[BUG] Unable to capture audio from Stand-alone app on OBS

[JFergen]

Description

I am unable to capture the audio from the standalone app on OBS. I have my OBS setup in a way that I am capturing each individual audio source so that I can change the output volumes in the mixer. If I am capturing my entire desktop audio, I am able to get it, but I would prefer not to do that.

When using the browser version of BOTC, I am able to capture that browser audio as expected.

Steps to reproduce

1. Open OBS
2. Add a Window Capture source and ensure that the Capture Method is Windows 10 (1903 and up). The automatic capture method that it defaults to does not work and only captures the initial image on the app.
3. Check the Capture Audio box
4. Can also add a new source of Application Audio Capture and try capturing audio that way. Both have the same outcome of not working as expected.
5. Make sound in the app and see that no audio is being captured.
