Well folks, I've been chuggin away at this iBook of mine for quite some time now, but I just can't seem to get this sound issue . When I emerge the alsa driver i get this error:
Code:
 * Checking for suitable kernel configuration options
 *   ALSA is already compiled into the kernel.
 *   Some of the drivers you selected require PNP in your kernel (interwave interwave-stb).  Either enable PNP in your kernel or trim which drivers get compiled using ALSA_CARDS in /etc/make.conf.
 * Please check to make sure these options are set correctly.
 * Once you have satisfied these options, please try merging
 * this package again.


Now there are a few questions I have:
1. On This page where it explains how to get sound working it says to enable PowerMac DMA sound support, however below that it says to have it tuned off or the alsa module will not load. Well, it is in my kernel, so should it stay or be removed? - I tried both removing it and just having it in as a module (changing nothing else in my kernel config) and i would get kernel panics at boot:( My system will only boot with this option built in.

2. Where in menuconfig would this "PNP" be that apparently needs to be enabeled?

3. Any other help?

I very much appreciate any help.

If you use a 2.6 kernel, then the drivers are included in the kernel sources.

If you want to use OSS drivers, then activate PowerMac DMA sound support,
disable ALSA, enable OSS, but under OSS you have to disable all the other drivers.

If you want to use the ALSA drivers, then disable PowerMac DMA sound support,
disable OSS, enable ALSA, and under ALSA choose the support for Apple computers,
and disable all the other drivers.
Then you should also emerge alsa-headers and alsa-lib.

If you do that, then the message about PNP should disappear...
and you sound should hopefully work :)
