I have exactly the same problem and the only fix I use is not to play
DVD's or CD's on the computer.
There is nothing wrong with them, I've played them on other devices.
I can play DVD games with no sound problems.
Movies are an issue and playing cds in itunes or anything gives exactly the same problems as the poster of this topic has.
Its been a few years, but I hope someone has some answers. I would
like to play CD and movies on my pc (xp)!
It use to be fine and then suddenly I have no idea. Dell wants me to buy new
dvd software, but I doubt that will fix the problem. I've tried other players. Nothing and if itunes can play them either then I dunno. I have to import and then play.
Also it seems to slow down the pc. It also affects webpages, become slow because sound issues. e.g on Youtube...sound is terrible when I have a CD in my combo drive.
Anyone managed to work this out?
