RESOLVED: This method bypasses OBS ASIO capture entirely by feeding a solo DAW, via your headphone buss into an external USB Xonar U7 Mk 3 audio device, allowing OBS to record live screen and live DAW audio in full stereo, without ASIO plugins, virtual cables, ReaRoute, or other deficient, frustrating, compromised alternatives.
Requirements:
1x external USB Xonar U7 Mk 3 audio type device.
Your locally installed and assigned ASIO device (proprietary or 3rd party).
1x 3.5 to 3.5 (or 3.5 to 6.5) stereo cable.
2x mono, or 1x stereo cable/s to return to your DAW channel/s.
Desk Setup:
Configure a Stereo Master send on your DAW mixer (assign 1x full stereo or 2x mono channels) say 7+8.
Solo the channel/s to assign them to the headphone buss.
Connect your 3.5 to 3.5 cable from you headphone send on your DAW desk, to the line-in on your external USB audio device.
Connect 2x mono, or 1x stereo cable/s to return to your DAW channel/s, say 9+10.
OBS Setup:
Add 1x Audio Input Capture and assign your USB device to it.
Add 1x Audio Output Capture and assign your local free Audio device to it.
You should now have level indication on your OBS Audio Input Capture source.
