I made an account just to talk about this... I've been getting some strange audio errors and now crashes from this plugin.
My goal has been to separate 3 audio devices and 2 stream visuals, with 1 recording stream having 2 audio devices and 1 visual, and the other stream having all 3 audio devices and the other visual.
This was achieved easily on Streamlabs OBS, but has proven difficult on OBS Studio. I made use of this plugin to try to achieve this.
Originally, I tried using this plugin to record while I stream, but the audio in the recording I would describe as ALL or NOTHING. When I made use of the "different audio" option, if I select anything except for None, it ALWAYS plays all 3 audio devices, no matter my settings.
I then think about reversing things and using the plugin to stream as opposed to record, because I can use built-in audio functions to have the recording have only 2 audio devices. My only problem now is that whenever I end the recording or stream in the Source Record filter, my OBS crashes.
