Vista DVD playback on Hyperthreading CPU
Found frustrating situation. I have a box with Intel Pentium 4
Hyperthreading CPU, 2 audio cards (one is with the driver from Vista).
During DVD playback (tried 3 DVD players + Windows Media Player) I've been
hearing clicks that occurs in headphones or in speakers. For both audio
cards. It was when hyperthreading was on. When I have turned it off the
effect went away and it seemed more or less ok. Under XP everything was
fine. CD playback is fine for both XP and Vista.
