How to streaming the final ue4 audio to other app?

hi! I have the following problem:
I’m using a Oculus Quest (android standalone VR headset) and i’m using a dev app to videostream what’s happening on the device, but this app don’t stream audio.
I can’t use a chromecast because needs internet (oculus requirement), and can’t count of having internet, only local network.

So, how can i stream audio out of my app in a standard format that any player can read it in a local network? Any clues?

I use Voicemeeter Potato, it supports VBAN so we can stream audio over network to and from IPs etc

checking… thanks!

Oh, but this is only for windows, right? I need help for ue4 in android vr device
