Affects: gnome-applets (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Volume keys on my multimedia keyboard seem to control only Master track
in ALSA, so for example, when I press mute key, only front speakers are
silenced, while rear speakers play at the same volume. Contrary to its
name, Master track controls volume of only front speakers; PCM controls
volume of all speakers. Volume Control applet also controls Master by
default, but its possible to change it in its preferences.

In my opinion multimedia keys should control ALSA track set in
preferences of Volume Control applet and it should be PCM by default.

Also in ALSA: "Master" should be renamed to "Front", "Surround" to
"Rear" and "PCM" to "Master" - it appears that current names are
confusing not only for users, but also for developers. Unfortunately it
requirers acceptance and cooperation with upstream ALSA developers. This
is also bug #13151.


Hardware:
- Logitech multimedia keyboard (its name varies from region to region - it is the one that comes with MX700 mouse; I am using Logitech Cordless Desktop Pro model in keyboard layout controls);
- nVidia nForce2 SoundStorm (on Abit NF7-S);
- Creative Inspire 5300 5.1 analog speakers.
