Audio is not working in the Parallels 5

[omela]

Hi all
I have used bootcamp (Vista 32) with Parallels 4 and everything was ok
But after upgrading to Parellels 5 my audio stopped working
Reinstalling Parallels didn't help
In bootcamp al is working fine.

Did you install the updated virtual machine tools ("Parallels tools")?
