Re: How to enable sound with Intel AC'97 on Sony VAIO GRX316G?

Bonjour Thomas,

 yes, that seems to be part of the solution. I have been using the ACPI
patch already, but now I also compiled the oss driver and have been a
bit more successful than before.

  So the current situation is:

        * Modules are not loaded automatically
Add i810_audio to /etc/modules. You may also use the sonypi modules which will allow you to use the jogdial (apt-get install sjog).
* but when loaded by hand * xmms does work and outputs that it used OSS 
        * kde sound does not work (when logging in it complains about
          /dev/dsp permision denied)
Add yourself to the audio group, or whatever group the /dev/dsp device belongs to. When modprobing i810_audio, if you did compile as modules OSS soud modules, your lsmod should read : 
i810_audio
soundcore
ac97_codec
Hope this helps. Note that my lsmod also reads i810_rng, since I compiled as a module the pseudo random number generator. I'm not sure it's related, but that's worth trying. Anyway, since you're using a vaio, you should use the sonypi driver (located in character devices). Being able to use the jogdial is great, and I think it also gives access to other sony specific features. 
        * gnome is quiet too

  What should I do next?

  What about alsa? I read that alsa is now the way to go, but oss. I
didn't find a alsa howto nor a package below /usr/doc. Where should I
look?

Cheers,
Mariano

I had exactly the same problem, on the same machine.
First of all, you should try OSS module i810_audio. If you card remains mute, or produces strange sounds as it did for me, you'll have to follow these steps: Update ACPI on your kernel. The reason why the sound card was not correctly working before is related to a IRQ sharing issue solved recently in the ACPI subsystem. the sound works perfectly with the OSS driver Intel ICH (i8xx) module named i810_audio. So you have to: 1. Patch your kernel with the latest version of ACPI, available from http://acpi.sourceforge.net 2. Compile a new kernel with ACPI enabled (I include it in the kernel, not as a module), and choose in the sound config: 
<M> Sound card support
...
<M> Intel ICH (i8xx)
...
<M> OSS Sound modules
3. Use the new kernel.

I can provide my .config, if it helps,

Thomas

Hi, 
 lspci -vv gives the following output:

 I don't find a Kernel Module with a similar name?! What do I need to
look for? Would the discovery of the right module be everything needed
to get the sound up and running on woody or do I need anything else?

 Just in case that is interesting?!hamlet:/home/mkamp# lsmod
