Hearing yourself through the stream in the Evercast room? This issue is caused when EBS is configured with an audio source that also has participant audio traveling through it. Here's how to solve it.
You should either video conference on a separate computer or connect a different audio output specifically for Evercast participant audio (e.g. USB speakers).
If you have USB speakers already, change the speaker output of your Evercast session by clicking the 'More' icon in the toolbar at the bottom of your Evercast room. Click 'Device Selection,' then 'Audio Output,' and select your alternative speaker output from the dropdown menu.
