Hi!
I’m currently building a few Internet Radios using Raspberry Pis, some old Tube Radios, converter cables and, of course, VOLUMIO!
So far all is working great, still twiddling around a bit, so I will probably post some questions soon in the Troubleshooting section 
Thank your for all the work that has been invested in this project, one of the greatest I have played around with so far!
Greetings,
Claude
