I have a 2017 Gen 2 Volt for about 3 months now and the bluetooth and ApplePlay was working well. All of a sudden, I can see the bluetooth is connected to my phone, the infotainment system shows which song is playing and the time it's left on the song.. all seems to be working, except I can't hear the music anymore! I can hear Google map's direction but I can't hear any of the music from my phone
I've checked the volume, turn on/off the sound system, reconnected the bluetooth, nothting is working....

HELP!

Dumb suggestion, but perhaps it's the ring/silent switch on the left? I have noticed that some apps respect that switch's setting for their in-app audio. Easy thing to try and move along to the next potential solution if not that.

I've had a simliar issue when I upgraded from an iPhone 6 to a 7. I could see stuff was playing, but couldn't here it. I would switch input to FM and then back to Bluetooth and then I could hear it. I ended up re-pairing my iPhone and that fixed the issue. Hope this helps!

I tried re-pairing, made sure the sound switch is ON on the phone, still not able to hear the music. I hope I don't have to goto the dealer for this...

So... mystery sorta solved... Initially, ApplePlay was somehow shutting off my speaker on the phone. After I unpaired the phone and tried to play music on my phone, it had no sound. I had to reset my phone by turning it off and on again to make sure my phone still worked properly. I noticed it's the Pandora app that was tripping up. It took me awhile to somehow get the latest iOs update and with the latest Pandora updates, it all started to work again.

I have this happen probably once a month, and its drives me nuts. It either says its playing and there is no sound, or it connects/disconnects constantly from CarPlay, and won't play anything. I'm still using an old iPhone 5, but everything is updated. I've narrowed it down to it only happens to me when I jump in the car, immediately plug in my phone, throw it in gear, and head down the road. If I wait 30 seconds or so until I am driving down the road to plug my phone in, it prevents it (at least so far). I'm guessing it has to do with the initialization of the infotainment system/backup camera/plugging the phone it all at once and something gets wonky. At least thats my best guess from the times its happened to me. When it does happen, the only fix I have found is to pull over, shut the car off, turn it back on, and reconnect.

I'm glad it doesn't happen often. I really like the CarPlay interface, but its a real PITA when its not working correctly.

When I was a kid, my dad told me that, when you get into your car, the very first thing you should do is start the engine. Then get comfortable, adjust/check the mirrors, and buckle the seat belt. By starting the car first, it gives the fluids time to circulate and get to were they need to be before the car moves. While this is not as important in an electric car, I still do this out of habit, and it gives all of the computers a little extra time to get up and running before I take it out of park.

I have this problem sometimes with my iPhone 6s.
What I did is switch to radio and back to media.

It always works for me.
I guess the radio system gets confused when the phone is plugged in.

I have had the same problem in my 2017 Volt twice now. The first time it happened I was able to turn off the car, open the door to power down the radio, close the door and power up the car, which fixed it. The second time no sound until it sat overnight. I found a video on YouTube that recommends pressing the black on-star button man with 3 curved lines coming out of his mouth), then when it says "on-star ready" press it again to cancel the on-star call. This should fix the no-audio issue. I won't be able to try it until the next time the audio dies. The video was posted by a chevy salesman who's had calls about this issue.

Interesting fix.....thanks for sharing. I will definitely give it a shot. Since my earlier posts above, we have had it happen with 2 iPhone 6s and an iPhone 7+ as well. I have been getting by with not plugging my phone in until I am 2-3 blocks from the house. That works probably 85% of the time. If I plug it in while in the driveway or within the first block, it almost always does it. It would be nice to be able to fix it without having to pull over and cycle the main power.

On a side note.....my Volt went in for state inspection and 3 open recalls last night. I ended up with a new Impala LT as a loaner. I couldn't care less about it other than the Carplay works so much better than it does in my Volt. The screen looks better and things are running much smoother.....like swiping/loading screens. Even some of the screens visually look different. For instance, within the podcast app, there are virtual buttons visible around the 15sec skip icons. On my Volt, it has the same icons, but no button. It sounds dumb, but I assumed all of that was within the software on the phone. Apparently it is not. When I speak with the dealer today, I'm going to make a comment about it and ask if there are any software updates available for the infotainment system. I know there was the Android Auto update that I never bothered with, but I'm interested to see what they say.

Mine did one worse last weekend. The whole audio locked up, so no sound at all. The radio would not work, phone would not work, on star would not work. I could see the audio was off, but there was no way to reset or turn it on. Tried turning the car off, no luck there.

It reset itself the next day, but it made my 2 hr drive a bit dull. Gm has some real electrical/computer interface issues.
