HP Z34c G3 WQHD Curved Display
Microsoft Windows 11

I'm using the HP Z34c G3 since a long time. But, I always had the problem there was no audio output / no mic input. The monitor was simply connected via USB-C. It was also shown correctly as input and output device in Windows (no driver issues from my point of view). Workaround was the disable "Enable Audio" from Input > Audio and re-enable it (after every Windows boot...).

Since I already gave up on this - finally, there is a solution: HP released a new firmware on the 29.07.2024 that fixed this issue on my end - version 1.2.20.0 Rev.A:
