Hi
I have the same problem, I have the realtek sound and whenever I am playing any music, video through media player or itunes and using the net (even if its only 10kb/s) it will distort and pop the sound.
Did you find a solution or does anybody know of one.
I have tried going back to the original windows driver and it worked for about an hour, also when I first installed vista it worked for a while.
Thanks in advance
Yarno
