Default Crap sound with headphones plugged in (Nexus 7)

I've been running Omni since the 11/28 nightly. Lately I've been experiencing a distorted, crackling sound with my headphones. This happens during and without audio playback... Wait, I just unplugged the charger and it went away. Why is that?

Found my answer. Appears to be interference.
