Issue reported - Current Behavior

This crash is found at user's side with PRISM exiting. I do not find the reproduce steps.
the audio_thread created by ndi (6.1.1) is not closed during exiting.

1. obs_shutdown has been called

2. However, the audio_output in libobs (0X1FE37C1D540) created by 3rd plugin is not exited

3. we can find this audio_output is set for this output (0X1FE37CF56A0)

4. this output (0X1FE37CF56A0) is created by ndi plugin

Expected Behavior

during exiting, the created audio_output should be closed

Steps To Reproduce

I have not reproduced it.
This crash is happened at the user's with PRISM Live Studio

Environment

- OS:  Windows 11(x64)
- OBS:  PRISM 5.0.0.635
- DistroAV: 6.1.1

This issue was modified in the past
https://github.com/DistroAV/DistroAV/pull/996

I find `audio_output_close` is only called in `preview_output_stop`. 
`preview_output_stop` is called from `OBS_FRONTEND_EVENT_EXIT》preview_output_deinit`

That front event is also sent from PRISM as obs's code.
