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.
60 slots - Reserve the slot index for the given driver.
61 This option takes multiple strings.
62 See "Module Autoloading Support" section for details.
67 The PCM OSS emulation module.
68 This module takes options which change the mapping of devices.
70 dsp_map - PCM device number maps assigned to the 1st OSS device.
72 adsp_map - PCM device number maps assigned to the 2st OSS device.
75 - Don't block opening busy PCM devices. Default: 1
77 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
78 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
79 to PCM #0 of the card #0.
80 For changing the second or later card, specify the option with
81 commas, such like "dsp_map=0,1".
83 nonblock_open option is used to change the behavior of the PCM
84 regarding opening the device. When this option is non-zero,
85 opening a busy OSS PCM device won't be blocked but return
86 immediately with EAGAIN (just like O_NONBLOCK flag).
91 This module takes options which change the mapping of devices.
92 similar to those of the snd-pcm-oss module.
94 midi_map - MIDI device number maps assigned to the 1st OSS device.
96 amidi_map - MIDI device number maps assigned to the 2st OSS device.
99 Common parameters for top sound card modules
100 --------------------------------------------
102 Each of top level sound card module takes the following options.
104 index - index (slot #) of sound card
105 - Values: 0 through 31 or negative
106 - If nonnegative, assign that index number
107 - if negative, interpret as a bitmask of permissible
108 indices; the first free permitted index is assigned
110 id - card ID (identifier or name)
111 - Can be up to 15 characters long
112 - Default: the card type
113 - A directory by this name is created under /proc/asound/
114 containing information about the card
115 - This ID can be used instead of the index number in
118 - Default: enabled, for PCI and ISA PnP cards
123 Module for AdLib FM cards.
125 port - port # for OPL chip
127 This module supports multiple cards. It does not support autoprobe, so
128 the port must be specified. For actual AdLib FM cards it will be 0x388.
129 Note that this card does not have PCM support and no mixer; only FM
132 Make sure you have "sbiload" from the alsa-tools package available and,
133 after loading the module, find out the assigned ALSA sequencer port
134 number through "sbiload -l". Example output:
136 Port Client name Port name
137 64:0 OPL2 FM synth OPL2 FM Port
139 Load the std.sb and drums.sb patches also supplied by sbiload:
141 sbiload -p 64:0 std.sb drums.sb
143 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
144 instead. To have the card produce sound, use aplaymidi from alsa-utils:
146 aplaymidi -p 64:0 foo.mid

759 [Multiple options for each card instance]
760 model - force the model name
761 position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF)
762 probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
763 When the bit 8 (0x100) is set, the lower 8 bits are used
764 as the "fixed" codec slots; i.e. the driver probes the
765 slots regardless what hardware reports back
766 probe_only - Only probing and no codec initialization (default=off);
767 Useful to check the initial codec status for debugging
768 bdl_pos_adj - Specifies the DMA IRQ timing delay in samples.
769 Passing -1 will make the driver to choose the appropriate
770 value based on the controller chip.
772 [Single (global) options]
773 single_cmd - Use single immediate commands to communicate with
774 codecs (for debugging only)
775 enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
776 power_save - Automatic power-saving timtout (in second, 0 =
778 power_save_controller - Reset HD-audio controller in power-saving mode
781 This module supports multiple cards and autoprobe.
783 See Documentation/sound/alsa/HD-Audio.txt for more details about
786 Each codec may have a model table for different configurations.
787 If your machine isn't listed there, the default (usually minimal)
788 configuration is set up. You can pass "model=<name>" option to
789 specify a certain model in such a case. There are different
790 models depending on the codec chip. The list of available models
791 is found in HD-Audio-Models.txt
793 The model name "genric" is treated as a special case. When this
794 model is given, the driver uses the generic codec parser without
795 "codec-patch". It's sometimes good for testing and debugging.
797 If the default configuration doesn't work and one of the above
798 matches with your device, report it together with alsa-info.sh
799 output (with --no-upload option) to kernel bugzilla or alsa-devel
800 ML (see the section "Links and Addresses").
802 power_save and power_save_controller options are for power-saving
803 mode. See powersave.txt for details.
805 Note 2: If you get click noises on output, try the module option
806 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
807 register value without FIFO size correction as the current
808 DMA pointer. position_fix=2 will make the driver to use
809 the position buffer instead of reading SD_LPIB register.
810 (Usually SD_LPIB register is more accurate than the
813 NB: If you get many "azx_get_response timeout" messages at
814 loading, it's likely a problem of interrupts (e.g. ACPI irq
815 routing). Try to boot with options like "pci=noacpi". Also, you
816 can try "single_cmd=1" module option. This will switch the
817 communication method between HDA controller and codecs to the
818 single immediate commands instead of CORB/RIRB. Basically, the
819 single command mode is provided only for BIOS, and you won't get
820 unsolicited events, too. But, at least, this works independently
821 from the irq. Remember this is a last resort, and should be
822 avoided as much as possible...
824 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
825 On some hardwares, you may need to add a proper probe_mask option
826 to avoid the "azx_get_response timeout" problem above, instead.
827 This occurs when the access to non-existing or non-working codec slot
828 (likely a modem one) causes a stall of the communication via HD-audio
829 bus. You can see which codec slots are probed by enabling
830 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
831 proc files. Then limit the slots to probe by probe_mask option.
832 For example, probe_mask=1 means to probe only the first slot, and
833 probe_mask=4 means only the third slot.
835 The power-management is supported.
840 Module for RME Hammerfall DSP audio interface(s)
842 This module supports multiple cards.

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

1280 reset_workaround - enable AC97 RESET workaround for some laptops
1281 reset_workaround2 - enable extended AC97 RESET workaround for some
1284 This module supports one chip and autoprobe.
1286 The power-management is supported.
1288 Note: on some notebooks the buffer address cannot be detected
1289 automatically, or causes hang-up during initialization.
1290 In such a case, specify the buffer top address explicitly via
1291 the buffer_top option.

1294 Sony F270: buffer_top=0x272800
1295 The driver supports only ac97 codec. It's possible to force
1296 to initialize/use ac97 although it's not detected. In such a
1297 case, use force_ac97=1 option - but *NO* guarantee whether it
1300 Note: The NM256 chip can be linked internally with non-AC97
1301 codecs. This driver supports only the AC97 codec, and won't work
1302 with machines with other (most likely CS423x or OPL3SAx) chips,
1303 even though the device is detected in lspci. In such a case, try
1304 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1305 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1306 and proper hardware parameters in the case without ISA PnP.
1308 Note: some laptops need a workaround for AC97 RESET. For the
1309 known hardware like Dell Latitude LS and Sony PCG-F305, this
1310 workaround is enabled automatically. For other laptops with a
1311 hard freeze, you can try reset_workaround=1 option.
1313 Note: Dell Latitude CSx laptops have another problem regarding
1314 AC97 RESET. On these laptops, reset_workaround2 option is
1315 turned on as default. This option is worth to try if the
1316 previous reset_workaround option doesn't help.
1318 Note: This driver is really crappy. It's a porting from the
1319 OSS driver, which is a result of black-magic reverse engineering.
1320 The detection of codec will fail if the driver is loaded *after*
1321 X-server as described above. You might be able to force to load
1322 the module, but it may result in hang-up. Hence, make sure that
1323 you load this module *before* X if you encounter this kind of

1656 The below are options for wavefront_synth features:
1657 wf_raw - Assume that we need to boot the OS (default:no)
1658 If yes, then during driver loading, the state of the board is
1659 ignored, and we reset the board and load the firmware anyway.
1660 fx_raw - Assume that the FX process needs help (default:yes)
1661 If false, we'll leave the FX processor in whatever state it is
1662 when the driver is loaded. The default is to download the
1663 microprogram and associated coefficients to set it up for
1664 "default" operation, whatever that means.
1665 debug_default - Debug parameters for card initialization
1666 wait_usecs - How long to wait without sleeping, usecs
1668 This magic number seems to give pretty optimal throughput
1669 based on my limited experimentation.
1670 If you want to play around with it and find a better value, be
1671 my guest. Remember, the idea is to get a number that causes us
1672 to just busy wait for as many WaveFront commands as possible,
1673 without coming up with a number so large that we hog the whole
1675 Specifically, with this number, out of about 134,000 status
1676 waits, only about 250 result in a sleep.
1677 sleep_interval - How long to sleep when waiting for reply
1679 sleep_tries - How many times to try sleeping during a wait
1681 ospath - Pathname to processed ICS2115 OS firmware
1682 (default:wavefront.os)
1683 The path name of the ISC2115 OS firmware. In the recent
1684 version, it's handled via firmware loader framework, so it
1685 must be installed in the proper path, typically,
1687 reset_time - How long to wait for a reset to take effect
1689 ramcheck_time - How many seconds to wait for the RAM test
1691 osrun_time - How many seconds to wait for the ICS2115 OS
1694 This module supports multiple cards and ISA PnP.
1696 Note: the firmware file "wavefront.os" was located in the earlier
1697 version in /etc. Now it's loaded via firmware loader, and
1698 must be in the proper firmware path, such as /lib/firmware.
1699 Copy (or symlink) the file appropriately if you get an error
1700 regarding firmware downloading after upgrading the kernel.

1771 This module supports multiple devices, autoprobe and hotplugging.
1773 NB: nrpacks parameter can be modified dynamically via sysfs.
1774 Don't put the value over 20. Changing via sysfs has no sanity
1776 NB: async_unlink=0 would cause Oops. It remains just for
1777 debugging purpose (if any).
1778 NB: ignore_ctl_error=1 may help when you get an error at accessing
1779 the mixer element such as URB error -22. This happens on some
1780 buggy USB device or the controller.

1819 ac97_quirk - AC'97 workaround for strange hardware
1820 See "AC97 Quirk Option" section below.
1822 This module supports one chip and autoprobe.
1824 Note: on some SMP motherboards like MSI 694D the interrupts might
1825 not be generated properly. In such a case, please try to
1826 set the SMP (or MPS) version on BIOS to 1.1 instead of
1827 default value 1.4. Then the interrupt number will be
1828 assigned under 15. You might also upgrade your BIOS.
1830 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1831 channels as the first PCM. On these channels, up to 4
1832 streams can be played at the same time, and the controller
1833 can perform sample rate conversion with separate rates for
1835 As default (dxs_support = 0), 48k fixed rate is chosen
1836 except for the known devices since the output is often
1837 noisy except for 48k on some mother boards due to the
1839 Please try once dxs_support=5 and if it works on other
1840 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1841 know the PCI subsystem vendor/device id's (output of
1843 If dxs_support=5 does not work, try dxs_support=4; if it
1844 doesn't work too, try dxs_support=1. (dxs_support=1 is
1845 usually for old motherboards. The correct implemented
1846 board should work with 4 or 5.) If it still doesn't
1847 work and the default setting is ok, dxs_support=3 is the
1848 right choice. If the default setting doesn't work at all,
1849 try dxs_support=2 to disable the DXS channels.
1850 In any cases, please let us know the result and the
1851 subsystem vendor/device ids. See "Links and Addresses"
1854 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1900 This module supports multiple cards.
1902 When the driver is compiled as a module and the hotplug firmware
1903 is supported, the firmware data is loaded via hotplug automatically.
1904 Install the necessary firmware files in alsa-firmware package.
1905 When no hotplug fw loader is available, you need to load the
1906 firmware via vxloader utility in alsa-tools package. To invoke
1907 vxloader automatically, add the following to /etc/modprobe.conf
1909 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1911 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1912 /etc/modules.conf, instead.)
1913 IBL size defines the interrupts period for PCM. The smaller size
1914 gives smaller latency but leads to more CPU consumption, too.
1915 The size is usually aligned to 126. As default (=0), the smallest
1916 size is chosen. The possible IBL values can be found in
1917 /proc/asound/cardX/vx-status proc file.
1919 The power-management is supported.
1924 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1926 ibl - Capture IBL size. (default = 0, minimum size)
1928 This module supports multiple cards. The module is compiled only when
1929 PCMCIA is supported on kernel.
1931 With the older 2.6.x kernel, to activate the driver via the card
1932 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1933 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1934 longer require a config file.
1936 When the driver is compiled as a module and the hotplug firmware
1937 is supported, the firmware data is loaded via hotplug automatically.
1938 Install the necessary firmware files in alsa-firmware package.
1939 When no hotplug fw loader is available, you need to load the
1940 firmware via vxloader utility in alsa-tools package.
1942 About capture IBL, see the description of snd-vx222 module.
1944 Note: snd-vxp440 driver is merged to snd-vxpocket driver since

1966 Module snd-pdaudiocf
1967 --------------------
1969 Module for Sound Core PDAudioCF sound card.
1971 The power-management is supported.
1977 The ac97_quirk option is used to enable/override the workaround for
1978 specific devices on drivers for on-board AC'97 controllers like
1979 snd-intel8x0. Some hardware have swapped output pins between Master
1980 and Headphone, or Surround (thanks to confusion of AC'97
1981 specifications from version to version :-)
1983 The driver provides the auto-detection of known problematic devices,
1984 but some might be unknown or wrongly detected. In such a case, pass
1985 the proper value with this option.
1987 The following strings are accepted:
1988 - default Don't override the default setting
1989 - none Disable the quirk
1990 - hp_only Bind Master and Headphone controls as a single control
1991 - swap_hp Swap headphone and master controls
1992 - swap_surround Swap master and surround controls
1993 - ad_sharing For AD1985, turn on OMS bit and use headphone
1994 - alc_jack For ALC65x, turn on the jack sense mode
1995 - inv_eapd Inverted EAPD implementation
1996 - mute_led Bind EAPD bit for turning on/off mute LED
1998 For backward compatibility, the corresponding integer value -1, 0,
1999 ... are accepted, too.
2001 For example, if "Master" volume control has no effect on your device
2002 but only "Headphone" does, pass ac97_quirk=hp_only module option.
2005 Configuring Non-ISAPNP Cards
2006 ============================
2008 When the kernel is configured with ISA-PnP support, the modules
2009 supporting the isapnp cards will have module options "isapnp".
2010 If this option is set, *only* the ISA-PnP devices will be probed.
2011 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2012 together with the proper i/o and irq configuration.
2014 When the kernel is configured without ISA-PnP support, isapnp option
2015 will be not built in.
2018 Module Autoloading Support
2019 ==========================
2021 The ALSA drivers can be loaded automatically on demand by defining
2022 module aliases. The string 'snd-card-%1' is requested for ALSA native
2023 devices where %i is sound card number from zero to seven.
2025 To auto-load an ALSA driver for OSS services, define the string
2026 'sound-slot-%i' where %i means the slot number for OSS, which
2027 corresponds to the card index of ALSA. Usually, define this
2028 as the same card module.
2030 An example configuration for a single emu10k1 card is like below:
2031 ----- /etc/modprobe.conf
2032 alias snd-card-0 snd-emu10k1
2033 alias sound-slot-0 snd-emu10k1
2034 ----- /etc/modprobe.conf
2036 The available number of auto-loaded sound cards depends on the module
2037 option "cards_limit" of snd module. As default it's set to 1.
2038 To enable the auto-loading of multiple cards, specify the number of
2039 sound cards in that option.
2041 When multiple cards are available, it'd better to specify the index
2042 number for each card via module option, too, so that the order of
2043 cards is kept consistent.
2045 An example configuration for two sound cards is like below:
2047 ----- /etc/modprobe.conf
2049 options snd cards_limit=2
2050 alias snd-card-0 snd-interwave
2051 alias snd-card-1 snd-ens1371
2052 options snd-interwave index=0
2053 options snd-ens1371 index=1
2055 alias sound-slot-0 snd-interwave
2056 alias sound-slot-1 snd-ens1371
2057 ----- /etc/modprobe.conf
2059 In this example, the interwave card is always loaded as the first card
2060 (index 0) and ens1371 as the second (index 1).
2062 Alternative (and new) way to fixate the slot assignment is to use
2063 "slots" option of snd module. In the case above, specify like the
2066 options snd slots=snd-interwave,snd-ens1371
2068 Then, the first slot (#0) is reserved for snd-interwave driver, and
2069 the second (#1) for snd-ens1371. You can omit index option in each
2070 driver if slots option is used (although you can still have them at
2071 the same time as long as they don't conflict).
2073 The slots option is especially useful for avoiding the possible
2074 hot-plugging and the resultant slot conflict. For example, in the
2075 case above again, the first two slots are already reserved. If any
2076 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2077 snd-ens1371, it will be assigned to the third or later slot.
2079 When a module name is given with '!', the slot will be given for any
2080 modules but that name. For example, "slots=!snd-pcsp" will reserve
2081 the first slot for any modules but snd-pcsp.
2084 ALSA PCM devices to OSS devices mapping
2085 =======================================
2087 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2088 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2089 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2090 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2091 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2092 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2093 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2094 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2095 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2097 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2098 sound card number and second means device number. The ALSA devices
2099 have either 'c' or 'p' suffix indicating the direction, capture and
2100 playback, respectively.
2102 Please note that the device mapping above may be varied via the module
2103 options of snd-pcm-oss module.
2106 Proc interfaces (/proc/asound)
2107 ==============================
2109 /proc/asound/card#/pcm#[cp]/oss
2110 -------------------------------
2111 String "erase" - erase all additional informations about OSS applications
2112 String "<app_name> <fragments> <fragment_size> [<options>]"
2114 <app_name> - name of application with (higher priority) or without path
2115 <fragments> - number of fragments or zero if auto
2116 <fragment_size> - size of fragment in bytes or zero if auto
2117 <options> - optional parameters
2118 - disable the application tries to open a pcm device for
2119 this channel but does not want to use it.
2120 (Cause a bug or mmap needs)
2121 It's good for Quake etc...
2122 - direct don't use plugins
2123 - block force block mode (rvplayer)
2124 - non-block force non-block mode
2125 - whole-frag write only whole fragments (optimization affecting
2127 - no-silence do not fill silence ahead to avoid clicks
2128 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2129 instead of filled blocks
2131 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2132 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2133 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2136 Early Buffer Allocation
2137 =======================
2139 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2140 sometimes it's too late to find such spaces when the driver module is
2141 actually loaded due to memory fragmentation. You can pre-allocate the
2142 PCM buffers by loading snd-page-alloc module and write commands to its
2143 proc file in prior, for example, in the early boot stage like
2144 /etc/init.d/*.local scripts.
2146 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2147 usage of page allocation. In writing, you can send the following
2148 commands to the snd-page-alloc driver:
2150 - add VENDOR DEVICE MASK SIZE BUFFERS
2152 VENDOR and DEVICE are PCI vendor and device IDs. They take
2153 integer numbers (0x prefix is needed for the hex).
2154 MASK is the PCI DMA mask. Pass 0 if not restricted.
2155 SIZE is the size of each buffer to allocate. You can pass
2156 k and m suffix for KB and MB. The max number is 16MB.
2157 BUFFERS is the number of buffers to allocate. It must be greater
2158 than 0. The max number is 4.
2162 This will erase the all pre-allocated buffers which are not in
