Expected Behavior

I used alerts from Streamlabs and Blerp.
They should show a gif or video and play a sound if a correspondent events fires.

Current Behavior

The alerts work as expected for a seemingly unpredictable time.

I think it takes about 10 to 20 minutes until the alerts stop working.
The sounds won't work anymore. Animations sometimes still work.

Steps to Reproduce

1. Add a browser source with Streamlabs or Blerp alerts (It probably works with anything that uses sound and/or video)
2. Make sure "Control audio by OBS" is checked in the browser source's properties
3. Activate "Monitor and Output" for the browser source's audio
4. Start a stream (not sure if necessary)
5. Wait 10 to 20 minutes
6. Fire an event that should trigger an alert

Anything else we should know?

Does OBS being minimized or hidden by another window have any influence on this happening?
If it only happens with OBS minimized/hidden, this is likely related to #7588

I'm sure it was never minimized.
Sometimes it was covered by another window (OBS and the other window both maximized), but I don't think that would be considered "hidden"?

EDIT:
One of the steps to reproduce #7588 is "open OBS again wait 10 seconds the problem disappears".
I can confirm that this not working in my case.
