MSI Vector 16 HX AI A2XW, audiodg.exe heap corruption crash, Intel? Nahimic? Intelligo?

[Vriks_of160702ef]

I have a Vector 17 HX AI A2XW, and I had the same issue. Audiodg.exe (ntdll.dll) was crashing periodically. I also tried installing different driver versions, uninstalling Nahimic, and so on. In the end, I reverted everything back — all drivers are installed from my laptop’s page on the MSI website.
Then I simply went into Device Manager, Audio Processing Objects (APO), and disabled the device “Intelligo Audio Effects Component.” After rebooting, the problem was gone. While I was there, I also disabled “Voice Clarity,” just to reduce the number of unnecessary layers in the audio stack.

As a bonus, I also had another issue with sound. In Bluetooth headphones, the audio would periodically start lagging and freezing about once per second, endlessly. A temporary fix was, for example, switching the output device to something else and then back to Bluetooth, but the issue would return.
What fixed it was forcing the codec to switch from AAC to SBC. You need to add two lines to the registry — you can easily find which ones online — and then reboot. After that, there were no more issues with Bluetooth headphones.

I also had a problem where, when using wired headphones, there would sometimes be background noise or a humming sound. To fix this, I bought a USB Type-C to 3.5 mm jack adapter and now plug my wired headphones into the USB Type-C port. Adapters can also introduce noise or hum, but if you get a good-quality one, it will be completely silent with no loss in sound quality.

After all that, I have no more audio issues. Hope my experience helps someone.

Thanks for your feedback, I will definitely try disabling the intelligo driver, but after you did that, were you able to use the automatic (ai) noise cancelling feature from MSI center? It is a feature that works really well and I use it all the time..

Hi. I don’t use this feature, so I haven’t checked whether it works or not. The point is, I didn’t delete anything — I just disabled the Intelligo device in Device Manager and rebooted.
If something stops working, you can simply enable it again and everything will be back to normal. So there’s really no risk in trying it. If you want to be extra safe, you can create a restore point, but you likely won’t need it.
The important thing is to reboot after disabling or enabling the device — otherwise, it won’t have any effect.
If the errors stop after disabling it, at least you’ll have localized the problem. From there, you can either try different driver versions to find a stable one, or just switch to another noise suppression solution. There are plenty of them now: Nvidia Broadcast, SteelSeries Sonar, Krisp, Equalizer APO + RNNoise, and so on.
These are all proven tools that handle the job really well. That’s how I’d approach it.

Hello, I tried it and unfortunately it didn't change the behavior of the sound (still got some sound glitches).. So my issue is different than yours (I also wasn't getting any of your "bonus" described errors).

Hello, I tried it and unfortunately it didn't change the behavior of the sound (still got some sound glitches).. So my issue is different than yours (I also wasn't getting any of your "bonus" described errors).

Try opening Task Manager, go to the “Services” tab, and search for an IntelliGo service — for example, something like “IntelliGo Audio Service” or similar. If you find it, try temporarily stopping it in services.msc and set its startup type to Disabled. Then also disable the device in Device Manager, reboot, and check the audio.
In my case, this service wasn’t there, so there was nothing to disable. But I’ve seen that some people do have it and disable it successfully.

It’s just that too many things point to IntelliGo being the cause of the audio driver crashes. In my case, the problem was fixed by disabling it. In this thread, someone mentioned that installing a different driver version solved it. I’ve also seen other reports where people fixed this issue by disabling IntelliGo.
So the fact that it didn’t help in your case, I would attribute not to it being ineffective, but to IntelliGo still running even after you disabled the device. Either some utility is still using its driver — for example, through a running service — or something else is keeping it active.
If you want to really dig into it, I would create a restore point or a full system backup first. Then I would remove everything related to IntelliGo completely

• 1. Disable the IntelliGo service
  Press Win + R, type services.msc and hit Enter
  Find IntelliGo Audio Service
  Open it, set startup type to Disabled
  Click Stop and then OK
• 
  
• 2. Disable it in Device Manager (APO)
  Right-click Start → Device Manager
  Go to Audio Processing Objects (APO)
  Find anything named IntelliGo Audio Processing Object
  Right-click and choose Disable device (don’t uninstall it)
• 
  
• 3. Turn off audio enhancements
  Go to Settings → System → Sound
  Open your output device (speakers/headphones)
  Set Audio enhancements to Off
  If there’s an Advanced tab, disable any extra audio features there
• 
  
• 4. Remove the software and block reinstall
  Uninstall IntelliGo Neptune
  Press Win + R, type sysdm.cpl
  Go to Hardware → Device Installation Settings
  Select No so Windows won’t reinstall drivers automatically

5. I would also disable anything related to AI audio in MSI Center ance clean the registry with CCleaner, fore example.
After that, reboot, and try again. If it still doesn’t help, I could roll everything back in 5 minutes and at least I’ll know that IntelliGo definitely isn’t the cause, but I think it should help.

updating Realtek audio to last drivers from MSI solved issue on my Vector 18 HX AI A2XW

EDIT: forgot to mention that I have also updated "IntelliGo Audio Processing Object" and "IntelliGo Audio Software Component" to newest versions.

updating Realtek audio to last drivers from MSI solved issue on my Vector 18 HX AI A2XW

which version?

 

[LostSouls]

It is solved (in another thread: https://forum-en.msi.com/index.php?threads/stuttering-sound.418409/post-2378694).

Intelligo audio object driver should be updated (you can get the driver from Microsoft update catalog). The MSI driver is outdated and apparently caused all the problems (in most users).

Can anyone confirm? What is your "set" of drivers for all Realtek, nahimic and other stuff related to sound @LostSouls

Check the thread link I provided (Stuttering Sound MSI Forum Thread). Read it from start to end. Everything is explained there in great detail from many users. To sum up, it seems like from a certain version of intelligo audio object driver and later, the bug was fixed. It's a shame it isn't available at the official MSI website, and that we have to go out of our way and get it from Microsoft Update Catalog. Every other sound driver I have, is from the MSI manufacturer website, latest versions.

You need to research how you extract the driver cab file (from Microsoft Update Catalog) and properly install it through device manager, in case you don't know.. It's not difficult at all.

After you read, there is no harm in trying out. Solution was found by user @Anton Chigurh.

I told you. My other audio drivers are the ones that are available at the official MSI website. I only changed intelligo driver to the very latest from Microsoft update catalog.
