Realtek Camera Issues

[ITA94]

Seem to be experiencing an issue with the laptops we're deploying where the onboard webcam (All showing in device manager as "HP 5MP Camera" with the Realtek driver version 10.0.22000.20340) during the Teams meeting is constantly shutting off (white light comes on initially then turns off then their image is frozen until the end of the meeting. Turning off the camera button and enabling again doesn't fix it).

With my testing on another laptop with the same issue, noticing when I use the Camera app to test, when I first launch when the PC comes up, it works, for a bit then freezes and then I can't bring the image back up until I reset the "Camera" app.

Troubleshooting done:
- Uninstalled HP 5MP camera and scanned for hardware changes. Same issue. Even repeated steps and rebooted

- RAN HPIA and updated BIOS and the camera driver, same issue

- These PCs are caught up on Windows updates (They're on W11, 23H2 though. Not sure if a fix for this has been addressed in 24H2 but we won't be able to get that anyway until we actually deploy out, so 23H2 is all we have right now)

- Sent to the HP depot for a repair. They didn't change the hardware, pretty much just reimaged it and ran updates and "Extensive testing". When I got the laptop back from their depot the issue immediately happened again when I tested.

- Added the REGDWORD entry (EnableFrameServerMode, value set to 0) for 64bit systems in location - HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform and in the other location I can't remember atm.

Based on my research aka Google, it seems that what's causing the is between the Windows Camera Frame Server and Windows Camera Frame Server Monitor services. Verified this by running the Cameras app test and going to the windows event viewer. Everytime in the Camera app when it freezes, seeing:

Seems anyone who's researching this issue has reached this point in finding what the cuplrit(s) may or may not be but it stops there. On my test PC, I disabled the "Windows Camera Frame Server Monitor " service and rebooted. It does seem like it helps a bit, freezing isn't happening as much but still occurring, seems the webcam is coming up quicker too. Disabled the Windows Camera Frame Server service as well but then couldn't use the camera at all so left that alone.


Is there anything else I can try out? Seems there's basically no support or workaround for this that's working
