Panel volume control no longer working after 2.6->2.8



Hi list,

after my upgrade from 2.6 to 2.8.0 the volume control in the panel does no longer work. If i operate the slider, it immediately snaps back to zero when released. If i select "Open volume control" i get "Sorry, no mixer elements and/or devices found". Permissions on /dev/snd and /dev/sound are ok:

Also, alsamixer works fine and i can play mp3 files with xmms.

Any ideas?
