SteamVR has an "Audio Mirroring" function that lets you mirror what the headset plays on its speakers to an additional audio device, I have that routed to one of the USB channels on the RCP2, so anything I hear in VR is reflected in the mixer, and should be able to be brought directly into OBS for the stream audio. I got a Stereo 3.5mm-to-XLR cable plugged into the Line Out on my MoBo, that handles Spotify for the music bed. I can't discern any significant loss in quality, but being the music bed, I'm not too concerned if there's any extra latency from the repeated back-and-forth digital-analog conversions as I don't consider BGM to be a latency-critical component to my workflow. I'm still trying to figure out how to get the SteamVR headset mic (USB) to integrate with the mixer. I have a mono 3.5mm-to-XLR cable that I'm trying to figure out if I can make work, if I can get the USB mic to be treated like an XLR mic I can leverage the full suite of capabilities the RCP2 provides. I consider this to be a slightly more latency-critical task than the BGM because fine-tuning audio offsets in OBS is a drag lol
