Question / Help How can I make it so the stream can only hear sound from ONE program?

Less just a preference, more a direction to grow to take the cast toward a more professional setup.

I was more chiming in to provide a bit of insight in regards to spending a little more now, to avoid re-buying down the line. Yeah, vb-audio will work fine to a given extent. But eventually you run out of what it can handle, and may just be lost about where to actually go from there to move further. Like standing at the top of a foothill... it'll get you some elevation for-now, but you're going to have to march all the way back down and start up a taller hill all over again when it's not high enough. Dismantle your current way and start over with one with 'longer legs', so to speak.

Yep its just a personal preference. I`m "lucky" to have all that gear at home as a part of my job - so i can use it. Its the same as using a DSLR with a capture card as a webcam - it will give some better quality and nice functions, but its expensive, need more space and the configuration can be tricky. But if you have it sitting next to you - why not :-)
I would buy a mixer every time and use it at home. But this works only because i have only analog audio connections here and with new gear its not always the best option...
