Dell :: Audio Pop, Skipping, Chop

I have a XPS1530 t7700, 2gb ram, 160gb HD. Vista Premium 32bit.

It's the common studder, pop, skip, chop whatever you wanna call it when playing music or any audio while the internet connection is active. Using winamp, WMP, youtube, they all skip. Here is what i've come to discover, after trying eveyone's solutions, some working for others but all not working for me.

-Skippy audio happens ONLY when the internet connection is active (Intel Wireless 4965AGN), disable the connection and audio plays perfectly. Open a heavy bandwidth webpage or torrent program and the sound gets much worse. and Yes, drivers are fully updated 7/8/08

-Sigmatel HD audio codec is NOT the problem. I've completly uninstalled sigmatel and still have issues even with Microsofts generic HD sound drivers. currently using sigmatel driver R171789 for the Stereo Mix recording function. Sigmatel drivers fully updated as well.

-Disabling the wireless "A" band or both A and B bands doesnt do anything to fix the skipping.

-Installed the popular LG soundcard codec in place of sigmatel, and that did nothing.

-Called dell and they just think something is faulty and wanna start replacing parts. Thats doesnt work either, Ive read countless threads about dell replacing parts to fix this issue and it's just a waste of time.

Is there any hope of fixing this skippy audio? mine skips soo bad where i cant even listen to music without wanting to smash my xps.
