Hi Telephony. Unfortunately, no such device shows up in my mixer. Hopefully, the link below works. It's the first time I've used OneDrive.

Still no audio with debut. (As far as the USB input is concerned.)
Edit: Also, I noticed, in another thread with a similar problem, that Tech Support suggested:
In the Options of Debut go to the 'Devices' tab and confirm that "Capture Sound" is enabled.
My version of Debut, (5.06), doesn't have that option on any tab.
