No audio - intermittent issue

[camjr]

Hello all.  2021 GMC Sierra 1500 Elevation X31 Duramax.  Infotainment package.  The truck has been trouble and issue free since I purchased in June.  Yesterday as I got in and started it up, there was no audio from the truck, despite the head unit controls on the screen looking normal.  Radio was silent, internet music was silent, and phone calls were silent.  Complete silence.  I tried adjusting volume, muting, turning on and off, etc., nothing.  I pulled over, turned off the truck, started it back up, and the same problem continued.  When I got to where I was going and turned it off for about 20 minutes while I had an appointment, all audio worked as normal when I started it back up.  Anyone had anything like this happen to them? 

 

***** Nevermind - I found the other thread.  Can't find out to delete this post.  Cheers.
