HD Radio not working - Known Issue?

[xycrazy]

The radio is working but not the HD radio function. Once selected the radio is like muted. Does anyone know if that's a known issue and whether there's an easy fix for it? 2021 Tahoe High Country

Obviously, I'm the only one?!

could just be a software glitch try disconcerting the battery ground cable for a few minutes and then re attach and see if the issue is resolved.
these trucks have so much software now it's not unlike having to reboot your computer or smartphone.

Didn’t think we had HD Radio…
