Re: sound problem ibook g4
I have been having this same trouble of no working sound for months.
So recently, after installing the latest kernel from sid and seeing no benefit, I thought based upon web posting of other people that the problem was the older released alsa drivers. So I went directly to the alsa web site and installed the latest alsa-drivers. It has had no effect. same sound output on the installed debian. Thus I don't think that we can attribute the problem to the new alsa drivers which are newer than the sid alsa version.
I did what you said to do. rmmod the snd-powermac and did the install of the kernel you asked for. Now I get the following:
snd_aoa_codec_tas 13459 0

however now when i try to play an mp3 file:
