When I connect to roll20 I am able to hear others voices but was not able to get my mic to work. I have confirmed that the mic works and it is some kind of issue with connecting to the site. After deleting my cache and turning off extensions, I played with it a bit more. I have tried in both Firefox and Chrome (updated to the latest version) and have found the following: - No matter what I do, when I sign in I can not initially transmit either voice or video. - When I go to the settings, it is exactly where I left it last time I was on the site (i.e. "Voice only" etc.) - Changing the setting (either from "Voice only" to "Voice and video" or vice versa) will enable the transmission. So technically it works, I just have to go in and change settings every time. I am not sure why this is occurring but would like to be able to change my settings and have it remain set.
