Bose Audio and no sound - possible cause

[gianteli]

For nearly two years now I’ve had random instances where on start, my phone would connect to carplay but no audio source (carplay spotify, apple music, radio) would result in sound. I’ve had every software upgrade and most components (bar the control module) replaced. On the most recent instance of this, where the lack of audio persisted after several restarts of the vehicle and soft-resets of the PCM, I got a phone call and was able to have a normal conversation. This gave me pause…it clearly wasn’t an amp or cabling issue so it might be a processing problem. So I went into the bose settings and selected “stereo” in lieu of “surround” and turned off the variable volume options. Viola, music. Since then I haven’t had the issue again, so this wasn’t precisely a controlled test.

I’m also sending this over to my service department but thought it might be helpful for this group.
