the file appropriately if you get an error
1763 regarding firmware downloading after upgrading the kernel.

1868 See "AC97 Quirk Option" section below.
1870 This module supports one chip and autoprobe.
1872 Note: on some SMP motherboards like MSI 694D the interrupts might
1873 not be generated properly. In such a case, please try to
1874 set the SMP (or MPS) version on BIOS to 1.1 instead of
1875 default value 1.4. Then the interrupt number will be
1876 assigned under 15. You might also upgrade your BIOS.
1878 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1879 channels as the first PCM. On these channels, up to 4
1880 streams can be played at the same time, and the controller
1881 can perform sample rate conversion with separate rates for
1883 As default (dxs_support = 0), 48k fixed rate is chosen
1884 except for the known devices since the output is often
1885 noisy except for 48k on some mother boards due to the
1887 Please try once dxs_support=5 and if it works on other
1888 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1889 know the PCI subsystem vendor/device id's (output of
1891 If dxs_support=5 does not work, try dxs_support=4; if it
1892 doesn't work too, try dxs_support=1. (dxs_support=1 is
1893 usually for old motherboards. The correct implemented
1894 board should work with 4 or 5.) If it still doesn't
1895 work and the default setting is ok, dxs_support=3 is the
1896 right choice. If the default setting doesn't work at all,
1897 try dxs_support=2 to disable the DXS channels.
1898 In any cases, please let us know the result and the
1899 subsystem vendor/device ids. See "Links and Addresses"
1902 Note: for the MPU401 on VIA823x, use snd-mpu401 driver
1903 additionally. The mpu_port option is for VIA686 chips only.
1905 The power-management is supported.

1940 This module supports multiple cards.
1942 When the driver is compiled as a module and the hotplug firmware
1943 is supported, the firmware data is loaded via hotplug automatically.
1944 Install the necessary firmware files in alsa-firmware package.
1945 When no hotplug fw loader is available, you need to load the
1946 firmware via vxloader utility in alsa-tools package. To invoke
1947 vxloader automatically, add the following to /etc/modprobe.conf
1949 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1951 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1952 /etc/modules.conf, instead.)
1953 IBL size defines the interrupts period for PCM. The smaller size
1954 gives smaller latency but leads to more CPU consumption, too.
1955 The size is usually aligned to 126. As default (=0), the smallest
1956 size is chosen. The possible IBL values can be found in
1957 /proc/asound/cardX/vx-status proc file.
1959 The power-management is supported.
1964 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1966 ibl - Capture IBL size. (default = 0, minimum size)
1968 This module supports multiple cards. The module is compiled only when
1969 PCMCIA is supported on kernel.
1971 With the older 2.6.x kernel, to activate the driver via the card
1972 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1973 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1974 longer require a config file.
1976 When the driver is compiled as a module and the hotplug firmware
1977 is supported, the firmware data is loaded via hotplug automatically.
1978 Install the necessary firmware files in alsa-firmware package.
1979 When no hotplug fw loader is available, you need to load the
1980 firmware via vxloader utility in alsa-tools package.
1982 About capture IBL, see the description of snd-vx222 module.
1984 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1987 The power-management is supported.
1992 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x).
1994 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default,
1995 1 (auto-detect for YMF744/754 only)
1996 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default
1997 1 (auto-detect for YMF744/754 only)
1998 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default,
2000 rear_switch - enable shared rear/line-in switch (bool)
2002 This module supports autoprobe and multiple chips.
2004 The power-management is supported.
2006 Module snd-pdaudiocf
2007 --------------------
2009 Module for Sound Core PDAudioCF sound card.
2011 The power-management is supported.
2017 The ac97_quirk option is used to enable/override the workaround for
2018 specific devices on drivers for on-board AC'97 controllers like
2019 snd-intel8x0. Some hardware have swapped output pins between Master
2020 and Headphone, or Surround (thanks to confusion of AC'97
2021 specifications from version to version :-)
2023 The driver provides the auto-detection of known problematic devices,
2024 but some might be unknown or wrongly detected. In such a case, pass
2025 the proper value with this option.
2027 The following strings are accepted:
2028 - default Don't override the default setting
2029 - none Disable the quirk
2030 - hp_only Bind Master and Headphone controls as a single control
2031 - swap_hp Swap headphone and master controls
2032 - swap_surround Swap master and surround controls
2033 - ad_sharing For AD1985, turn on OMS bit and use headphone
2034 - alc_jack For ALC65x, turn on the jack sense mode
2035 - inv_eapd Inverted EAPD implementation
2036 - mute_led Bind EAPD bit for turning on/off mute LED
2038 For backward compatibility, the corresponding integer value -1, 0,
2039 ... are accepted, too.
2041 For example, if "Master" volume control has no effect on your device
2042 but only "Headphone" does, pass ac97_quirk=hp_only module option.
2045 Configuring Non-ISAPNP Cards
2046 ============================
2048 When the kernel is configured with ISA-PnP support, the modules
2049 supporting the isapnp cards will have module options "isapnp".
2050 If this option is set, *only* the ISA-PnP devices will be probed.
2051 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2052 together with the proper i/o and irq configuration.
2054 When the kernel is configured without ISA-PnP support, isapnp option
2055 will be not built in.
2058 Module Autoloading Support
2059 ==========================
2061 The ALSA drivers can be loaded automatically on demand by defining
2062 module aliases. The string 'snd-card-%1' is requested for ALSA native
2063 devices where %i is sound card number from zero to seven.
2065 To auto-load an ALSA driver for OSS services, define the string
2066 'sound-slot-%i' where %i means the slot number for OSS, which
2067 corresponds to the card index of ALSA. Usually, define this
2068 as the same card module.
2070 An example configuration for a single emu10k1 card is like below:
2071 ----- /etc/modprobe.conf
2072 alias snd-card-0 snd-emu10k1
2073 alias sound-slot-0 snd-emu10k1
2074 ----- /etc/modprobe.conf
2076 The available number of auto-loaded sound cards depends on the module
2077 option "cards_limit" of snd module. As default it's set to 1.
2078 To enable the auto-loading of multiple cards, specify the number of
2079 sound cards in that option.
2081 When multiple cards are available, it'd better to specify the index
2082 number for each card via module option, too, so that the order of
2083 cards is kept consistent.
2085 An example configuration for two sound cards is like below:
2087 ----- /etc/modprobe.conf
2089 options snd cards_limit=2
2090 alias snd-card-0 snd-interwave
2091 alias snd-card-1 snd-ens1371
2092 options snd-interwave index=0
2093 options snd-ens1371 index=1
2095 alias sound-slot-0 snd-interwave
2096 alias sound-slot-1 snd-ens1371
2097 ----- /etc/modprobe.conf
2099 In this example, the interwave card is always loaded as the first card
2100 (index 0) and ens1371 as the second (index 1).
2103 ALSA PCM devices to OSS devices mapping
2104 =======================================
2106 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2107 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2108 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2109 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2110 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2111 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2112 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2113 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2114 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2116 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2117 sound card number and second means device number. The ALSA devices
2118 have either 'c' or 'p' suffix indicating the direction, capture and
2119 playback, respectively.
2121 Please note that the device mapping above may be varied via the module
2122 options of snd-pcm-oss module.
2125 Proc interfaces (/proc/asound)
2126 ==============================
2128 /proc/asound/card#/pcm#[cp]/oss
2129 -------------------------------
2130 String "erase" - erase all additional informations about OSS applications
2131 String "<app_name> <fragments> <fragment_size> [<options>]"
2133 <app_name> - name of application with (higher priority) or without path
2134 <fragments> - number of fragments or zero if auto
2135 <fragment_size> - size of fragment in bytes or zero if auto
2136 <options> - optional parameters
2137 - disable the application tries to open a pcm device for
2138 this channel but does not want to use it.
2139 (Cause a bug or mmap needs)
2140 It's good for Quake etc...
2141 - direct don't use plugins
2142 - block force block mode (rvplayer)
2143 - non-block force non-block mode
2144 - whole-frag write only whole fragments (optimization affecting
2146 - no-silence do not fill silence ahead to avoid clicks
2147 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2148 instead of filled blocks
2150 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2151 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2152 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2155 Early Buffer Allocation
2156 =======================
2158 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2159 sometimes it's too late to find such spaces when the driver module is
2160 actually loaded due to memory fragmentation. You can pre-allocate the
2161 PCM buffers by loading snd-page-alloc module and write commands to its
2162 proc file in prior, for example, in the early boot stage like
2163 /etc/init.d/*.local scripts.
2165 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2166 usage of page allocation. In writing, you can send the following
2167 commands to the snd-page-alloc driver:
2169 - add VENDOR DEVICE MASK SIZE BUFFERS
2171 VENDOR and DEVICE are PCI vendor and device IDs. They take
2172 integer numbers (0x prefix is needed for the hex).
2173 MASK is the PCI DMA mask. Pass 0 if not restricted.
2174 SIZE is the size of each buffer to allocate. You can pass
2175 k and m suffix for KB and MB. The max number is 16MB.
2176 BUFFERS is the number of buffers to allocate. It must be greater
2177 than 0. The max number is 4.
2181 This will erase the all pre-allocated buffers which are not in
