Title:
alsa force-reload needed to fix my sound after upgrade to 20.04
Status in Ubuntu MATE:
New
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
After upgrading from Ubuntu Mate 18.04 LTS to Ubuntu Mate 20.04 LTS
"sudo alsa force-reload" is needed to fix my sound.
I upgraded yesterday (23rd) before the official announcements of 20.04
LTS. Using "do-release-upgrade -d".
I'm not sure yet how often I have to run "sudo alsa force-reload".
When I have no sound a reboot is not a guranteed fix although it
worked once.
Booting into a Ubuntu Desktop 20.04 LTS gets working sounds each time
I tried.
Audio: Device-1: Intel 6 Series/C200 Series Family High Definition Audio
driver: snd_hda_intel
