Sound board loop

I have a Mackie Sound Board coming in as my mic/aux in so I can stream to Facebook a Sunday church service. The line in is a fully mixed service including mics and music. I also have a line out to the board so that music and videos can be played in the sanctuary. The problem I am having is that the mic sound in is looping back to the sound board through the line out and sounds terrible in the building. It distorts the sound and ruins the mix that was set on the board. The Facebook stream sounds fine. How do I prevent mic/aux from going back to the sound board before Easter service tomorrow?

You need to split clearly between your monitoring device (rehearsal of incoming signal, going explicitly to something like headphones!) and your lineout, playing video and music into the sanctuary.

If your onboard sound deviates into speaker and headphones, that will be fine for that purpose.
If not, you need a second audio device to play out, or a professional multi-channel one, like a Fireface or something alike.

Again: Your monitoring/rehearsal of the incoming sound must not (more than shall not!) go back thru the lineout back into the church!

I am not monitoring the sound. The line in should not be making noise through the computer. That is the issue. If there is automatic monitoring or a setting in the computer that is making the line in come out of the line out back to the sound board I want to turn it off.

If you mute all playing channels in the windows sound mixer - one by one - when does the loop/echo disappear?

And what exactly is your sound interface in the computer? How is the soundboard connected to that interface?
Some of the onboard devices in laptops have the bad habit to enforce the local playback of a mic/line-in...

Look in the windows audio settings if there is "Stereo mix" of your sound-device listed under the input devices. Then have a click to deactivate...
