Comment 1 Gabriele Pohl 2017-11-19 15:32:10 UTC
hmmm, it seems the problem is located on other level than kernel.
I played around with application "volume-control" and saw that there were signals shown on the channel.

I then called "alsamixer -c0" following the advice given here:
https://fedoraproject.org/wiki/How_to_debug_sound_problems

And after that the sound appeared. I had changed nothing within the alsamixer app, only running it had solved the problem.

You may close the ticket but I would appreciate highly if I get an explanation what had happened here to avoid similiar problems in the future.

fyi,
Gabriele
