Re: sound card problems
Ah yes, you're probably right, Hendrik.
And just one more quick hint. With 'vlc' playing music, you can switch on-the-fly (while playing music) between the available devices by the 'Audio' -> 'Device' top menu. Just to check which card or chip works, or not.
Another issue i've seen with older cards was Open Sound System (oss) packages installed somehow prevented the correct ALSA module to load. At least that's my best guess, when it worked again after i deinstalled anything oss related (including oss4-base), but i might have changed more in the process.
