Advanced Linux Sound Architecture - Driver
|
|
==========================================
|
|
Configuration guide
|
|
|
|
|
|
Kernel Configuration
|
|
====================
|
|
|
|
To enable ALSA support you need at least to build the kernel with
|
|
primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS,
|
|
you don't have to choose any of the OSS modules.
|
|
|
|
Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
|
|
PCM supports if you want to run OSS applications with ALSA.
|
|
|
|
If you want to support the WaveTable functionality on cards such as
|
|
SB Live! then you need to enable "Sequencer support"
|
|
(CONFIG_SND_SEQUENCER).
|
|
|
|
To make ALSA debug messages more verbose, enable the "Verbose printk"
|
|
and "Debug" options. To check for memory leaks, turn on "Debug memory"
|
|
too. "Debug detection" will add checks for the detection of cards.
|
|
|
|
Please note that all the ALSA ISA drivers support the Linux isapnp API
|
|
(if the card supports ISA PnP). You don't need to configure the cards
|
|
using isapnptools.
|
|
|
|
|
|
Creating ALSA devices
|
|
=====================
|
|
|
|
This depends on your distribution, but normally you use the /dev/MAKEDEV
|
|
script to create the necessary device nodes. On some systems you use a
|
|
script named 'snddevices'.
|
|
|
|
|
|
Module parameters
|
|
=================
|
|
|
|
The user can load modules with options. If the module supports more than
|
|
one card and you have more than one card of the same type then you can
|
|
specify multiple values for the option separated by commas.
|
|
|
|
Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
|
|
|
|
Module snd
|
|
----------
|
|
|
|
The core ALSA module. It is used by all ALSA card drivers.
|
|
It takes the following options which have global effects.
|
|
|
|
major - major number for sound driver
|
|
- Default: 116
|
|
cards_limit
|
|
- limiting card index for auto-loading (1-8)
|
|
- Default: 1
|
|
- For auto-loading more than one card, specify this
|
|
option together with snd-card-X aliases.
|
|
slots - Reserve the slot index for the given driver.
|
|
This option takes multiple strings.
|
|
See "Module Autoloading Support" section for details.
|
|
debug - Specifies the debug message level
|
|
(0 = disable debug prints, 1 = normal debug messages,
|
|
2 = verbose debug messages)
|
|
This option appears only when CONFIG_SND_DEBUG=y.
|
|
This option can be dynamically changed via sysfs
|
|
/sys/modules/snd/parameters/debug file.
|
|
|
|
Module snd-pcm-oss
|
|
------------------
|
|
|
|
The PCM OSS emulation module.
|
|
This module takes options which change the mapping of devices.
|
|
|
|
dsp_map - PCM device number maps assigned to the 1st OSS device.
|
|
- Default: 0
|
|
adsp_map - PCM device number maps assigned to the 2st OSS device.
|
|
- Default: 1
|
|
nonblock_open
|
|
- Don't block opening busy PCM devices. Default: 1
|
|
|
|
For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
|
|
the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
|
|
to PCM #0 of the card #0.
|
|
For changing the second or later card, specify the option with
|
|
commas, such like "dsp_map=0,1".
|
|
|
|
nonblock_open option is used to change the behavior of the PCM
|
|
regarding opening the device. When this option is non-zero,
|
|
opening a busy OSS PCM device won't be blocked but return
|
|
immediately with EAGAIN (just like O_NONBLOCK flag).
|
|
|
|
Module snd-rawmidi
|
|
------------------
|
|
|
|
This module takes options which change the mapping of devices.
|
|
similar to those of the snd-pcm-oss module.
|
|
|
|
midi_map - MIDI device number maps assigned to the 1st OSS device.
|
|
- Default: 0
|
|
amidi_map - MIDI device number maps assigned to the 2st OSS device.
|
|
- Default: 1
|
|
|
|
Common parameters for top sound card modules
|
|
--------------------------------------------
|
|
|
|
Each of top level sound card module takes the following options.
|
|
|
|
index - index (slot #) of sound card
|
|
- Values: 0 through 31 or negative
|
|
- If nonnegative, assign that index number
|
|
- if negative, interpret as a bitmask of permissible
|
|
indices; the first free permitted index is assigned
|
|
- Default: -1
|
|
id - card ID (identifier or name)
|
|
- Can be up to 15 characters long
|
|
- Default: the card type
|
|
- A directory by this name is created under /proc/asound/
|
|
containing information about the card
|
|
- This ID can be used instead of the index number in
|
|
identifying the card
|
|
enable - enable card
|
|
- Default: enabled, for PCI and ISA PnP cards
|
|
|
|
Module snd-adlib
|
|
----------------
|
|
|
|
Module for AdLib FM cards.
|
|
|
|
port - port # for OPL chip
|
|
|
|
This module supports multiple cards. It does not support autoprobe, so
|
|
the port must be specified. For actual AdLib FM cards it will be 0x388.
|
|
Note that this card does not have PCM support and no mixer; only FM
|
|
synthesis.
|
|
|
|
Make sure you have "sbiload" from the alsa-tools package available and,
|
|
after loading the module, find out the assigned ALSA sequencer port
|
|
number through "sbiload -l". Example output:
|
|
|
|
Port Client name Port name
|
|
64:0 OPL2 FM synth OPL2 FM Port
|
|
|
|
Load the std.sb and drums.sb patches also supplied by sbiload:
|
|
|
|
sbiload -p 64:0 std.sb drums.sb
|
|
|
|
If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
|
|
instead. To have the card produce sound, use aplaymidi from alsa-utils:
|
|
|
|
aplaymidi -p 64:0 foo.mid

|
or input, but you may use this module for any application which
|
|
requires a sound card (like RealPlayer).
|
|

|
|
but either ignores read/write or mmap a single dummy page to all
|
|
buffer pages, in order to save the resouces. If your apps need
|

[Multiple options for each card instance]
|
|
model - force the model name
|
|
position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF,
|
|
3 = VIACOMBO, 4 = COMBO)
|
|
probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
|
|
When the bit 8 (0x100) is set, the lower 8 bits are used
|
|
as the "fixed" codec slots; i.e. the driver probes the
|
|
slots regardless what hardware reports back
|
|
probe_only - Only probing and no codec initialization (default=off);
|
|
Useful to check the initial codec status for debugging
|
|
bdl_pos_adj - Specifies the DMA IRQ timing delay in samples.
|
|
Passing -1 will make the driver to choose the appropriate
|
|
value based on the controller chip.
|
|
patch - Specifies the early "patch" files to modify the HD-audio
|
|
setup before initializing the codecs. This option is
|
|
available only when CONFIG_SND_HDA_PATCH_LOADER=y is set.
|
|
See HD-Audio.txt for details.
|
|
beep_mode - Selects the beep registration mode (0=off, 1=on, 2=
|
|
dynamic registration via mute switch on/off); the default
|
|
value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig.
|
|
|
|
[Single (global) options]
|
|
single_cmd - Use single immediate commands to communicate with
|
|
codecs (for debugging only)
|
|
enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
|
|
power_save - Automatic power-saving timeout (in second, 0 =
|
|
disable)
|
|
power_save_controller - Reset HD-audio controller in power-saving mode
|
|
(default = on)
|
|
align_buffer_size - Force rounding of buffer/period sizes to multiples
|
|
of 128 bytes. This is more efficient in terms of memory
|
|
access but isn't required by the HDA spec and prevents
|
|
users from specifying exact period/buffer sizes.
|
|
(default = on)
|
|
snoop - Enable/disable snooping (default = on)
|
|
|
|
This module supports multiple cards and autoprobe.
|
|
|
|
See Documentation/sound/alsa/HD-Audio.txt for more details about
|
|
HD-audio driver.
|
|
|
|
Each codec may have a model table for different configurations.
|
|
If your machine isn't listed there, the default (usually minimal)
|
|
configuration is set up. You can pass "model=<name>" option to
|
|
specify a certain model in such a case. There are different
|
|
models depending on the codec chip. The list of available models
|
|
is found in HD-Audio-Models.txt
|
|
|
|
The model name "genric" is treated as a special case. When this
|
|
model is given, the driver uses the generic codec parser without
|
|
"codec-patch". It's sometimes good for testing and debugging.
|
|
|
|
If the default configuration doesn't work and one of the above
|
|
matches with your device, report it together with alsa-info.sh
|
|
output (with --no-upload option) to kernel bugzilla or alsa-devel
|
|
ML (see the section "Links and Addresses").
|
|
|
|
power_save and power_save_controller options are for power-saving
|
|
mode. See powersave.txt for details.
|
|
|
|
Note 2: If you get click noises on output, try the module option
|
|
position_fix=1 or 2. position_fix=1 will use the SD_LPIB
|
|
register value without FIFO size correction as the current
|
|
DMA pointer. position_fix=2 will make the driver to use
|
|
the position buffer instead of reading SD_LPIB register.
|
|
(Usually SD_LPIB register is more accurate than the
|
|
position buffer.)
|
|
|
|
position_fix=3 is specific to VIA devices. The position
|
|
of the capture stream is checked from both LPIB and POSBUF
|
|
values. position_fix=4 is a combination mode, using LPIB
|
|
for playback and POSBUF for capture.
|
|
|
|
NB: If you get many "azx_get_response timeout" messages at
|
|
loading, it's likely a problem of interrupts (e.g. ACPI irq
|
|
routing). Try to boot with options like "pci=noacpi". Also, you
|
|
can try "single_cmd=1" module option. This will switch the
|
|
communication method between HDA controller and codecs to the
|
|
single immediate commands instead of CORB/RIRB. Basically, the
|
|
single command mode is provided only for BIOS, and you won't get
|
|
unsolicited events, too. But, at least, this works independently
|
|
from the irq. Remember this is a last resort, and should be
|
|
avoided as much as possible...
|
|
|
|
MORE NOTES ON "azx_get_response timeout" PROBLEMS:
|
|
On some hardwares, you may need to add a proper probe_mask option
|
|
to avoid the "azx_get_response timeout" problem above, instead.
|
|
This occurs when the access to non-existing or non-working codec slot
|
|
(likely a modem one) causes a stall of the communication via HD-audio
|
|
bus. You can see which codec slots are probed by enabling
|
|
CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
|
|
proc files. Then limit the slots to probe by probe_mask option.
|
|
For example, probe_mask=1 means to probe only the first slot, and
|
|
probe_mask=4 means only the third slot.

|
|
|
|
Module snd-nm256
|
|
----------------
|
|
|
|
Module for NeoMagic NM256AV/ZX chips
|
|
|
|
playback_bufsize - max playback frame size in kB (4-128kB)
|
|
capture_bufsize - max capture frame size in kB (4-128kB)
|
|
force_ac97 - 0 or 1 (disabled by default)
|
|
buffer_top - specify buffer top address
|
|
use_cache - 0 or 1 (disabled by default)
|
|
vaio_hack - alias buffer_top=0x25a800
|
|
reset_workaround - enable AC97 RESET workaround for some laptops
|
|
reset_workaround2 - enable extended AC97 RESET workaround for some
|
|
other laptops
|
|
|
|
This module supports one chip and autoprobe.
|
|
|
|
The power-management is supported.
|
|
|
|
Note: on some notebooks the buffer address cannot be detected
|
|
automatically, or causes hang-up during initialization.
|
|
In such a case, specify the buffer top address explicitly via
|
|
the buffer_top option.
|
|
For example,
|
|
Sony F250: buffer_top=0x25a800
|
|
Sony F270: buffer_top=0x272800
|
|
The driver supports only ac97 codec. It's possible to force
|
|
to initialize/use ac97 although it's not detected. In such a
|
|
case, use force_ac97=1 option - but *NO* guarantee whether it
|
|
works!
|
|
|
|
Note: The NM256 chip can be linked internally with non-AC97
|
|
codecs. This driver supports only the AC97 codec, and won't work
|
|
with machines with other (most likely CS423x or OPL3SAx) chips,
|
|
even though the device is detected in lspci. In such a case, try
|
|
other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
|
|
but some doesn't have ISA PnP. You'll need to specify isapnp=0
|
|
and proper hardware parameters in the case without ISA PnP.
|
|
|
|
Note: some laptops need a workaround for AC97 RESET. For the
|
|
known hardware like Dell Latitude LS and Sony PCG-F305, this
|
|
workaround is enabled automatically. For other laptops with a
|
|
hard freeze, you can try reset_workaround=1 option.
|
|
|
|
Note: Dell Latitude CSx laptops have another problem regarding
|
|
AC97 RESET. On these laptops, reset_workaround2 option is
|
|
turned on as default. This option is worth to try if the
|
|
previous reset_workaround option doesn't help.
|
|
|
|
Note: This driver is really crappy. It's a porting from the
|
|
OSS driver, which is a result of black-magic reverse engineering.
|
|
The detection of codec will fail if the driver is loaded *after*
|
|
X-server as described above. You might be able to force to load
|
|
the module, but it may result in hang-up. Hence, make sure that
|

|
|
|
The below are options for wavefront_synth features:
|
|
wf_raw - Assume that we need to boot the OS (default:no)
|
|
If yes, then during driver loading, the state of the board is
|
|
ignored, and we reset the board and load the firmware anyway.
|
|
fx_raw - Assume that the FX process needs help (default:yes)
|
|
If false, we'll leave the FX processor in whatever state it is
|
|
when the driver is loaded. The default is to download the
|
|
microprogram and associated coefficients to set it up for
|
|
"default" operation, whatever that means.
|
|
debug_default - Debug parameters for card initialization
|
|
wait_usecs - How long to wait without sleeping, usecs
|
|
(default:150)
|
|
This magic number seems to give pretty optimal throughput
|
|
based on my limited experimentation.
|
|
If you want to play around with it and find a better value, be
|
|
my guest. Remember, the idea is to get a number that causes us
|
|
to just busy wait for as many WaveFront commands as possible,
|
|
without coming up with a number so large that we hog the whole
|
|
CPU.
|
|
Specifically, with this number, out of about 134,000 status
|
|
waits, only about 250 result in a sleep.
|
|
sleep_interval - How long to sleep when waiting for reply
|
|
(default: 100)
|
|
sleep_tries - How many times to try sleeping during a wait
|
|
(default: 50)
|
|
ospath - Pathname to processed ICS2115 OS firmware
|
|
(default:wavefront.os)
|
|
The path name of the ISC2115 OS firmware. In the recent
|
|
version, it's handled via firmware loader framework, so it
|
|
must be installed in the proper path, typically,
|
|
/lib/firmware.
|
|
reset_time - How long to wait for a reset to take effect
|
|
(default:2)
|
|
ramcheck_time - How many seconds to wait for the RAM test
|
|
(default:20)
|
|
osrun_time - How many seconds to wait for the ICS2115 OS
|
|
(default:10)
|
|
|
|
This module supports multiple cards and ISA PnP.
|
|
|
|
Note: the firmware file "wavefront.os" was located in the earlier
|
|
version in /etc. Now it's loaded via firmware loader, and
|
|
must be in the proper firmware path, such as /lib/firmware.
|
|
Copy (or symlink) the file appropriately if you get an error
|
|
regarding firmware downloading after upgrading the kernel.

|
ac97_quirk - AC'97 workaround for strange hardware
|
|
See "AC97 Quirk Option" section below.
|
|
|
|
This module supports one chip and autoprobe.
|
|
|
|
Note: on some SMP motherboards like MSI 694D the interrupts might
|
|
not be generated properly. In such a case, please try to
|
|
set the SMP (or MPS) version on BIOS to 1.1 instead of
|
|
default value 1.4. Then the interrupt number will be
|
|
assigned under 15. You might also upgrade your BIOS.
|
|
|
|
Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
|
|
channels as the first PCM. On these channels, up to 4
|
|
streams can be played at the same time, and the controller
|
|
can perform sample rate conversion with separate rates for
|
|
each channel.
|
|
As default (dxs_support = 0), 48k fixed rate is chosen
|
|
except for the known devices since the output is often
|
|
noisy except for 48k on some mother boards due to the
|
|
bug of BIOS.
|
|
Please try once dxs_support=5 and if it works on other
|
|
sample rates (e.g. 44.1kHz of mp3 playback), please let us
|
|
know the PCI subsystem vendor/device id's (output of
|
|
"lspci -nv").
|
|
If dxs_support=5 does not work, try dxs_support=4; if it
|
|
doesn't work too, try dxs_support=1. (dxs_support=1 is
|
|
usually for old motherboards. The correct implemented
|
|
board should work with 4 or 5.) If it still doesn't
|
|
work and the default setting is ok, dxs_support=3 is the
|
|
right choice. If the default setting doesn't work at all,
|
|
try dxs_support=2 to disable the DXS channels.
|
|
In any cases, please let us know the result and the
|
|
subsystem vendor/device ids. See "Links and Addresses"
|
|
below.
|
|
|
|
Note: for the MPU401 on VIA823x, use snd-mpu401 driver
|
|
additionally. The mpu_port option is for VIA686 chips only.
|
|
|
|
The power-management is supported.
|
|

|
|
|
The power-management is supported.
|
|
|
|
Module snd-virmidi
|
|
------------------
|
|
|
|

|
|
This module creates virtual rawmidi devices which communicate
|
|
to the corresponding ALSA sequencer ports.
|
|
|
|
midi_devs - MIDI devices # (1-4, default=4)
|
|
|
|
This module supports multiple cards.
|
|
|
|
Module snd-virtuoso
|
|
-------------------
|
|
|
|
Module for sound cards based on the Asus AV66/AV100/AV200 chips,
|
|
i.e., Xonar D1, DX, D2, D2X, DS, Essence ST (Deluxe), Essence STX,
|
|
HDAV1.3 (Deluxe), and HDAV1.3 Slim.
|
|
|
|
This module supports autoprobe and multiple cards.
|
|
|
|
Module snd-vx222
|
|
----------------
|
|
|
|
Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards.
|
|
|
|
mic - Enable Microphone on V222 Mic (NYI)
|
|
ibl - Capture IBL size. (default = 0, minimum size)
|
|
|
|
This module supports multiple cards.
|
|
|
|
When the driver is compiled as a module and the hotplug firmware
|
|
is supported, the firmware data is loaded via hotplug automatically.
|
|
Install the necessary firmware files in alsa-firmware package.
|
|
When no hotplug fw loader is available, you need to load the
|
|
firmware via vxloader utility in alsa-tools package. To invoke
|
|
vxloader automatically, add the following to /etc/modprobe.d/alsa.conf
|
|
|
|
install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
|
|
|
|
(for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
|
|
/etc/modules.conf, instead.)
|
|
IBL size defines the interrupts period for PCM. The smaller size
|
|
gives smaller latency but leads to more CPU consumption, too.
|
|
The size is usually aligned to 126. As default (=0), the smallest
|
|
size is chosen. The possible IBL values can be found in
|
|
/proc/asound/cardX/vx-status proc file.
|
|
|
|
The power-management is supported.
|
|
|
|
Module snd-vxpocket
|
|
-------------------
|
|
|
|
Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
|
|
|
|
ibl - Capture IBL size. (default = 0, minimum size)
|
|
|
|
This module supports multiple cards. The module is compiled only when
|
|
PCMCIA is supported on kernel.
|
|
|
|
With the older 2.6.x kernel, to activate the driver via the card
|
|
manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
|
|
sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
|
|
longer require a config file.
|
|
|
|
When the driver is compiled as a module and the hotplug firmware
|
|
is supported, the firmware data is loaded via hotplug automatically.
|
|
Install the necessary firmware files in alsa-firmware package.
|
|
When no hotplug fw loader is available, you need to load the
|
|
firmware via vxloader utility in alsa-tools package.
|
|
|
|
About capture IBL, see the description of snd-vx222 module.
|
|
|
|
Note: snd-vxp440 driver is merged to snd-vxpocket driver since
|
|

|
|
|
AC97 Quirk Option
|
|
=================
|
|
|
|
The ac97_quirk option is used to enable/override the workaround for
|
|
specific devices on drivers for on-board AC'97 controllers like
|
|
snd-intel8x0. Some hardware have swapped output pins between Master
|
|
and Headphone, or Surround (thanks to confusion of AC'97
|
|
specifications from version to version :-)
|
|
|
|
The driver provides the auto-detection of known problematic devices,
|
|
but some might be unknown or wrongly detected. In such a case, pass
|
|
the proper value with this option.
|
|
|
|
The following strings are accepted:
|
|
- default Don't override the default setting
|
|
- none Disable the quirk
|
|
- hp_only Bind Master and Headphone controls as a single control
|
|
- swap_hp Swap headphone and master controls
|
|
- swap_surround Swap master and surround controls
|
|
- ad_sharing For AD1985, turn on OMS bit and use headphone
|
|
- alc_jack For ALC65x, turn on the jack sense mode
|
|
- inv_eapd Inverted EAPD implementation
|
|
- mute_led Bind EAPD bit for turning on/off mute LED
|
|
|
|
For backward compatibility, the corresponding integer value -1, 0,
|
|
... are accepted, too.
|
|
|
|
For example, if "Master" volume control has no effect on your device
|
|
but only "Headphone" does, pass ac97_quirk=hp_only module option.
|
|
|
|
|
|
Configuring Non-ISAPNP Cards
|
|
============================
|
|
|
|
When the kernel is configured with ISA-PnP support, the modules
|
|
supporting the isapnp cards will have module options "isapnp".
|
|
If this option is set, *only* the ISA-PnP devices will be probed.
|
|
For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
|
|
together with the proper i/o and irq configuration.
|
|
|
|
When the kernel is configured without ISA-PnP support, isapnp option
|
|
will be not built in.
|
|
|
|
|
|
Module Autoloading Support
|
|
==========================
|
|
|
|
The ALSA drivers can be loaded automatically on demand by defining
|
|
module aliases. The string 'snd-card-%1' is requested for ALSA native
|
|
devices where %i is sound card number from zero to seven.
|
|
|
|
To auto-load an ALSA driver for OSS services, define the string
|
|
'sound-slot-%i' where %i means the slot number for OSS, which
|
|
corresponds to the card index of ALSA. Usually, define this
|
|
as the same card module.
|
|
|
|
An example configuration for a single emu10k1 card is like below:
|
|
----- /etc/modprobe.d/alsa.conf
|
|
alias snd-card-0 snd-emu10k1
|
|
alias sound-slot-0 snd-emu10k1
|
|
----- /etc/modprobe.d/alsa.conf
|
|
|
|
The available number of auto-loaded sound cards depends on the module
|
|
option "cards_limit" of snd module. As default it's set to 1.
|
|
To enable the auto-loading of multiple cards, specify the number of
|
|
sound cards in that option.
|
|
|
|
When multiple cards are available, it'd better to specify the index
|
|
number for each card via module option, too, so that the order of
|
|
cards is kept consistent.
|
|
|
|
An example configuration for two sound cards is like below:
|
|
|
|
----- /etc/modprobe.d/alsa.conf
|
|
# ALSA portion
|
|
options snd cards_limit=2
|
|
alias snd-card-0 snd-interwave
|
|
alias snd-card-1 snd-ens1371
|
|
options snd-interwave index=0
|
|
options snd-ens1371 index=1
|
|
# OSS/Free portion
|
|
alias sound-slot-0 snd-interwave
|
|
alias sound-slot-1 snd-ens1371
|
|
----- /etc/modprobe.d/alsa.conf
|
|
|
|
In this example, the interwave card is always loaded as the first card
|
|
(index 0) and ens1371 as the second (index 1).
|
|
|
|
Alternative (and new) way to fixate the slot assignment is to use
|
|
"slots" option of snd module. In the case above, specify like the
|
|
following:
|
|
|
|
options snd slots=snd-interwave,snd-ens1371
|
|
|
|
Then, the first slot (#0) is reserved for snd-interwave driver, and
|
|
the second (#1) for snd-ens1371. You can omit index option in each
|
|
driver if slots option is used (although you can still have them at
|
|
the same time as long as they don't conflict).
|
|
|
|
The slots option is especially useful for avoiding the possible
|
|
hot-plugging and the resultant slot conflict. For example, in the
|
|
case above again, the first two slots are already reserved. If any
|
|
other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
|
|
snd-ens1371, it will be assigned to the third or later slot.
|
|
|
|
When a module name is given with '!', the slot will be given for any
|
|
modules but that name. For example, "slots=!snd-pcsp" will reserve
|
|
the first slot for any modules but snd-pcsp.
|
|
|
|
|
|
ALSA PCM devices to OSS devices mapping
|
|
=======================================
|
|
|
|
/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
|
|
/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
|
|
/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
|
|
/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
|
|
/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
|
|
/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
|
|
/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
|
|
/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
|
|
/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
|
|
|
|
The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
|
|
sound card number and second means device number. The ALSA devices
|
|
have either 'c' or 'p' suffix indicating the direction, capture and
|
|
playback, respectively.
|
|
|
|
Please note that the device mapping above may be varied via the module
|
|
options of snd-pcm-oss module.
|
|
|
|
|
|
Proc interfaces (/proc/asound)
|
|
==============================
|
|
|
|
/proc/asound/card#/pcm#[cp]/oss
|
|
-------------------------------
|
|
String "erase" - erase all additional information about OSS applications
|
|
String "<app_name> <fragments> <fragment_size> [<options>]"
|
|
|
|
<app_name> - name of application with (higher priority) or without path
|
|
<fragments> - number of fragments or zero if auto
|
|
<fragment_size> - size of fragment in bytes or zero if auto
|
|
<options> - optional parameters
|
|
- disable the application tries to open a pcm device for
|
|
this channel but does not want to use it.
|
|
(Cause a bug or mmap needs)
|
|
It's good for Quake etc...
|
|
- direct don't use plugins
|
|
- block force block mode (rvplayer)
|
|
- non-block force non-block mode
|
|
- whole-frag write only whole fragments (optimization affecting
|
|
playback only)
|
|
- no-silence do not fill silence ahead to avoid clicks
|
|
- buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
|
|
instead of filled blocks
|
|
|
|
Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
|
|
echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
|
|
echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
|
|
|
|
|
|
Early Buffer Allocation
|
|
=======================
|
|
|
|
Some drivers (e.g. hdsp) require the large contiguous buffers, and
|
|
sometimes it's too late to find such spaces when the driver module is
|
|
actually loaded due to memory fragmentation. You can pre-allocate the
|
|
PCM buffers by loading snd-page-alloc module and write commands to its
|
|
proc file in prior, for example, in the early boot stage like
|
|
/etc/init.d/*.local scripts.
|
|
|
|
Reading the proc file /proc/drivers/snd-page-alloc shows the current
|
|
usage of page allocation. In writing, you can send the following
|
|
commands to the snd-page-alloc driver:
|
|
|
|
- add VENDOR DEVICE MASK SIZE BUFFERS
|
|
|
|
VENDOR and DEVICE are PCI vendor and device IDs. They take
|
|
integer numbers (0x prefix is needed for the hex).
|
|
MASK is the PCI DMA mask. Pass 0 if not restricted.
|
|
SIZE is the size of each buffer to allocate. You can pass
|
|
k and m suffix for KB and MB. The max number is 16MB.
|
|
BUFFERS is the number of buffers to allocate. It must be greater
|
|
than 0. The max number is 4.
|
|
|
|
- erase
|
|
|
|
This will erase the all pre-allocated buffers which are not in
|
|
use.
