[streaming] distorted audio with lastest vls cvs

I have downloaded and installed the latest cvs for vls. Image quality is 
perfect but audio is horribly distorted. Could it be ffmpeg (using 
ffmpeg-0.4.7)?

i have tried various permutations in vls.cfg without success.

The VLC client I'm using plays video and audio files perfectly. The 
problem appears to be with vls.

Any help or suggestions would be appreciated.

Thanks,
Ollie
