A770 Audio stutter problem

[GTX]

Hi I found a compatibility issue between A770 and audio card.

I tested on Samsung EE-UC10J(usb-c to 3.5mm) and onboard sound(ALC897) and found the same issue.

Stutter occurs regardless of time. It is very sad when stutter occurs during competitive games.

The easiest way to reproduce the error is to open Task Manager after 3 minutes of video or audio playback.

The error is always the same, but sometimes LatencyMon detects the error and sometimes it does not. The attached image is the message when the error is detected.

The linked video did not detect the error in LatencyMon. but, it is a perfect video to explain the error.

I checked similar inquiries, but it is not a ReBAR issue. Driver fix is ​​needed.

The only solution I've found is to always keep task manager open to avoid the stutter.

Thank you.

Hi GTX,

Apologies for the delay in my response. Please share and try the following.

1. What is the graphics driver you are using?

• Confirm you are using the latest WHQL graphics driver available (let us know the exact driver version you are using).
• A clean driver installation using DDU in safe mode is recommended. Follow this link for instructions.
• You could also test using the latest Beta driver. Our Beta drivers go through all Intel quality assurance processes and are safe to use for evaluation.

You may also try updating the drivers from your soundcard and can be found in this link:

ASRock > Z590 Steel Legend

Also, have you tried disabling the ReBar?

Let us know if the issue still persists after trying these steps.

Best regards,

Hi I am glad that the 5989 version driver was released before I tried it.

I used DDU in safe mode to completely uninstall the driver and reinstall it.

I tried various things but did not get satisfactory results.
I tried the following:

1. Tried in BIOS
1) Disable ReBAR (Clever Access Memory) - Same problem.
2) Disable Above 4G Decoding - Same problem.
3) Disable Virtualization, vt-d - Same problem.
4) Disable Ultra Fast Booting - Same problem.
5) Disable Native ASPM - Same problem.

2. Tried in Windows
1) Power Options High Performance - Same problem.
2) Close All Applications in Tray - Same problem.
3) Disable Antivirus Real-time Scan - Same problem.

If this critical issue has not been reported yet, it is likely not an ARC issue. Is the issue not reproducible in the lab?

If so, I will try various things including reinstalling Windows. Thank you.

Hi I am happy to report that I finally solved this issue. The cause is power options.

Set power options to hard disk-turn off hard disk after-1 minute, there is an issue I reported.

If you disable this (it changes to 0 when apply it), the stutter does not occur.

I also had the same issue with my 11th generation GPU, UHD750, so I wonder if it is a universal issue with Intel GPUs.

Actually, I did not have the issue with other manufacturers' GPUs.

I would like to use the hard disk power saving feature to save the planet.

Can you confirm and reproduce the issue in your lab?

And if you use Settings > System > Power & battery - power mode in Windows 11, it cannot manipulate this setting, so it needs to be modified.

Hi GTX,

I will coordinate this to the engineers and kindly give us enough time to work on this and give you an update as soon as possible. Thank you for understanding.

Hi GTX,

To better replicate the issue, please share the following information:

1. Are you using an external speaker or a monitor with built-in speakers to hear the sound?

2. What video ports and cables are being used?

3. Does the issue occur even when using headphones? It seems the problem also occurs when using a jack adapter and the built-in audio card.

4. Have you tried removing the graphics card and using only the integrated graphics?

5. Could you share the exact steps to replicate the issue and describe the exact setup?

Best regards,

hi

1. external speaker

2. displayport 1.4

3. the problem also occurs when using a jack adapter and the built-in audio card

4. I changed Primary Graphics Adapter to Onboard in BIOS and used the integrated graphics.

5. 

After entering Windows, set the power option to hard disk-turn off hard disk after-1 minute.

High performance, standard, and power saving are not important.

You will probably need another disk (for example, D drive) because the drive needs to go sleep.

It doesn't matter whether it's an SSD or an HDD. (I don't use an HDD and I use two SSDs)

After that, wait for 2-3 minutes by watching a video, listening to music, or playing a game until D drive sleeps.

After that, do something that will wake up D drive. The most effective way was to open Task Manager.

The screen freezes for a moment and the sound stutters.

This is one way to force an error. The problem is that this error occurs frequently.

I think it may be a Windows error, but I ask for confirmation because it did not occur with dGPUs from other manufacturers.

Hi GTX,

This is to inform you that we are still investigating this issue. To assist us in further diagnosing the problem, kindly try the following steps:

1. Use different browsers to see if the audio stuttering persists.

2. Could you please let us know if the issue occurs only with online videos and sounds, or does it also happen with media saved on the computer?

3. When did this issue start, and was everything working fine before?

4. Ensure that Windows is up to date.

5. Run the System File Checker (SFC).

1. Click on the Start button, Type CMD.
2. Right click on CMD and select Run as Administrator.
3. Type “sfc /scannow” without quotes and hit Enter.
4. After the scan, restart the computer.
5. Now check for the issue.

6. Run the Deployment Imaging Service and Management Tool (DISM).

1. Click on the Start button, Type CMD.
2. Right click on CMD and select Run as Administrator.
3. In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:

Hi I have run sfc and dism several times over the past month trying to figure out what is causing this issue.

I tried again.

Windows Resource Protection did not find any integrity violations.

No corrupted component store was detected.

The restore operation completed successfully.

It happens with streaming and saved media and even while gaming.

This problem did not occur when using GeForce RTX2070 and RTX4070.

My first SSD is M.2 NVME Type and my second SSD is SATA Type.

I found a way to fix it by changing the Windows Power Options settings so if your lab doesn't reproduce the issue you can close the thread and conclude it is a Windows issue. Thanks.

Hi GTX,

I'm reaching out to you on behalf of my technician. I tried the settings that you mentioned and found that the issue is not reproducible on our end (used graphics driver: 31.0.101.5522 and 32.0.101.6079). 

Considering the situation, it's best to consult Microsoft Support for further checking of the audio stuttering issue.

Okay, I understand. Thanks. Still, I hope the solution I found can be of some help to users who are having the same problem.
