Managed to replace Voicemeeter with this plugin and it's pretty amazing. I only have issues with it not having game detection to associate it with a source but also because my OBS now freezes when I'm closing it and has to be force closed.
Works great on Window 10 21H1, I've had no problems with OBS itself picking up Audio from my applications. There are some application-specific quirks, especially related to audio sources in webbrowsers, but nothing I consider a dealbreaker.
On the whole, I think this plugin provides a feature that is Instrumental to streaming via OBS Studio.
As it is in early stages, there's quite a few creepy crawly bugs here and there but overall does its job.
Can't wait for what it'll be like a few releases down the line. I can't wait to use it more often then.
This plugin is a fucking game changer. Last build (24 hours ago) stopped working after 2 minutes, this one works perfectly. I am able to capture only my spotify while running youtube in the background, and anything else doesn't get captured. Highly recommend to any and all streamers of any sizes.
