Question / Help Looking for suggestions for a low-latency multistream setup, with audio mixing support...

Hey everyone. So I have this goal which I have a few ideas how to tackle, but looking for suggestions and improvements.

Basically my goal is...

Streaming from OBS, with a bunch of other streams (from mixer.com or twitch) as the sources. Being able to switch between these and hear only their audio, or at least have individual control of their volumes.
These input streams need to be low latency. So ideally I'd be using a browser source pulling from mixer.com or twitch with low latency mode enabled for each streamer.
However the limitations of the browser source means all audio goes to the default audio output on windows. So we cant mute the not visible streams without telling it to actually disable them when not being viewed, which means lag, and in the case of twitch, an ad, every time we switch views.

Currently our approach has been for all of the source streamers to just not enable any audio, and for only one person to keep theirs enabled, with no mic, and the final stream guy will have discord open with all of us in there.

Its a pain :P I'd love to be able to use media source with an rtmp server we host, everyone streaming to that. Those, I believe would each get their own audio controls, but... rtmp is SLOOOW. afaik there's no way to use a WebRTC source, but I did see there's a fork of OBS to stream to webRTC, so if I could get a source plugin to read that...

Anyways. Anyone have any ideas?

I haven't used this myself, but to solve your audio problem you might want to look into this chrome extension, and use Virtual Audio Cable to create as many virtual lines that you need to give each streaming source its own virtual device. Then it would be a simple matter of just including the appropriate cable for each stream capture.

That's only to fix the audio in your current workaround though. Not sure how to do a more elegant way for full stream switching.
