  • I’m guessing - and this is only from my own, much simpler PCB design experience - that there’s some EMI that’s getting picked up on the ground plane and the headphone jack is not fully or properly insulated. The pitch and intensity of the static will change depending on what the Deck is doing.

    May not be an issue with the ground plane, but that’s just my first guess. Could just be any of the audio lines picking up interference. Would have to do more testing to see if it does it more under load, does it do it if the display is off, or varying the brightness, etc. but it doesn’t bother me enough to dig into it immediately.
