I just got a new laptop and when I try to play DVD's, I only get video, not audio. I get all other audio, just not from DVDs. This happens with all dvd's in both my external DVD writer and the internal player. I've tried playing multiple DVDs in Windows Media Player and InterActual and still no audio, but when I encode or rip a dvd using Handbrake or DVDFab, the audio is there. I'm running Windows XP. Anyone have ideas on how to fix this one?
