Hello, I have a serious and really annoying problem.
I run Office 365 with Lync on 4 PC's, fully licensed etc..
When I'm logged out from Lync under options I have audio and video and all is fine, devices are recognized.
When I log in or I'm in a meeting, audio / video options are not available anymore (also I cannot share documents)
This happens on 3 of my 4 PC's , the ones with windows 8.1
The one with windows 7 has no problems, all is running fine, I have video / audio in conference etc.
Anybody any ideas?
