ARC A770 & Re-Bar Audio Issues

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 Robert,

 

Thanks for your reply. 

Reviewing Device Manager there are no error messages and everything seems to be installed correctly.

I only get messages preparing new devices when I plug something new in which I would expect to happen.

Cards been reseating when I switched graphics cards back so yeah that's been done. 

Txt file attached as requested!

 

Thanks

Hello n64robert


We are still investigating this issue. We have some suggestions and we also need some extra information from you:


1.-Please share with us a short video showing this issue as it will be useful to try to replicate it.

2.-Does the same issue happen if you disconnect the SteelSeries GameDAC?

3.-Please use the Display Driver Uninstaller(DDU) to completely remove the previous driver from your third-party GPU.

4.-Please try an older driver like driver version 30.0.101.3490 just to discard any regression, if the issue persists you can roll back to the latest driver and you can also test the latest BETA driver 30.0.101.4090 that recently came out.

5.-Please run the Intel® System Support Utility and attach the log file to get more information about your system.


Best Regards,

1. Getting a video of the issues isn't really easy for me but with more time I may be able to get one done.

2. Same issue happens if I disconnect the GameDAC

3. Third party GPU hasn't ever been plugged in on this fresh installation of windows and thus there are no drivers to uninstall.

4. Issue has been present on the last 3 retail driver versions and persists in the latest BETA version.

5. Attached.

As before disabling Re-BAR fixes the issue completely.

The issue seems to occur whenever there is a CPU spike when loading a heavy webpage or a Adobe program etc. However tryng to replicate it though a single thread CPU stress test doesn't prompt it. 

I'll keep testing.

Thanks

Hi Hugo,

 

I've done my best to catch it on video. You couldn't really hear the first couple of tries, but I got a capture where you can hear it. 

 

The easiest way I found to provoke it was to have youtube open and play something and then open a heavy program like Adobe Photoshop; this is precisely what I did in the video.

 

The skips match perfectly with the dropped frames on the stats for nerds as well, so you should be able to match it up.

 

To be clear, this issue happens with other things, not just Youtube, but it was most reliable in reproducing it.

If there is anything else I can do to help please let me know

 

Many Thanks
