I seem to have the same problem a a colleague in this topic:
"# How to stream on OBS audio connection’
Sorry for my ignorance (I am not really experienced in usb interfaces, used to mix on an analog mixer with turntables (no dvs).
I read in this forum that other users teem to have problems using OBS as well, so you might know a workaround for this? (also apologies if the subject has already been discusses but I can not find it).
Thansk for your expert advice, all
