Comment 2 for bug 177409

The issue was with the static declaration of 3 stereo audio tracks. The volume status bar and control panel apps have now been completely upgraded to do things dynamically. Changes are in 0.26.

  * Major upgrades to the Sound/Mixer applet
    The applet now dynamically adds tabs for each sound element found
    and also controls within each tab for each channel found
    Channels with no mute switch have the mute button removed
    Channels with no volume ctrl have the slider removed
    Elements/channels with neither are not given a notebook tab
    The volume range sliders now use the hardware values instead of 0-100
    The libvolumecontrol interface was expanded and made easier to use
    By default any element with PCM, Wave, or Master in its name is
        controlled by the volume status bar applet
