z3ttacht, are you still working on this issue? I just received another 
bugreport:

# amixer set Front unmute
amixer: Invalid command!

I'd like to fix the aumix/alsamixer issues for the upcoming release.

Alex/z3ttacht: Please let me know the current state regarding this issue. I 
haven't heard anything from you even though I pinged you several times. If you 
don't react within the next ~2 weeks I plan to work on this issue on my own.

JFTR: re-titling the bugreport and making it a release-stopper issue.

regards,
