I have this same problem after the latest windows 10 update. Did backing up the drivers to an earlier version resolve this issue? Any help is appreciated. I can share my webcam and people can see me but I am unable to see others shared webcams video.

Sorry, @psalingue --
Did you go through the Dell website already to test the newest Vs. previous driver versions?
Can you confirm the GoToMeeting version as well?
