Title:
Popping/crackling noise when sound card wakes from powersaving
Status in linux package in Ubuntu:
Incomplete
Bug description:
I could not find an existing report on this.
When Ubuntu 20.04 does powersaving, the audio card powers down.
When the card powers up again, it emits a short annoying popping/crackling
noise, then audio plays just fine.
The workaround is to disable power-saving for the audio card, by
adding
options snd_hda_intel power_save=0 power_save_controller=N
to a file in /etc/modprobe.d/alsa-intel-no-powersave.conf
and then reboot.
