Volume control broken after Gnome 2.6 Upgrade

[josh <jbuhl_nospam@gmx.de>]

After upgrading to Gnome 2.6 in unstable, the volume control applet no
longer works. if I click on the slider, it just jumps back to the
original position. If I open the volume applet's preferences dialog, the 
text area supposedly containing the available audio channels is empty.

If I select the volume controls from the gnome taskbar menu
applications->multimedia->volume controls (which launches
gnome-volume-control), then an error message appears stating, " Sorry,
no mixer elements and/or devices found" . The same thing happens if I
start gnome-volume-control directly from a terminal and no other error
messages appear in the terminal.

*However*, the volume slider on xmms works fine, as does the
gnome-alsamixer.


Anybody else experiencing this, or know what's causing it?


Thanks

Josh
