The audio visual guide has many things listed for permanent audio problem, not much for intermittent one. My bandwith is ok on Download, but has never and will never be ok for the upload.(70 Kb/sec MAX). Still, Skype worked like a charm and Roll20 did work well the 2-3 times we used it some weeks ago. We only broadcast Voice, no camera because of the upload limitations. I will try to tell everybody to clear out their cache the next time (2 weeks), but I seriously doubt it will be any better, because by reloading the page, most of the time the problem vanished. Still last time, suddenly in the middle of a conversation, one person could be heard by everybody but me. Sometimes it was the other way around. I would hear one person, and the others would not hear him. Sorry to say this kind of trouble is the way the web application/server routes the sound communication and has nothing to do with configuration of any kind... In those events, those people were heard and could hear, and all of a sudden it stops for SOME of the people.
