I ran into an odd problem with echoing happening with Roll20's audio chat function. The echo would occur when multiple players had logged into the system; it was not a problem for one-on-one chat, nor have I had this happen through Skype (though Skype has other problems with connectivity). Has anyone else encountered this echoing issue and if so, what would you suggest as methods of eliminating the echo so roll20 can be used in place of Skype? I am currently using Chrome for roll20 and outside of one player using Firefox, I believe everyone else uses Chrome as well. We're using WebRTC as we could not get Flash to provide any sound.
