Advanced Linux Sound Architecture - Driver
==========================================
Configuration guide
Kernel Configuration
====================
To enable the ALSA support, at least you need to build the kernel with
the primary sound card support (CONFIG_SOUND). Since ALSA can emulate
the OSS, you don't have to choose any of the OSS/Free modules. Please
enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
PCM supports if you want to run the OSS application with the ALSA.
When you want to support the WaveTable functionality on some cards
such like SB Live!, you need to enable "Sequencer support"
(CONFIG_SND_SEQUENCER).
For getting more verbose debug messages, turn on "Verbose printk" and
"Debug" options. For checking the memory leaks, you can turn on
"Debug memory" option, too. "Debug detection" will put more
additional checks for the detection of cards.
Please note that all the ALSA ISA drivers support Linux isapnp API (if
the card supports). You don't need to configure the PnP via
isapnptools.
Module parameters
=================
A user can modify or set parameters at the load time of the module. If
the module supports more cards and you have got more than one card
of the same type, you may simply specify more values for the parameter,
delimited by commas.
Note that module option names were changed in 0.9.0rc4. The 'snd_'
prefix was removed.
Module snd
----------
The module snd is the ALSA core module, which is used by all ALSA
card drivers. This takes the global options for creating devices,
etc.
major - major # for sound driver
- default is 116
cards_limit
- specifies card limit # (1-8)
- good for kmod support if you do not want to search
for soundcards which are not installed in your system
device_mode
- specifies permission mask for dynamic sound device filesystem
- default value = 0666
- for example 'device_mode=0660'
device_gid
- specifies GID number for dynamic sound device filesystem
- default value = 0 (root)
device_uid
- specifies UID number for dynamic sound device filesystem
- default value = 0 (root)
Module snd-pcm-oss
------------------
The PCM OSS emulation module.
This module takes the options to 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.
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 the options to change the mapping of OSS
devices like 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)
Global parameters for top soundcard modules
-------------------------------------------
Each of top-level soundcard module takes some general options,
index - 0-7 - index (slot #) for soundcard
- if not set or -1, first free index (slot #) is assigned
id - user identification for card (up to 15 chars)
- default expression is 'card<index>' (for example card1)
- value is used for /proc/asound filesystem
- this value can be used by applications for identification
of card if user does not want identify card with index number
enable - enable card (only first card is enabled by default)

modprobe/kmod support
=====================
The modprobe program must know which modules are used for the
device major numbers.
Native ALSA devices have got default number 116. Thus a line like
'alias char-major-116 snd' must be added to /etc/modules.conf. If you have
compiled the ALSA driver with the OSS/Free emulation code, then you
will need to add lines as explained below:
The ALSA driver uses soundcore multiplexer for 2.2+ kernels and OSS compatible
devices. You should add line like 'alias char-major-14 soundcore'.
Example with OSS/Free emulation turned on:
----- /etc/modules.conf
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
----- /etc/modules.conf
After the main multiplexer is loaded, its code requests top-level soundcard
module. String 'snd-card-%i' is requested for native devices where %i is
soundcard number from zero to seven. String 'sound-slot-%i' is requested
for native devices where %i is slot number (for ALSA owner this means soundcard
number).
----- /etc/modules.conf
# ALSA portion
alias snd-card-0 snd-interwave
alias snd-card-1 snd-ens1371
# OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
----- /etc/modules.conf
We are finished at this point with the configuration for ALSA native devices,
but you may also need autoloading for ALSA's add-on OSS/Free emulation
modules. At this time only one module does not depend on any others, thus
must be loaded separately - snd-pcm-oss. String 'sound-service-%i-%i'
is requested for OSS/Free service where first %i means slot number
(e.g. card number) and second %i means service number.
----- /etc/modules.conf
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
# OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
----- /etc/modules.conf
A complete example for Gravis UltraSound PnP soundcard:
----- /etc/modules.conf
# ISA PnP support (don't use IRQs 9,10,11,12,13)
options isapnp isapnp_reserve_irq=9,10,11,12,13
# ALSA native device support
alias char-major-116 snd
options snd major=116 cards_limit=1
alias snd-card-0 snd-interwave
options snd-interwave index=0 id="GusPnP"
# OSS/Free setup
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
-----
A complete example if you want to use more soundcards in one machine
(the configuration below is for Sound Blaster 16 and Gravis UltraSound Classic):
----- /etc/modules.conf
# ISA PnP support (don't use IRQs 9,10,11,12,13)
# it's only an example to reserve some IRQs for another hardware
options isapnp isapnp_reserve_irq=9,10,11,12,13
# ALSA native device support
alias char-major-116 snd
options snd major=116 cards_limit=2
alias snd-card-0 snd-gusclassic
alias snd-card-1 snd-sb16
options snd-gusclassic index=0 id="Gus" \
port=0x220 irq=5 dma1=6 dma2=7
options snd-sb16 index=1 id="SB16"
# OSS/Free setup
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
-----
A complete example, two Gravis UltraSound Classic soundcards are installed
in the system:
----- /etc/modules.conf
# ALSA native device support
alias char-major-116 snd
options snd major=116 cards_limit=2
alias snd-card-0 snd-gusclassic
alias snd-card-1 snd-gusclassic
options snd-gusclassic index=0,1 id="Gus1","Gus2" \
port=0x220,0x240 irq=5,7 dma1=1,5 dma2=3,6
# OSS/Free setup
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
-----
If you want to autoclean your modules, you should put below line to your
/etc/crontab:
*/10 * * * * root /sbin/modprobe -rs snd-card-0 snd-card-1; /sbin/rmmod -as
You may also want to extend the soundcard list to follow your requirements.
ALSA PCM devices to OSS devices mapping
=======================================
/dev/snd/pcmC0D0 -> /dev/audio0 (/dev/audio) -> minor 4
/dev/snd/pcmC0D0 -> /dev/dsp0 (/dev/dsp) -> minor 3
/dev/snd/pcmC0D1 -> /dev/adsp0 (/dev/adsp) -> minor 12
/dev/snd/pcmC1D0 -> /dev/audio1 -> minor 4+16 = 20
/dev/snd/pcmC1D0 -> /dev/dsp1 -> minor 3+16 = 19
/dev/snd/pcmC1D1 -> /dev/adsp1 -> minor 12+16 = 28
/dev/snd/pcmC2D0 -> /dev/audio2 -> minor 4+32 = 36
/dev/snd/pcmC2D0 -> /dev/dsp2 -> minor 3+32 = 39
/dev/snd/pcmC2D1 -> /dev/adsp2 -> minor 12+32 = 44
The first number from /dev/snd/pcmC{X}D{Y} expression means soundcard number
and second means device number.
Please note that the device mapping above may be varied via the module
options of snd-pcm-oss module.
DEVFS support
=============
The ALSA driver fully supports the devfs extension.
You should add lines below to your devfsd.conf file:
LOOKUP snd MODLOAD ACTION snd
REGISTER ^sound/.* PERMISSIONS root.audio 660
REGISTER ^snd/.* PERMISSIONS root.audio 660
Warning: These lines assume that you have the audio group in your system.
Otherwise replace audio word with another group name (root for
example).
Proc interfaces (/proc/asound)
==============================
/proc/asound/card#/pcm#[cp]/oss
-------------------------------
String "erase" - erase all additional informations 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
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
