Hi there,
I'd like to personally ask that if you have any of these same problems with your Volt, please report them to GM's T.A.C. department. The more people that report the problem, the more likely it will be fixed with a software update. You're welcome to reference this video and mention that you've heard of others with the same problem(s).
Description of problem:
Audio output problem with auxiliary input and bluetooth audio in 2017 Chevy Volt LT. Software version 84089006 Gracenote 23199236.

*** PROBLEM 1 ***
- Audio output does not work -
Both auxiliary input audio and bluetooth audio output do not work at all when the car is started and will not work until the car is turned off. This problem appears to happen randomly, but happens regardless of whether a bluetooth device is paired.
Demonstrations:
When starting car with iOS bluetooth connection:

*** PROBLEM 3 (minor issue) ***
- Audio takes abnormal time to start -
Sometimes, regardless of whether a bluetooth device is connected, the audio system takes an abnormal amount of time to start. Before it starts, a fan somewhere behind the main console can be heard spinning briefly. Audio playback will start after the fan finishes spinning. This is a minor issue to me, but I thought this might be relevant information to pass on. (To me, it sounds like a part of the HMI module has crashed when trying to boot followed by a restart where the fan can be heard spinning... But that's just a guess I'm making about what's happening.)

*** PROBLEM 4 (minor issue) ***
- Chime sounds are staticy/glitchy -
Sometimes the "bluetooth connected" chime sounds staticy/glitchy. This is a minor issue to me, but I thought this might be relevant information to pass on.

A GM T.A.C case has been opened by my dealer regarding this issue (opened on Nov. 29, 2016).
This video was taken after the HMI module was replaced. Replacing the HMI module appears to have made no change to the behaviour and problems.
HMI module was replaced during a service visit to my dealer (Myers, 1200 Baseline Road, Ottawa, Canada) to attempt to resolve the problem. The third party "York Electronics" has been dealing with this issue.
