Echo just started a few weeks ago

We are using OBS to stream our worship services. We have the sound mix from our PA system coming into a PreSonus Audio Interface. We also sometimes run videos as part of our worship, so we use the headphones jack on our computer to send that audio signal out to the PA system. That was all working well until about 4 weeks ago. All of a sudden we have a really bad echo that makes our audio horrible in our stream. Anyone have any ideas what might be causing this? To the best of my knowledge we did not change anything.
 
As always:

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Aside of that: Sound from your congregation/hall comes thru the presonus into your machine. Playback sometimes goes out thru the headphone of the onboard soundcard instead, right?

Where could the echo be heard? On the inhouse p.a. or just and only on the stream?
 
That is correct. And we can hear the echo both in the sanctuary and the stream. I have discovered that if on the input signal from the computer back into the PA system we remove that signal from the main mix, the echo goes away. It also goes away if I simply mute the input signal. That works unless I have something I want to run from the computer such as a video.
So I am really wondering if any one else has seen this, and especially if anyone else saw it after a recent OBS update?
 
It merely depends on which sound device windows takes as its "standard" output device.

Hence you have two devices (onboard sound card plus the presonus) you should clearly divide those:

- Take one devices physical output as windows standard (you can set in the windows audio settings) and use this as normal playing output of all windows applications (hence your video players, too). This device you physically cable into the mixer/soundboard.

- The other device you just use as the monitoring device (set it explicit within the OBS settings as monitoring device just for OBS) and use this with earphones cabled in.

So you can monitor and proof by earphones the sound coming from the sanctuary going into the stream while playback of video plays out thru the other (standard) device into your sanctuary mixer and can be heard there. The main principle hereby is to have two distinct audio paths via two sound devices, clearly separated from each other. So no monitoring from the sanctuary goes back into the sanctuary (which built the loop).
