This has happened to me a few times in the past; more frequently since I started using Norton Internet Security. I previously used System Restore as a solution, but I hope there’s a better way to fix and perhaps prevent this.
It seems to happen when I have too many processes or programs running - basically if I overwork my computer while I have a video playing. The audio will start lagging (it sounds choppy and awful). But this isn’t just the video buffering or loading slowly; the sound lag is now permanent.
Even when I close everything else and bring the CPU usage down very low (right now it’s at 20% with a youtube video and some basic software running; nothing that has ever caused the problem in the first place), the lag persists.
I’m on Windows XP and have tried only the basics (since I don’t know what I’m doing):
Restarting the computer
Turning off hardware acceleration
Reinstalling / updating flash player
No luck. If you could help me out, that would be excellent. Thanks so much!
