Does the Handbook mention to check your mixer settings? Make sure to try that. Use any "simple-enough" media player to play some MP3, OGG or WAV file (e. g. per xmms or whatever comes with your preferred desktop environment). Make sure you have "vol" and "pcm" up. % mixer Mixer vol is currently set to 100:100 <--- This. Mixer pcm is currently set to 84:84 <--- And this. Mixer line is currently set to 75:75 Mixer mic is currently set to 0:0 Mixer cd is currently set to 75:75 <--- This too. Mixer rec is currently set to 75:75 Mixer igain is currently set to 0:0 Mixer monitor is currently set to 75:75 Recording source: mic The problem regarding audio CDs seems to be quite "modern". I also cannot play them anymore (but I don't have that special wire installed at the moment). Audio is VIA HDA. > So, um, I am grasping for ideas here on how I can debug this problem furher.
