Description of Issue

Your OS (PopOS) needs a suitable driver to talk to your DAC over USB. Does the DAC work for you if use some other playback software on your Linux machine? If not and you can’t find (or compile) a suitable driver, you may have to find other ways to connect your DAC to Roon (soundcard with digital output, Roon Ready streamer with support for your DAC).

Have a look at the thread below too:

microRendu does not see Chord Qute EX

I am trying to connect a Chord Qute EX to a microRenu. This DAC is not seen by the microRendu and therefore can not be seen as a ROON Endpoint. If I substitute a different brand DAC it will see it, lets me do the DAC Diagnostics and can be seen as a ROON endpoint. If I connect a X-core USB to SPDIF converter to the microRendu and then connect the Qute EX DAC via the coaxial input it will work. I believe the issue is that this DAC selects which input it uses based on which input sees a signal.…

PS: @moderators please place the this where ever you think it fits best, but I believe its unlikely that the support category is the right place for this OS/driver issue.
