Need help with Roon/sonic transporter

Installed Sonic Transporter in my system yesterday. Had some network problems initially but they seem to be sorted now. CDs on USB drive plugged in. Only about 1/3 of the CDs show to be recognized. How to make rest show up?
Related question, how to find, look at and select CD for playback?

I need to revise this. NONE of my CDs show up. I think i have not set the device up properly so need explicit instructions on doing that. PLEASE!

Please contact Small Green Computer for help.
