ARC A770 & Re-Bar Audio Issues

[n64robert]

Since switching to the A770 from Nvidia, I've experienced audio issues. Mainly stutters and hitching, usually when loading new web pages, especially Youtube.

I reinstalled Windows 11, and the issue persists. The strangest part is that it doesn't matter whether I have the audio go through the Displayport to my monitor, the 3.5mm headphone jack on the motherboard or through my Steelseries GameDAC. It happens to all of them.

That is until I turn Re-BAR OFF. Since doing that, the issue has gone completely. The motherboard is on the latest bios, and all drivers are up to date.  

I also tried putting my Nvidia card back in and all the issues went away immediately.

Full system Specs:

Intel 12700K

Z690 TUF GAMING Wifi D4 - Bios 2204

64GB RAM

A770 16GB

Latest Drivers and Bios as of 18/01/2023.

I hope this can be resolved because it's very frustrating, and so much performance is lost when Re-Bar is off isn't acceptable.

Hi all, 

I found a trick , you can enabled rebar in the bios and connect your computer in bluetooth with an Dac/amp, the audio works fine without issues 😉
