This has been plaguing me since I accepted delivery. I've tried all variances, bluetooth only, USB stick with music, spotify, etc. The 2 thumb reset always fixes it. BUT, going on 2 weeks now (still haven't had a software update since I got the car, service appt. in a couple of weeks), if you leave Immersive sound OFF, this doesn't happen. I tried the AUTO setting as well, but it glitched right away. I believe immersive sound is really only meant for watching Video. So fingers crossed, leaving immersive sound off is working for me, as this would happen almost immediately on the next trip in the car after a reset.
