For some odd reason I'm having trouble playing any sort of sound from the internet, whether it's RealPlayer, Windows Media Player or Quicktime files. It had been working fine earlier...until I loaded a DivX movie file into RealPlayer. I later deleted the file and realized that Realplayer was no longer working, as neither was WMP. It's extremely annoying! The streams, sounds, and movies all actually load and play, but no sound ever comes out, although iTunes works fine as does iTunes radio. What's going on?! Could something from the DivX movie file have messed with my sound card? Could it be some random plugin setting that got messed up? The problem's the same in IE, Firefox, and Safari. I tried reinstalling RealPlayer and restarting my comp, and nothing has helped. Please help!
