If you are hearing what sounds like two audio streams playing at the same time, it means audio from your workstation speakers (e.g. from Avid/Premiere/other media player) is bleeding back into the live Evercast room via the microphone you are using to communicate inside the live room.
There are three primary ways to solve this issue:
1. Use a push-to-talk microphone
This will ensure that participants only hear you when you are speaking.
2. Wear headphones
If you wear headphones during a live session, you should not experience any feedback issues.
3. Manually mute
If you are streaming content and not talking, you can mute yourself using the Mic button on the toolbar. Click it again to turn the mic back on.
Here's how to mute or unmute in the Evercast desktop app:

If you hear feedback while video conferencing, it may be that the sound from someone's speakers is routing back into the room through their microphone. You can discover the offending participant by having everyone mute their microphones individually until the issue stops. Whoever is causing feedback should either use headphones or mute when they aren't talking.
Feedback inside the room can also be caused by two people inside the room who are in the same location and too close to each other. Either ask the participants to move farther from each other, or have one of the participants disable both their mic and audio. That way, you will hear both participants through one mic.
