sound problems on 2008.08

[Michael Kluge]

Hi,

I am running 2008.08 and the phone does not make any sound on an incomming 
call or when I get a SMS or an entry from my calendar should pop up. I can 
hear music with openmoko-mediaplayer. The profile in the settings is set  
to "ring and vibrate". "ring only" does not give any sound either.

Any suggestions what could be wrong? I could not found a mixer app for the 
qtopia stuff. Is there any?
