I'm mostly lost at the virtual output part, how do I merge several inputs into one output, especially StreamDeck which only plays to one output, it is not a device that something can listen to.
1. I should hear the game (movie,...) I'm playing on the speakers
2. Any conversation from Discord + StreamDeck effects (so I have audio confirmation they're playing to discord) to come outside my desktop Jabra
3. My discord teammates should hear only my voice and StreamDeck effects
4. Twitch audience (via OBS) should have it all mixed (but only once ofc). OBS can map each audio source on its own, but StreamDeck is not device to listen to, hence the need for SD-Out. I guess that is where VAC would go, but maybe it's part of VM/CCNT too?
