I would like to record via SPDIF in and have no idea why it doesn't
work. Maybe it is something trivial. It could be that my
asound.state is not correct or I don't use the right syntax when
recording. I tried different apps like audacity, qarecord, ecasound
and others. Analogue playback works.
Please tell me what to do exactly, especiall which syntax I should
try for recording.
Below there is some info of my system.
