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.
Works perfectly on LTSC 2021 21H2. If you're running an older LTSC version, try 1.0.0-alpha.2. It works for some applications and is better than nothing. The only thing I dislike is if you mute OBS in Windows mixer, then this plugin doesn't capture any sound.
This plugin is actually a godsend compared to having to use voicemeeter. Yes, my OBS does crash maybe once a week but its a quick restart and it never happens when I'm live or recording. Totally worth it as it's only a beta.
The only gripe I have is that the audio sources show up in the source window as sources. If there could be a way to make this work cross scene without having to use duplicates or make it work inside the audio mixer window the plugin would be essentially perfect and something I would have expected to be in base OBS.
I recommend this plugin to absolutely everyone. Voicemeeter is just waaay too intrusive especially when I'm not using OBS and this plugin completely fixes that for me.
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.
