This is actually a problem with Chrome's most recent version (v50) and
WebRTC. Chrome's newest beta version fixes this issue. You can either
switch to the Chrome beta track or use Firefox for the mean time. The
official release of v51 probably won't happen for another 2-3 weeks,
sadly. There is another thread that we are following, and will
post in if we figure anything else out. If you have any further
questions/comments please post there, I'm going to close this thread to
try to consolidate everything about this issue into the one thread. <a href="https://app.roll20.net/forum/post/3295391/group-can-hear-me-i-cannot-hear-anyone-else" rel="nofollow">https://app.roll20.net/forum/post/3295391/group-can-hear-me-i-cannot-hear-anyone-else</a>
