Vanquish - No Sound from Audio - Cause Found
Discussion
For anyone that may encounter this problem in the future...
The tweeters did not rise when the audio system was powered on, and there was no sound at all from any source. It could have been the B&O amplifier since it not only powers the speakers, it also provides the drive for the tweeter motors.
Turns out it was the Sirius module; it was dead. Since all the parts of the infotainment system talk via the MOST fiber optic system, one module going down can take other parts of the system down as well, which makes diagnosing the cause of these types of failures difficult.
Kind of like old fashioned Xmas tree lights were one burned out bulb causes them to all go out...good luck with that.
