At first: I use Volumio in that version, coming with the miniDSP SHD STUDIO. The advertisement said, that I contains a licens for Volumio Premium, that means, the support for CD drive rip&play. So I bought the HiFi ROSE RSA780, the only USB drive on the market, dedicated to audio reproduction. Misfortunately the RSA780 wasn‘t recognized under Volumio SHD. And the plugin CD Sound by Nanomesher isn‘t listest there. The people from miniDSP can‘t explain, why. I have updated the old Volumio version on a RasPi3b, wich convinced me, to buy the SHD with Volumio, but now under the Thors release, the CD plugin by Nanomesher is dissapeared. Now I‘m confused, how to mary the SHD Volumio and the ROSE RSA780, which would, of cause, be a splendid couple. Best regards Martin
