My XPS13 seems to have a quiet buzz when scrolling on the touch pad or touch screen. If there is any audio playing through the speakers then this causing interference and crackling through the speakers. If I stop scrolling the crackling stops. So it would seem there is some electrical interference on the board somewhere, possibly in relation to the toucpad/touch screen.

I have read various instance of people having buzzing and coil whine and similar problems on their XPS13. Can anyone confirm what the fix was, was a part replaced, motherboard/touchpad etc?

I have logged it with Dell support and they are going to try change the speakers first although I dont think that is the problem.
