Bug Description
[Impact]
Fail to run '/usr/sbin/alsactl restore' on the HDA-Intel machines, this
results in the failure on setting the init mixer values for HDA sound
card, and users experience the mute of audio after installing the 20.10.
[Fix]
Backport a patch from the latest alsa-lib (v1.2.3+)
[Test]
Without the patched alsa-lib, rm ~/.config/
sudo sh -c "echo b > /proc/sysrq-
muted.
Install the patched alsa-lib, rm ~/.config/
sudo sh -c "echo b > /proc/sysrq-
not muted.
[Regression Potential]
This could make the ucm audio fail to initialize, but this possibility is
very low, since this patch is from upstream, and I tested on a ucm based
machine, the audio is good.
On boot into the live session - or on first install the sound level is muted.
I have to use GNOME Control Center - Sounds to change to an appropriate level. Once changed the level chosen is correctly retained between reboots.
This appears to be a regression from 20.04 where the sound level was set to - I guess - 80% on the live-session/first install
