I followed the guidlines for sound setup with alsa, and after rebooting, the kernel panics and my system fails to load. Although I should have, I did not write down the error message and I prefer to avoid hanging my machine up like that. I also tried, the kernel configuration found at ppckernel.org for titanium powerbooks. Interestingly, the config found at ppckernel.org has CONFIG_DMASOUND_PMAC=m, a setting that was said to be left out in the gentoo ppc FAQ. Is this information outdated? Does anyone have sound working on this machine or something similar? If so, would you mind helping me out?

You probably compiled the sound support into your kernel, but didn't compile in i2C support. Make sure you have i2C support compiled into your kernel, and if that doesn't fix the problem, post the panic message. The FAQ is up to date, the dmasound_pmac module is for OSS only (as the FAQ says) and you should not have both enabled.

I compiled my kernel with ic2 in addition to following the alsa setup guideline in the ppc FAQ. The system rebooted without a kernel panic. Thanks. I am attempting to play an .mp3 file with xmms and I get the following message:

Couldn't open audio
Please check that:
-Your sound card is configured properly
-You have the correct ouput plugin selected.
-No other program is blocking the sound card

I went into prefrences of xmms, looked in I/O plugins, and saw libcdread.so, libmpg123.so, and libvorbis.so. Should libmpg.so be all I need to play mp3's? Also, I went to mpg123's homepage via link from www.gentoo-portage.com and it said that there are some "serious security" risks. Ok... should I get rid of libmpg123.so? If so, how? Can I play mp3's some other way or is it necessary for me to convert my music to another format?

Thank you. I just tried out an audio cd through xmms and the volume and sound quality were good. I think that's the first sound, aside from a beep, I've ever heard through a linux system.

One thing though, I had to run
Code:
xmms /dev/cdrom
as root though. Do I have to add myself to the cdrom group?
