Hi all,

Since I reformatted my hard drive and reinstalled Windows XP a few weeks ago, sound playback is choppy. If you play a song there are skips and pops, and if another program is running or opening, it gets much worse. iTunes seems to be worst but WMP and other players are affected too. Before I reinstalled XP, sound playback was very consistent, even with loads of programs running at once.

In Device Manager under "Sound, video and game controllers", I have:
Vinyl AC'97 Codec Combo Driver (WDM)
as well as
Legacy Audio Drivers
and
Audio Codecs

My chipset is:
North Bridge: Via VT8372 ProSavage DDR KN266
South Bridge: Via VT8233/8235

I have DirectX 9.0c, Service Pack 2 and all available Windows Updates.

As suggested on some other forums, I tried installing the Via Hyperion 4in1 drivers, then installing the sound drives. I have tried with the "Vinyl AC'97 Audio Controller Driver 6.00a (5/26/2005)" and the "VIA Onboard Sound Drivers". The problem was still the same, though.

I also tried uninstalling the device from Device Manager, restarting and letting Windows do its "Found New Hardware" thing. It found the same driver and the problem still remained the same.

Can anyone help me?

I've had very similar problems to these, but on my system ONLY iTunes and Quicktime are affected. WMP runs fine, but after formatting my hard drive iTunes got really choppy (Quicktime too). Does anyone know what the problem is? Or how to fix it?
