Easiest way to get radio into Devialet?

[mangolego]

On my previous amplifier I used the line-out from my basic Roberts radio.

But now I've wall mounted my Devialet I wanted to keep the area nice and tidy, so wondered if anyone knows of a simple solution to get radio - maybe an internet service via a little Pi or cubox type thing into an optical?  I'd want to be able to control it from an iPad really, and not mess up my Roon setup (which is connected via USB).

Any ideas?  

I dont listen that often and not that worried about SQ really, just for casual background listening, but want something that isn't going to end up needing a lot of messing about with.

(Apologies if this is the wrong section - wasn't sure where best to put it)

What I do is, I go on the web page of my radio station with my computer and use there live streaming and I send it to wi-fi via my Devialet air. Very simple and efficient.
