In OBS I only use the analog "Line In" as "Mic/Auxiliary Audio" source . Only Track 1 used and no desktop audio capture (I also mute all the other audio inputs)
EDITED:
---------------
So with version 0.2.3 I have this results:
- If I record using the Audio Track option "Track 1", i have no audio
- If I record usign the Source option "Mic/Aux" , the recorded audio is bad (like before).
NOTE: I'm recording the main OBS output at 2160p@25 (NVENC_new) and 2 independent sources at 1080p@25 (NVENC) from 2 x ElGato 4k60 Pro MK.2 capture cards
