Just thought I should give this some context......
I'm on windows 10, I have an on board soundcard and a separate usb sound adapter on my laptop. I don't know if this makes any difference but I'm using a behringer XENYX 1002B analogue mixer. I have tried numerous different settings with regard to the 'main' soundcard, the inputs and the broadcast course is set to input 1, as per the input from my mixer.
Any help would be very gratefully appreciated.
Many thanks
SJ
