21 Tahoe intermittent Sound

[gma63]

Infotainment system intermittently loses sound. Screen still works just no sound. No bluetooth, no signal light sound.
Took to the dealership, said it needed a software update. Installed. Worked for a few months, now worse than ever. It cuts out all the time. Any one have any suggestions? Will take back to the dealership but want to be informed.

That’s strange. The only issue I have with sound on my ‘21 is the turn signals where the electronic clicking noise will disappear for a bit then return.

Same, but also coinsides with the radio cutting out. Has lasted up to an hour of no sound, but usually just cuts out continuously. Super annoying!
