Chord Qute EX does not find by Roon core on Linux PopOS

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:

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.
