Audio Cross talk when charging and playing music

[Puffaloes]

I'm wondering if I have a faulty device of if other people have experienced this problem. When I charge the Mytouch and play music from the stock program there is a constant obnoxious noise, as if there is poor insulation on the internal wires causing cross talk. Once the charger is unplugged the noise ceases. I Drive a lot for work and i am music lover so this problem is causing me some serious grief. Anyone experiencing the same issue?
