Ok. If I get up the nerve, I'll try Voicemeeter to see if I can do this. I don't do many vids, I mostly am doing some KSP flight vids just to amuse myself and try to produce a video I can watch comfortably. That's about as far as it goes on me making videos but it's nice to know how to do it. I'm more worried about what the program is doing when I'm not making a vid. I'm primarily a speaker guy, just never got into headphones, can't wear them for any length of time without major discomfort. So only time I use a headphone (or a mic) is when I'm trying to make a video. I just plug in the usb headphones/mic and of course this instantly changes everything in the Windows mixer switching default audio and playback devices. I then open the game and OBS and try to record a decent vid of me playing the game. When I'm done with the recording, I close out OBS, unplug the USB headphones/mic and then watch the vid through my player (potplayer) through my normal speakers. If the game/mic volume balance turns out decent, I then upload it to youtube. It's a bit tricky for me on the game/mic balance as I said before. In KSP (Kerbal Space Program) the game volume changes during the play as you are using louder or softer sounding rockets during a flight. The tricky part is knowing how the volume of what I am hearing through my headphone is balancing with the game volume that is actually being recorded because what I am hearing through the headphone is ALWAYS going to be louder than how the recording comes out. I always have to remember to adjust for this as I'm playing. Say when I'm on the first stage (loud) rockets, it's so loud in the headphones (but listening to this same volume through speakers would be perfect), I catch myself shouting into the mic. So I alt-tab out during this liftoff and turn the game volume in the Windows mixer down so I can hear myself talk. Then later in the game when the louder rockets have been used and the game is much quieter, then the volume in the headphones are not loud enough so I alt-tab back out and turn up the volume in the mixer again. I have to do this a few times during play to end up with something kind of balanced at the end.
