I have a strange problem with audio and video transmission during a conference.
When I start the conference, all participants can see and hear me, but I neither see nor hear anyone myself.
When I select my camera, however, I see myself in the small selection window. As soon as I switch back to conference mode, all participants are black and I cannot hear anyone.
What can be the reason?
A Surface with Windows 10 is used, all authorizations are granted and the virus protection / firewall is switched off. Everything runs smoothly on the iPad and Android tablet.
