We've used your MoveTransition Filters for a long time to simplify the management of scenes and sources within OBS, so that our volunteers don't get lost-in (or forget) important details during our broadcasts. - And your plugins work great. We use your widgets extensively to fade-in/fade-out subtitles, show or hide visual overlays, turn on (or off) the Virtual camera, start/stop recording, etc.
That said, we'd like to do something similar with the audio feed: We do all of the audio mixing externally, then feed it into our windows machine via USB, which we feed into OBS as an audio Input. I'm trying to use your Audio Move filter to (1) enable the OBS Audio Mixer source we're using, then (2) set the audio level to a reasonable value. Can't figure out how to do that. Any guidance or help would be appreciated.
