Hey guys, I have a very weird problem with my X570-E Gaming motherboard and Elgato Cam Link.
I have used the Cam Link before with my X470 Crosshair VII Hero but upgraded to the X570-E Gaming as I needed/wanted access to PCIe 4.0 (Crosshair VIII Hero here is $100 more expensive than in the US and that is without VAT whereas the X570-E Gaming has roughly the same pricing as in the US...)
I am using a Canon EOS RP through an Elgato Cam Link.
Today I have a Teams meeting and notice that my camera freezes immediately when I join a call or if I go to settings and check the preview. It's always a frozen image from RIGHT when I opened the setting or activated the camera in the call.
Aside from the Cam Link I have a Microsoft LifeCam Studio connected to my PC. I made sure they are not on the same USB Root Hub.
When the Cam Link is attached to the X570 Chipset USB Root Hub: All cameras work perfectly fine outside of Microsoft Teams. They work fine together in a scene in OBS, they work fine in Microsofts own Camera app, they work perfectly fine in Microsofts own Skype for Business suite, they work in Discord.
When I open Teams the Cam Link freezes, my webcam continues to work though.
When the Cam Link is attached to the CPU USB Root Hub: all cameras work fine outside of Teams, same behaviour in Teams as when it's connected through the chipset. However, if I start a stream or put my CPU otherwise under load the camera freezes instantly or within about a minute in any app.
What I have tried so far:
- used USBDeview to remove all disconnected devices, then removed all connected devices too
-uninstalled and reinstalled Teams
-uninstalled and reinstalled Teams with deleting all Teams folders within AppData
-checked the integrity of the windows image and installation using DISM and SFC
-uninstalled and reinstalled every capture device (Cam Link, LifeCam Studio, Elgato 4K60 Pro II)
-uninstalled and reinstalled capture software (Elgato 4K Capture Utility)
-uninstalled the OBS Virtual Camera plugin
-ran Windows update, installed optional updates for Webcam (LifeCam Studio is then in the device manager under Imaging Devices and not Cameras anymore)
-removed all NDI plugins from OBS and Windows
-changed USB BIOS settings, reset BIOS and used optimised defaults, tried BIOS 2816 and 2802.
No change in behaviour
I also reinstalled OBS again and tried OBS Virtual Camera in Teams (Cam Link on Chipset port) and then I can get my Cam Link picture into Teams without freezing.
This is all very weird and I am wondering whether or not I have a defective mainboard or whether this is a known issue. All other USB devices, as far as I can tell, continue to work fine while on the CPU USB Root Hub and with the CPU under load.
