So my wife’s ST seems to be having audio problems while on a phone call. When I talk to her I get a feedback of my own voice that comes and goes throughout the conversation. Also just today we kept hearing a random squeaking noise that would come in on the call that almost sounded like a brake squeal, but it seemed to originate from her stereo. None of this happens when she is driving my car (2014 BMW). Has anyone else experienced this or something similar?
