如果你的世界里没有声音,你会是什默感觉呢..........

SKYDAU

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'.
