well, on my machine gcc3.1 kernel/module are working quite well. i guess the problem is combination of kernel/modules compiled with different gcc versions. you need to compile both kernel and _all_ modules with the same compiler. > Now on to *other* problems... > > I'm not sure how to interpret many of the mixer channels in > alsamixer, but I'm fairly sure that "Master" is supposed to > control *everything.* Apparently "Master" only affects the > front channel... yes. confusingly it's named so. the Master is the master of AC97 channels, i.e. front speakers. other speakers are not routed via ac97, so they are not affected. > When I'm playing a DVD (via xine+4channel) or an mp3 (via > xmms+alsa plugin), front channels get controlled by "Wave", and > rear channels get controlled by "Wave Surround".
