US 11.10. - No audio out

[Ralf Mardorf]

Pulseaudio is replaced by a dummy package, this always worked for my
Debian testing and is still working for my Arch Linux and it seemed to
be ok for US 11.10 to. But now I tried to listen to a Youtube song. No
audio out. I rebooted and was able to listen to one song, for the next
song again, no audio out. I rebooted again, but still no audio out.
