apport information ** Description changed:
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.
