I have a standard deployment on 1 FE and 1 edge server. Nobody is connecting through the edge server - the presenter and all participants are all on the same domain and on the same lan.
The intention is to have one presenter who needs a microphone and a few dozen participants that won't speak and don't have microphones. I found that when an online meeting is set up, I can invite people with webcams and they join without any problems. Those without webcams get an error when joining: Audio device is not configured.
Our OCS 2007r2 didn't have this issue, so I'm pretty sure that I just have something misconfigured. Any ideas what that could be?
