I am using the RME Fireface 802 to record a stereo signal for my stream, but unfortunatly OBS won't accept Multichannel audio that contains more than 8 signals.



So, since OBS doesn't like my multichannel feed, I have to give it a virtual stereo signal.



My Question:
How do I create a stereo loopback from 2 selected audio signals from my audio interface?



  • Loopback (input) hardware source: 2 Channels on my Multichannel audio interface

  • Loopback (virtual input)newly created recording signal: Stereo (L/R) audio signal suitable for OBS

Technical details:
Ubuntu 18.10 with PulseAudio and auvcontrol
OBS 23.1.0 (linux)
