After a fresh boot sound works for a while (around 1min) and then stops.

doing a suspend, sound works again, and stops.

Find attached the a script used to read out information while sound was working and after it stopped

[MD4 (bruno-mueller)]

The only change in the output from alsa-info.sh was
Power: setting=D0, actual=D0
changed to
Power: setting=D3, actual=D3

any idea
