Unable to connect Edge via USB to Lyngdorf TDAi-2170

I have installed a TDAi-2170, been unable to get sound from USB input on the amp. Roon shows USB output to Lyngdorf usb device.
I’m able to play music / via the HDMI connection from my Blu-Ray.
Roon shows as playing music, however no sound from amp on USB input.
Help in resolving this greatly appreciated, otherwise I’m in for a frustrating weekend.

Have you set up the Edge via myantipodes?
