I'm trying to record some game footage and include some talking but I can't get audio to record from multiple sources. I have the game audio coming into the system via a loop back cable into line-in which works I also have a Bluetooth headset which can work for my voice on its own But I can't record from both simultaneously since Pulseaudio only lets me select one My ideal setup would be audio output via BT headset I can hear the line-in input also via module-loopback which I already do but I see problems if the voice is multiplexed with since I don't want voice looped back to the output the OBS recording software records both line-in and voice (BT) either via some virtual multiplexed virtual input or being presented with multiple input options from Pulseaudio (prefered over virtual) I tried going through the list of modules on the wiki but couldn't figure out how to do anything.
