Description changed to:
    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" (or "Main" to prevent confusion with
    old settings) - 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.
