audio out of dongle

[elvis1st]

so up until a couple days a go my normal set up in my van was my TP in it's mount with the dongle plugged in with streaming stereo going to the car radio, all while keeping a charger on it,,, something happened... now whenever I plug my charger into the dongle the audio out goes back to the phone speaker and not the headphone jack of the dongle, the dongle works fine unless i plug in the usb to charge...

tried 3 different dongles, 3 different usb cables and 1 car charger, laptop, desktop, wall charger, no matter as soon as there is power to the dongle, audio out switched back to the phone speaker, oh yeah also hard rest and re flashed...running merdihns ROM
