Hi,
I read your post, which confirmed my suspicions about my own DWA-142. Ever since I upgraded to 802.11n (including that adapter) then my audio has experienced the exact symptoms that you describe. I've used two different sound cards (including a fairly high-end Audigy 2 card) and different playback programs. Disabling the device in my system did make the problem go away.
So...I suppose we just have to wait for updated drivers?
Any progress on your end?
