Title:
no sound after resume
Status in Ubuntu:
Incomplete
Status in linux package in Ubuntu:
Incomplete
Bug description:
Kubuntu 20.04.
Sound via HDMI
Sometimes after resume sound output is disabled. I cannot determine
what causes it but it occurs about 20% of the time. My sound output
is via HDMI and it's usual for the HDMI device to be asleep when the
computer resumes. Normally as the monitor wakes the sound is
restored.
According to the GUI tools the sound output is set to HDMI and I can
restore it by selecting any other device and then reselecting the HDMI
device or I can issue pulseaudio -k
