Thanks, works all well until here. It still doesn't record anything. I guess 
it's either the soundcard or I'm too stupid for it  :-(

Is it really /dev/dsp0?
Below is the output from ecasound, maybe it helps (I installed from source 
with debug symbols). The file test.wav is there after running ecasound, but 
there's only silence in it.

Regards,
Daniela
