USB put no longer working

[Bikesnbeats]

Can I do something to bring this back? It no longer selectable on the app or the WiiM’s screen. USB cable is connected to my DAC.
Thanks.

This might normally imply that the dac isn't on or isn't set to its usb input.
Presumably you tried unplugging / reconnecting the usb cable or rebooting the ultra / dac.
Out of interest, what dac?
