redhat9+AC'97(intel8x0) 驱动?
我按照以下声卡驱动做完以后,出现了这样的信息:[
cat WARNING
WARNING!!! The mixer channels for the ALSA driver are muted by default!!!
**************************************************************************
You would use some ALSA or OSS mixer to set the appropriate volume.

测试还是没有声音,还有其他的办法吗?
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.
Module option name change after 0.9.0rc3
========================================
Note that module option names were changed in 0.9.0rc4. The 'snd_' prefix
was removed. You may use script in utils directory (module-options) to
convert your older /etc/modules.conf to newer one.
Quick install
=============
1) You must have full configured source for the Linux kernel which you
want to use for the ALSA drivers. Note that ALSA drivers are part
of the kernel, so there is necessary to resolve all symbol dependencies
between the used kernel and ALSA driver code. Partly installed kernels
(for example from distributor makers) can be unuseable for this action.
2) You must turn on sound support (soundcore module).
3) 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.
If you have kernel source code in another directory than /usr/src/linux,
use --with-kernel=<kernel_directory>.
Example: ./configure --with-isapnp=yes --with-debug=full
4) Run 'make install'.
5) Run the './snddevices' script to create new sound devices in /dev directory.
Skip this step, if you have a kernel with the DEVFS support.
6) Edit your /etc/modules.conf (see the kmod support section below).
7) Run 'modprobe snd-xxxx' where xxxx 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 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.
Compilation from CVS sources
============================
You need GNU packages autoconf and automake installed in your system
to compile CVS sources of alsa-driver package.
For compilation you can use these commands:
make ALSAKERNELDIR=../alsa-kernel all-deps
(if the alsa-kernel-dir is really there)
aclocal
autoconf
./configure
make dep
make
The included cvscompile script does this job for you.
Note: Some automake packages have missing aclocal program. Use newer version
in the case.
Cross-compiling
===============
Use '--with-cross=prefix' parameter for the configure script.
Example:
'./configure --with-cross=arm-linux- --with-kernel=/home/ipaq/kernel/linux'.

Additional Modules
==================
Module snd-mixart
-----------------
Module for Digigram miXart8 soundcards.
Module supports multiple cards.
Note: One miXart8 board will be represented as 4 alsa cards.
See doc/MIXART.txt for details.
Module snd-msnd-pinnacle
------------------------
Module for Turtle Beach MultiSound Pinnacle/Fiji soundcards.
io - Port # for pinnacle/fiji card
irq - IRQ # for pinnalce/fiji card
mem - Memory address (0xb0000, 0xc8000, 0xd0000, 0xd8000,
0xe0000 or 0xe8000)
write_ndelay - enable write ndelay
calibrate_signal - calibrate signal (?)
Module supports only one card.
Module snd-pdplus
-----------------
Module for Sek'D/Marian Prodif Plus soundcards.
silent_exit - Do not reset when driver is unloaded.
init_adat - Initialise the card in ADAT mode (instead of in digital stereo).
Module supports up to 8 cards.
Module snd-serialmidi
---------------------
Module for generic serial MIDI adapters.
sdev - Device file string for serial device
(default = "/dev/ttyS0")
speed - Speed in bauds. (9600,19200,38400,57600,115200)
(default = 38400)
adaptor - Type of adaptor.

3 = MS-124W M/B
Module supports up to 8 cards. alsa安装好后默认是静音的。
如果你在x下，那么直接调整那个小喇叭就行了。如果是在字符终端下，可以输入：aumix命令，调用rh自带的一个mixer进行调整。 oss也挺好装的
就是声音怪怪的..........
