Almost every time I have music playing on spotify then I get a call and forget to turn off the audio on the head unit, when the call ends and switches back to the music, I will get ear-splitting noise over my speakers, which I am afraid will blow the speakers if it hasn't already.
The noise changes each time, and once it happens, it won't go away until I turn off the car and then restart. Turning off the head unit doesn't work to clear the issue.
I've been able to circumvent the issue by pushing the power button once the call starts, and leaving it off until after the call disconnects. Then upon pressing power the music resumes without any issues.
Is there anything I can do to make this go away? Everything else works fantastic, calls, music, this thing is amazing.
