Title:
"Master Mono" (actually LFE) is not controlled by default
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
On my laptop, Alsa Mixer and the gnome panel volume control applet
show two channels which both control different subsets of the laptop's
built-in speakers; Master and "Master Mono". I think Master controls
the smaller speakers and "Master Mono" the larger/bass speakers.
By default, the gnome volume control applet (and also the dedicated
volume keys on my laptop) only control Master, and ignore "Master
Mono". This leaves "Master Mono" set at a high volume all the time,
which sounds crap.
To WAR this issue, in Gnome, I go to System -> Preferences -> Sound, and
change the selection in the list box under "Default Mixer Tracks" to include
both Master and "Master Mono". Now the volume applet and volume keys
control both channels, which works great.
This should be automatic (part of the volume control applet, or the
driver, or ...); I shouldn't have to configure this myself.
Attaching output from "amixer -c0".
