When playing quicktime movies and playing games, the sound is delayed a bit. No choppyness or bad quality, just comes after the actual action takes place. Does this in older games, though Q3 arena demo seems to be fine. Anyone know whats wrong?

Apple just posted the Mac OS 9 Audio Update 1.1, today. You might give that a try.

Did that, but the delay is still around in some programs and clearly in quicktime movie playback

I was experiencing the same problem on my iMac DV. It went away when I disabled voice recognition, text to speech and all the Microsoft garbage in the extensions folder. So it must be an extension conflict. Sorry I am not being more specific, I just disabled everything in one chunk. If you really want to know the culprit try Conflict Catcher. Hope this helps.

I noticed a delay between Audio Input and Output on my DV SE. Apparently this is due to the new digital audio circuitry on these machines, in combination with some flaws in the current Sound Manager. QuickTime 4.1 and/or OS 9.1 will hopefully fix this.

Also, turning off VM helps in some cases...
