DAC connected to Pi4 with Ropieee no longer showing in audio

Raspberry Pi4 is showing as a Roon bridge in Settings>About.
Nad D 7050 connected to the Pi4 via USB no longer shows in Settings>Audio.

This set up has been working for months without issue. I think it lost connectivity around the time of the Roon 1.8 upgrade.

I have rebooted the Pi, toggled the USB output in Ropieee off and on, turned the Nad off and on and replaced the USB cable to no avail.

Roon V1.8 running on Mac and iPad
Roon Bridge 1.7 build 571
Raspberry Pi4 with Ropieee V 3.113
Nad D 7050 with latest firmware V 1.6.7

You didn’t mention if you rebooted the Roon server?

Send a feedback to Harry here from the advanced tab

Yes, I rebooted the Nucleus server

Do you mean the advanced tab in the Ropieee web interface?
