Advanced Linux Sound Architecture - Driver
==========================================
Installation guide
The ALSA driver replaces the OSS/Free driver. The OSS/Free driver is
present in current Linux kernels (2.2). Since version 0.4.0, ALSA has
supported only 2.2+ kernels. The 2.0 kernels are no longer supported. You
must compile the kernel with sound support (you do not need to select
any of the other sound modules apart from sound support).
Before installing this driver, it will be helpful to read carefully
the documentation for insmod, modprobe, kmod and for the isapnp
module if you have an ISA PnP soundcard.
Quick install
=============
1) You must turn on sound support (soundcore module).
2) Run './configure' script.
If you have ISA Plug & Play soundcard, use --with-isapnp=yes switch.
If you want sequencer support, use --with-sequencer=yes switch.
If you do not want OSS/Free emulation, use --with-oss=no switch.
If you want turn on debug mode use --with-debug=full switch.
If you want debug soundcard detection try --with-debug=detect switch.
Example: ./configure --with-isapnp=yes --with-debug=full
3) Run 'make install'.
4) Run the './snddevices' script to create new sound devices in /dev directory.
Skip this step, if you have a kernel with the DEVFS support.
5) Edit your /etc/modules.conf (see the kmod support section below).
6) Run 'modprobe snd-card' where the card is the name of your card.
Note: If you have a ISA PnP soundcard you need to first run the isapnp
program from isapnptools package to initialize your
soundcard. You can also use the native ISA PnP support by
using the --with-isapnp=yes configuration switch, in which
case you do not need the isapnptools package.
You can also look at the utils/alsasound file. This script is designed for
the RedHat distribution, but it can be used with other distributions which
use System V style rc init scripts.
Note: All mixer channels are muted by default. You must use a native
or OSS mixer program to unmute appropriate channels (for example a
mixer from the alsa-utils package).
Note: This document notices the /etc/modules.conf file. Many current
distributions uses the old /etc/conf.modules file. Both names are
valid.
Driver cannot be activated?
===========================
1) You can check your soundcard setup again and read this install file
(module parameters) carefully.
2) If you have got ISA PnP soundcard:
- native ISA PnP support: is your setup in /proc/isapnp.conf correct?
- isapnptools: is configuration on isapnp.conf same as for the driver?
3) The driver is not still working: remake driver with:
./configure --with-debug=detect; make clean; make
Reinsert new driver modules to kernel and look to /var/log/messages if
there are some messages. If these messages do not help you, please
create a new ticket in our bug reporting system.

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.
Module snd.o
------------
snd_major - major # for sound driver
- default is 116
snd_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
snd_device_mode
- specifies permission mask for dynamic sound device filesystem
- default value = 0666
- for example 'snd_device_mode=0660'
snd_device_gid
- specifies GID number for dynamic sound device filesystem
- default value = 0 (root)

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 for 2.2 kernel (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 toplevel 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-card-interwave
alias snd-card-1 snd-card-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.o. 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
options isapnp isapnp_reserve_irq=9,10,11,12,13
# ALSA native device support
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
alias snd-card-0 snd-card-interwave
options snd-card-interwave snd_index=0 snd_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
options isapnp isapnp_reserve_irq=9,10,11,12,13
# ALSA native device support
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=2
alias snd-card-0 snd-card-gusclassic
alias snd-card-1 snd-card-sb16
options snd-card-gusclassic snd_index=0 snd_id="Gus" \
snd_port=0x220 snd_irq=5 snd_dma1=6 snd_dma2=7
options snd-card-sb16 snd_index=1 snd_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 snd_major=116 snd_cards_limit=2
alias snd-card-0 snd-card-gusclassic
alias snd-card-1 snd-card-gusclassic
options snd-card-gusclassic snd_index=0,1 snd_id="Gus1","Gus2" \
snd_port=0x220,0x240 snd_irq=5,7 snd_dma1=1,5 snd_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.
DEVFS support
=============
The ALSA driver fully supports the devfs extension. You should add lines
below to your devfsd.conf file:
LOOKUP snd EXECUTE /sbin/modprobe snd
REGISTER sound/.* PERMISSIONS root.audio 660
REGISTER snd/.* PERMISSIONS root.audio 660
Proc interfaces (/proc/asound)
==============================
/proc/asound/#card#/pcm#o
-------------------------
String "Playback erase" - erase all additional informations about OSS applications
String "Playback <app_name> <fragments> <fragment_size> [<options>]"
String "Capture erase" - erase all additional informations about OSS applications
String "Capture <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...
- block - force block mode (rvplayer)
- non-block - force non-block mode
Example: echo "Playback x11amp 128 16384" > /proc/asound/0/pcmD0o
echo "Capture squake 0 0 disable" > /proc/asound/0/pcmD0o
echo "Playback rvplayer 0 0 block" > /proc/asound/0/pcmD0o
