By 'this problem' do you mean whatever the registry key thing is meant to fix or do you mean VLC player having no sound? Because I'm dead certain VLC player is not playing sound.
Okay, deleting that folder fixed it, thanks very much.
My VLC player's sound cut out in the middle of a Gilmore Girls episode. alphie's solution looks Vista-specific; I certainly can't figure out how to apply it to an XP machine. Granted it would probably help if I knew what a registry key is and how to get at it. Somebody willing to walk me through fix...
