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

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
