Comment 4 for bug 192382

Confirmed.
(also Fujitsu-Siemens Amilo Pi 1505, Kubuntu Hardy Heron with all recent updates)

Some additional information:

   $ amixer
amixer: Mixer default load error: No such file or directory

kmix only shows Master, Microphone, CD, PCM and Digital, all in the "output"-tab. There are no more channels available.
kmix shows the soundchip as Realtek ALC861.
Muting and moving of the sliders is possible but has got no effect.
