Vista - Audio Delay / Lag Issues.

I'm using the onboard audio on my P6T Deluxe Mobo. I've had my new build for a few weeks now and this is my first build. Everthing is perfect and it runs like a charm. The only issue I have is with the sound. It tends to lag for a few seconds after playing back audio.

Example: I'll be playing a song on (tried both) Winamp or Windows Media Player and after 1 minute or so, it will lag for like 2 - 5 seconds then go back to normal. It's very annoying that this happens every song after a few minutes of audio playback. I can't really notice the lag when I play games.

What I did: Updated all drivers from ASUS (Still need to flash my mobo) as far as sound goes. But still no results! It still lags...

Any help will be great!

Thanks

Bump.
