Hi really struggling with this. My digital dj program which uses my external soundcard as an out works fine with obs (on the same laptop) but want to do a live feed playing vinyl, via a mixer and external soundcard. Sound going into my radio buffer ok. Obs recognises my soundcard but try as I might I can't get any audio signal into obs watched many tutorials but nothing I try seems to work, anyone else have this problem or know how I can sort this out?
