Public bug reported:
On a stock installation, the headphone volume is stuck low and cannot be
adjusted.
It turns out that PulseAudio mutes the output "Speaker+LO" when
headphones are inserted, which is against what we want.
The problem can be fixed by modifying the section "Element Speaker+LO"
in /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf
as follows:
Before:
[Element Speaker+LO]
switch = off
volume = off
After:
[Element Speaker+LO]
switch = on
volume = merge
However, I suppose committing this change as-is might break some other
machines. Is there a way to make a machine-specific exception for this
laptop?
