Hi there, I've done some searching around the boards and it seems like this is an occurrence that happens when the amp fails? Has anyone else here had this issue? My M5 is a '14 Comp Pack with B&O and when I start up the car, I get this warning on the center display:

Attention: No Warning Tone

And subsequently, receive no audio whatsoever from the speakers of the car. There are no chimes, no beeping, no radio/navi, and the center tweeter does not lift.

If I try to adjust any audio settings, everything automatically reverts back to default immediately. I used to have this issue every once in a while and the audio would eventually come back after driving the car for a little bit. After the audio came back, I still had to physically press the button to turn the audio back on and all would be back to normal. However, as of late, the audio has never come back.

I did notice, however, that this time, the audio cut out to "No Warning Tones" during a drive. The music was playing (not blasting, volume level at probably 1/4 to 1/3 of full) and then I heard a loud crackle coming from the rear before the audio completely cut out.

Has anyone else experienced similar issues with their M5?
