Configure USB output on nRF5340 Audio DK


I was able to setup nRF5340 Audio DKs as gateway and headset, test the USB audio input and enable the Walkie Talkie demo. But in both cases I'm using I2S/analog headset out. 

How can I enable audio output over USB on the nRF5340 DK? From this link I noticed that unicast client supports USB audio out. Is this correct, and if so how can I enable this path?

Thank you
