I had put my experience in a post in February of this year. It involved my 2024 GMC Sierra 3500HD SLT. All the same issues as your truck. Couldn’t hear the radio, turn signals, chimes. After many visits and software updates, it was found that the truck was installed with a bad amplifier. Once that was changed, never had an issue again.
