Hi @rwenner007 ,
Does this occur when using the aux in connection as well as the BT connection?
If only on BT it might be the aux in jack.
Not sure whether the BT audio comes through the jack contacts and is disconnected when a cord is inserted or whether the jack uses a contact to signal the audio controller to switch inputs when a cord is inserted but still maybe worth a check anyway
