Expected Behavior

When changing a scene, the source transition should be completed no matter if the new scene contains the source or not.

Current Behavior

When triggering a Source's visibility transition by toggling the source's visibility and switching to a scene where the source doesn't exist, the transition fails to completely turn off the source. The output of it will be turned off, but monitoring capabilities of the audio source aren't will prevail with the status before toggling the source visibility

Please find a video explanation attached;

.

Steps to Reproduce

1. Add an audio source.
2. Give the audio source a show/hide transition, in this case Fade in 2000ms and Fade out 3000ms.
3. Hide the source and immediately show it.
4. Switch to a scene missing the audio source right after toggling visibility ON.
5. Hear the monitoring of the source while the output can't.

Can confirm, also an issue on Windows 11.

I can also confirm on Linux (Fedora 34). At the step 3, it's not necessary to immediately show it. The issue happens when transit to another scene while the show-transition is running.

Also should mention, there seems to also be issues when switching to another scene with the same audio source, it does not have to be missing.

I have a Spotify scene which just has an audio capture of the spotify application (Spotify outputs to a specific virtual audio cable). I have seen this issue switching between scenes where the source is still embedded in the scene (the spotify scene is in the destination scene) but I still see the same issue (while the source is hidden - spotify continues playing through the monitor (incorrectly) but does not output to the stream)

Notice the same issue in the Audio Mixer in obs 28
