No sound on video files.

I just downloaded avast today, and now sound doesn’t work on video files for VLC media player, and WMV types don’t work at all.
This could be totally unrelated to the avast program, but these symptoms mimic the sound stoppage in windows safe mode so it may have something to do with a security feature of the program. Anyone had a similar problem, and how did you fix it?

Strange… Does avast autosandbox any sound driver or necessary file?

Iv installed avast and the latest VLC 2.0.1 on many systems with no issues at all, have you tried updating your audio drivers? maybe reinstalling VLC Player might help.
