The good news is that I am learning how to get my Windows Mixed Reality / VR equipment set up and ready to go faster. There is less troubleshooting, thanks no doubt to the formal release from beta of WMR for Steam VR. But we're still trying to nail down how to record. My multi-patch cable, hardware-centric approach failed. There was audio bleedover from one of the several cables that I had connected, cross-connected, and piggy-backed. Later in the week, I think I discovered that the speaker output connector to my secondary streaming PC was halfway out and may have been the cause of the static we were hearing.
Regardless, I had a blast playing paintball in VR with my good friend GreyLock from The Gamers Show (https://www.youtube.com/channel/UCWw_uWjWDGBNkYHT4i36G9Q). I think I am getting a handle on the Sniper rifle, although it points out some of the design flaws in the WMR Controllers and how they were not designed with gaming specifically in-mind, or at least not the kinds of gaming experiences that devs are now producing. I am now trying to capture VR just using OBS locally on the uber-box, which is now handling duties for gaming, game captures, livestreaming, and VR.
