Title:
Volume either 0 or 100% on Lenovo X1 Carbon G7
Status in gnome-shell package in Ubuntu:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
Volume increasing or decreasing doesn't work.
I can only toggle sound on (= 100%) and off (= 0%).
What I found out is that the Master channel seems to have no effect
for volume adjustments, but the PCM channel does. If the sound is
muted, PCM is set to 0 and therefore the sound is toggled off, but
when I increase the sound a bit, PCM jumps straight to 100, causing
the speakers to be very load.
I have attached alsa-info output.
System environment:
Pop!_OS 19.10
Release: 19.10
Alsa-Version:
alsa-base: 1.0.25
