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.

1281 reset_workaround - enable AC97 RESET workaround for some laptops
1282 reset_workaround2 - enable extended AC97 RESET workaround for some
1285 This module supports one chip and autoprobe.
1287 The power-management is supported.
1289 Note: on some notebooks the buffer address cannot be detected
1290 automatically, or causes hang-up during initialization.
1291 In such a case, specify the buffer top address explicitly via
1292 the buffer_top option.

1296 The driver supports only ac97 codec. It's possible to force
1297 to initialize/use ac97 although it's not detected. In such a
1298 case, use force_ac97=1 option - but *NO* guarantee whether it
1301 Note: The NM256 chip can be linked internally with non-AC97
1302 codecs. This driver supports only the AC97 codec, and won't work
1303 with machines with other (most likely CS423x or OPL3SAx) chips,
1304 even though the device is detected in lspci. In such a case, try
1305 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1306 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1307 and proper hardware parameters in the case without ISA PnP.
1309 Note: some laptops need a workaround for AC97 RESET. For the
1310 known hardware like Dell Latitude LS and Sony PCG-F305, this
1311 workaround is enabled automatically. For other laptops with a
1312 hard freeze, you can try reset_workaround=1 option.
1314 Note: Dell Latitude CSx laptops have another problem regarding
1315 AC97 RESET. On these laptops, reset_workaround2 option is
1316 turned on as default. This option is worth to try if the
1317 previous reset_workaround option doesn't help.
1319 Note: This driver is really crappy. It's a porting from the
1320 OSS driver, which is a result of black-magic reverse engineering.
1321 The detection of codec will fail if the driver is loaded *after*
1322 X-server as described above. You might be able to force to load
1323 the module, but it may result in hang-up. Hence, make sure that
1324 you load this module *before* X if you encounter this kind of

1657 The below are options for wavefront_synth features:
1658 wf_raw - Assume that we need to boot the OS (default:no)
1659 If yes, then during driver loading, the state of the board is
1660 ignored, and we reset the board and load the firmware anyway.
1661 fx_raw - Assume that the FX process needs help (default:yes)
1662 If false, we'll leave the FX processor in whatever state it is
1663 when the driver is loaded. The default is to download the
1664 microprogram and associated coefficients to set it up for
1665 "default" operation, whatever that means.
1666 debug_default - Debug parameters for card initialization
1667 wait_usecs - How long to wait without sleeping, usecs
1669 This magic number seems to give pretty optimal throughput
1670 based on my limited experimentation.
1671 If you want to play around with it and find a better value, be
1672 my guest. Remember, the idea is to get a number that causes us
1673 to just busy wait for as many WaveFront commands as possible,
1674 without coming up with a number so large that we hog the whole
1676 Specifically, with this number, out of about 134,000 status
1677 waits, only about 250 result in a sleep.
1678 sleep_interval - How long to sleep when waiting for reply
1680 sleep_tries - How many times to try sleeping during a wait
1682 ospath - Pathname to processed ICS2115 OS firmware
1683 (default:wavefront.os)
1684 The path name of the ISC2115 OS firmware. In the recent
1685 version, it's handled via firmware loader framework, so it
1686 must be installed in the proper path, typically,
1688 reset_time - How long to wait for a reset to take effect
1690 ramcheck_time - How many seconds to wait for the RAM test
1692 osrun_time - How many seconds to wait for the ICS2115 OS
1695 This module supports multiple cards and ISA PnP.
1697 Note: the firmware file "wavefront.os" was located in the earlier
1698 version in /etc. Now it's loaded via firmware loader, and
1699 must be in the proper firmware path, such as /lib/firmware.
1700 Copy (or symlink) the file appropriately if you get an error
1701 regarding firmware downloading after upgrading the kernel.

1772 This module supports multiple devices, autoprobe and hotplugging.
1774 NB: nrpacks parameter can be modified dynamically via sysfs.
1775 Don't put the value over 20. Changing via sysfs has no sanity
1777 NB: async_unlink=0 would cause Oops. It remains just for
1778 debugging purpose (if any).
1779 NB: ignore_ctl_error=1 may help when you get an error at accessing
1780 the mixer element such as URB error -22. This happens on some
1781 buggy USB device or the controller.

1820 ac97_quirk - AC'97 workaround for strange hardware
1821 See "AC97 Quirk Option" section below.
1823 This module supports one chip and autoprobe.
1825 Note: on some SMP motherboards like MSI 694D the interrupts might
1826 not be generated properly. In such a case, please try to
1827 set the SMP (or MPS) version on BIOS to 1.1 instead of
1828 default value 1.4. Then the interrupt number will be
1829 assigned under 15. You might also upgrade your BIOS.
1831 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1832 channels as the first PCM. On these channels, up to 4
1833 streams can be played at the same time, and the controller
1834 can perform sample rate conversion with separate rates for
1836 As default (dxs_support = 0), 48k fixed rate is chosen
1837 except for the known devices since the output is often
1838 noisy except for 48k on some mother boards due to the
1840 Please try once dxs_support=5 and if it works on other
1841 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1842 know the PCI subsystem vendor/device id's (output of
1844 If dxs_support=5 does not work, try dxs_support=4; if it
1845 doesn't work too, try dxs_support=1. (dxs_support=1 is
1846 usually for old motherboards. The correct implemented
1847 board should work with 4 or 5.) If it still doesn't
1848 work and the default setting is ok, dxs_support=3 is the
1849 right choice. If the default setting doesn't work at all,
1850 try dxs_support=2 to disable the DXS channels.
1851 In any cases, please let us know the result and the
1852 subsystem vendor/device ids. See "Links and Addresses"
1855 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1901 This module supports multiple cards.
1903 When the driver is compiled as a module and the hotplug firmware
1904 is supported, the firmware data is loaded via hotplug automatically.
1905 Install the necessary firmware files in alsa-firmware package.
1906 When no hotplug fw loader is available, you need to load the
1907 firmware via vxloader utility in alsa-tools package. To invoke
1908 vxloader automatically, add the following to /etc/modprobe.conf
1910 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1912 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1913 /etc/modules.conf, instead.)
1914 IBL size defines the interrupts period for PCM. The smaller size
1915 gives smaller latency but leads to more CPU consumption, too.
1916 The size is usually aligned to 126. As default (=0), the smallest
1917 size is chosen. The possible IBL values can be found in
1918 /proc/asound/cardX/vx-status proc file.
1920 The power-management is supported.
1925 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1927 ibl - Capture IBL size. (default = 0, minimum size)
1929 This module supports multiple cards. The module is compiled only when
1930 PCMCIA is supported on kernel.
1932 With the older 2.6.x kernel, to activate the driver via the card
1933 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1934 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1935 longer require a config file.
1937 When the driver is compiled as a module and the hotplug firmware
1938 is supported, the firmware data is loaded via hotplug automatically.
1939 Install the necessary firmware files in alsa-firmware package.
1940 When no hotplug fw loader is available, you need to load the
1941 firmware via vxloader utility in alsa-tools package.
1943 About capture IBL, see the description of snd-vx222 module.
1945 Note: snd-vxp440 driver is merged to snd-vxpocket driver since

1967 Module snd-pdaudiocf
1968 --------------------
1970 Module for Sound Core PDAudioCF sound card.
1972 The power-management is supported.
1978 The ac97_quirk option is used to enable/override the workaround for
1979 specific devices on drivers for on-board AC'97 controllers like
1980 snd-intel8x0. Some hardware have swapped output pins between Master
1981 and Headphone, or Surround (thanks to confusion of AC'97
1982 specifications from version to version :-)
1984 The driver provides the auto-detection of known problematic devices,
1985 but some might be unknown or wrongly detected. In such a case, pass
1986 the proper value with this option.
1988 The following strings are accepted:
1989 - default Don't override the default setting
1990 - none Disable the quirk
1991 - hp_only Bind Master and Headphone controls as a single control
1992 - swap_hp Swap headphone and master controls
1993 - swap_surround Swap master and surround controls
1994 - ad_sharing For AD1985, turn on OMS bit and use headphone
1995 - alc_jack For ALC65x, turn on the jack sense mode
1996 - inv_eapd Inverted EAPD implementation
1997 - mute_led Bind EAPD bit for turning on/off mute LED
1999 For backward compatibility, the corresponding integer value -1, 0,
2000 ... are accepted, too.
2002 For example, if "Master" volume control has no effect on your device
2003 but only "Headphone" does, pass ac97_quirk=hp_only module option.
2006 Configuring Non-ISAPNP Cards
2007 ============================
2009 When the kernel is configured with ISA-PnP support, the modules
2010 supporting the isapnp cards will have module options "isapnp".
2011 If this option is set, *only* the ISA-PnP devices will be probed.
2012 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2013 together with the proper i/o and irq configuration.
2015 When the kernel is configured without ISA-PnP support, isapnp option
2016 will be not built in.
2019 Module Autoloading Support
2020 ==========================
2022 The ALSA drivers can be loaded automatically on demand by defining
2023 module aliases. The string 'snd-card-%1' is requested for ALSA native
2024 devices where %i is sound card number from zero to seven.
2026 To auto-load an ALSA driver for OSS services, define the string
2027 'sound-slot-%i' where %i means the slot number for OSS, which
2028 corresponds to the card index of ALSA. Usually, define this
2029 as the same card module.
2031 An example configuration for a single emu10k1 card is like below:
2032 ----- /etc/modprobe.conf
2033 alias snd-card-0 snd-emu10k1
2034 alias sound-slot-0 snd-emu10k1
2035 ----- /etc/modprobe.conf
2037 The available number of auto-loaded sound cards depends on the module
2038 option "cards_limit" of snd module. As default it's set to 1.
2039 To enable the auto-loading of multiple cards, specify the number of
2040 sound cards in that option.
2042 When multiple cards are available, it'd better to specify the index
2043 number for each card via module option, too, so that the order of
2044 cards is kept consistent.
2046 An example configuration for two sound cards is like below:
2048 ----- /etc/modprobe.conf
2050 options snd cards_limit=2
2051 alias snd-card-0 snd-interwave
2052 alias snd-card-1 snd-ens1371
2053 options snd-interwave index=0
2054 options snd-ens1371 index=1
2056 alias sound-slot-0 snd-interwave
2057 alias sound-slot-1 snd-ens1371
2058 ----- /etc/modprobe.conf
2060 In this example, the interwave card is always loaded as the first card
2061 (index 0) and ens1371 as the second (index 1).
2063 Alternative (and new) way to fixate the slot assignment is to use
2064 "slots" option of snd module. In the case above, specify like the
2067 options snd slots=snd-interwave,snd-ens1371
2069 Then, the first slot (#0) is reserved for snd-interwave driver, and
2070 the second (#1) for snd-ens1371. You can omit index option in each
2071 driver if slots option is used (although you can still have them at
2072 the same time as long as they don't conflict).
2074 The slots option is especially useful for avoiding the possible
2075 hot-plugging and the resultant slot conflict. For example, in the
2076 case above again, the first two slots are already reserved. If any
2077 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2078 snd-ens1371, it will be assigned to the third or later slot.
2080 When a module name is given with '!', the slot will be given for any
2081 modules but that name. For example, "slots=!snd-pcsp" will reserve
2082 the first slot for any modules but snd-pcsp.
2085 ALSA PCM devices to OSS devices mapping
2086 =======================================
2088 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2089 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2090 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2091 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2092 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2093 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2094 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2095 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2096 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2098 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2099 sound card number and second means device number. The ALSA devices
2100 have either 'c' or 'p' suffix indicating the direction, capture and
2101 playback, respectively.
2103 Please note that the device mapping above may be varied via the module
2104 options of snd-pcm-oss module.
2107 Proc interfaces (/proc/asound)
2108 ==============================
2110 /proc/asound/card#/pcm#[cp]/oss
2111 -------------------------------
2112 String "erase" - erase all additional informations about OSS applications
2113 String "<app_name> <fragments> <fragment_size> [<options>]"
2115 <app_name> - name of application with (higher priority) or without path
2116 <fragments> - number of fragments or zero if auto
2117 <fragment_size> - size of fragment in bytes or zero if auto
2118 <options> - optional parameters
2119 - disable the application tries to open a pcm device for
2120 this channel but does not want to use it.
2121 (Cause a bug or mmap needs)
2122 It's good for Quake etc...
2123 - direct don't use plugins
2124 - block force block mode (rvplayer)
2125 - non-block force non-block mode
2126 - whole-frag write only whole fragments (optimization affecting
2128 - no-silence do not fill silence ahead to avoid clicks
2129 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2130 instead of filled blocks
2132 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2133 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2134 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2137 Early Buffer Allocation
2138 =======================
2140 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2141 sometimes it's too late to find such spaces when the driver module is
2142 actually loaded due to memory fragmentation. You can pre-allocate the
2143 PCM buffers by loading snd-page-alloc module and write commands to its
2144 proc file in prior, for example, in the early boot stage like
2145 /etc/init.d/*.local scripts.
2147 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2148 usage of page allocation. In writing, you can send the following
2149 commands to the snd-page-alloc driver:
2151 - add VENDOR DEVICE MASK SIZE BUFFERS
2153 VENDOR and DEVICE are PCI vendor and device IDs. They take
2154 integer numbers (0x prefix is needed for the hex).
2155 MASK is the PCI DMA mask. Pass 0 if not restricted.
2156 SIZE is the size of each buffer to allocate. You can pass
2157 k and m suffix for KB and MB. The max number is 16MB.
2158 BUFFERS is the number of buffers to allocate. It must be greater
2159 than 0. The max number is 4.
2163 This will erase the all pre-allocated buffers which are not in
