Browser source audio not working when controlled by OBS

Hi, I've got a bit of a weird problem...

When i use a browser source and say to "control audio via OBS", the audio does not register at all.
It doesn't output to speakers OR stream.

If I untick "control audio via OBS" it outputs through the Desktop Audio

Weirdly it only happens on one system, which is a virtualised Windows 10 box
The box does have an audio card, and audio can be heard from all other sources.

I've tried
- Disabling / Re-enabling Hardware acceleration
- Allowing obs-browser-page through the firewall (someone suggested this might be an issue)
- Ensuring obs-browser-page is outputting to the correct audio source
- Running OBS as administrator
- A fresh OBS install
- version 30.0.1 and 30.0.0 (both of which work on other systems)
- Portable version with NO other settings and just a browser source
- Changing audio / monitor settings for OBS (changing to a different output and changing back)

No idea how to solve this, Audio works for everything else (including Chrome).
Anything else I could try?

Thanks!
