Re: Integrated Laptop WebCam not working

What hardware should this be? Make sure there's no BIOS/UEFI or hardware switch to dis-/enable the mic. Which exact laptop model? Output of

sudo journalctl -k

?

You enter the BIOS and look around the settings.
Also https://storage-asset.msi.com/global/pi … -s-nb2.jpg - Fn+F6 looks like a webcam, the manual will certainly explain that as well.

There's currently no trace of any v4l2 device in the journal, loading the loopback device won't help at all.
