I have tried Wirecast and Gocoder to send a stream using WebRTC, I am using the demo play.html to view the video in Chrome… The video is playing great, about 1/2 second delay but the icon to unmute the audio is greyed out. Any suggestions? ---

Were you able to resolve this greyed out icon? You must have the most recent version of Engine- do you have 4.7.7? This is the version where WebRTC is out of preview and has more functionality. If you are still having an issue, will you kindly submit a support ticket? [https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket)
