Uggh! Now I have the same problem again.
Really puzzling! The sound came back on when I checked the box in VLC preferences --> audio, for "use S/PDIF"
After listening for about half an hour, with everything working fine, suddenly now the audio is gone again. The picture plays fine but no sound.
Paulger, I did check if my version is up-to-date. I'm on a mac, and have version 2.0.5 which my computer's "check for updates" program says is the most recent one.
If anyone has any more ideas to try, I'd appreciate it greatly!!!
