Radio issue goes quiet

I have a 2023 GMC Sierra Denali and the radio was fine when i purchased it, but now it goes quiet and then returns to normal. I have done the reset. Also have taken it to the dealership, but they said it was the Apply Play app when connected to my phone. I researched Apple play app and that was no help either. But I noticed the other day the issue was happening, and my phone was not with me. Has anyone got a resolution on this issue?
I had the same issue. The dealer replace an amplifier and it has worked ever since. I hope this helps
