I looked at all the stuff Chris Pollock wrote in that thread and the solution
seems not to apply to me...

But my system responds differently:

~$ sudo fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  bosse      1607 F.... pulseaudio
                     bosse      5711 F.... pulseaudio
/dev/snd/controlC1:  bosse      1607 F.... pulseaudio
                     bosse      5711 F.... pulseaudio

So there is no timidity but audio is non-working the same way as with Chris...

Now I also rebooted the system but no change. Audio seems to be disabled.
During reboot I looked at the BIOS settings and found that the audio is enabled
on that level.
