I'm using TV12 to steam audio and video of some seminars. Some of the remote viewers are reporting poor or non-existent audio. The video doesn't seem to be a problem. I know my settings are correct because most of the viewers are receiving both video and audio. What would cause the audio to fail for some people at the other end? I know one of the participants to have this problem was on a Linux machine and I suspect that was the problem in that specific case. What about people running Macs or older versions of Windows. I'm running Windows 10 at this end.
