apport information
** Tags added: apport-collected apport-hook-error
** Description changed:
Expected behaviour:
When running Ubuntu 21.04 on desktop hardware any active USB audio
devices should not be suspended while playing/recording audio.
Actual behaviour:
When running Ubuntu 21.04 on desktop hardware active USB audio devices
that are playing/recording audio are suspended after a few seconds.
This upstream bug appears relevant and seems to lay the blame elsewhere,
perhaps the kernel.
