Lost all audio

[FISHYSMALLS]

2023 AT4 Diesel less than a month old and just lost all audio. Even more strange that the blinkers still work but do not make a blinker noise anymore. ffs
anyone else with anything similar?

I've heard or read where a couple of other guys experienced something similar. Their solution was to open the hood and disconnect the battery, then reconnect it. It appears to have worked. Good luck!

Agree with above. Or your Bose amplifier took a dump. Believe it or not, all the noises for the blinkers, voices, etc. all come through the amp.

The blinker noise is simulated and can be muted depending on a variety of factors including SIRI from a connected phone.

I have a dash cam that I leave on while parked. If i don't move the truck within a few days, or at least start it, it'll drag my battery down. When this happened the first time, I looked it up on line, and discovered that if you pull a fuse on the passenger side dash fuse block while the truck is off, wait a few minutes, then reinstall it, the problem usually resolves. I cannot recall which fuse it is, but on my truck, I used a sharpie marker to mark the top of the fuse in that block for future reference if needed again. I believe that the same fuse would control the sound of the blinkers, and possibly seat belt chime.

My 2021 with the 6.2 did that recently -- lost all audio. I had to stop the truck, turn it off, open the door, close the door, then start it back up and the sound returned. Lots of little glitches like that in this truck. Sometimes the steering wheel controls stop working, sometimes the backup camera stops working (couple times a year), etc. Little things like that.

Same here. My 21' lost audio for the first time yesterday (I have only owned for 2 months). After I turned off/on after opening the door all music was restored.

Same issue here on my 2023 AT4X AEV. I called Sirius radio for a refresh signal and rep talked me through a reset sequence that included turning my truck off, opening the drivers side door, wait for 30 seconds and radio came back on. Also didn't hear the signal light with clicking while turning. Clear indication that you'll have go through a radio reset sequence. It's happened to me twice since my purchase late July. Don't know if GMC is aware of this glitch?
