FM topic is back

Time to sum up all that we know about FM support for Raspberry Pi and make decision. 



To be honest there is no good solution for both, DAB and FM frequencies. All solutions that cost more than 40-50$ are not interesting for us. We wanted to give a try with uGreen, however there is no support for FM and after few emails exchange looks like they are not interested in further development. Our opinion about SDR dongle stays the same - too high resource consumption. 

Seems like, for know, the only solution would be to use Si4702/03-C19 wih Worldwide FM band support and stay with welle.io for DAB and DAB+.

This also means that audio sources have to handled manually by user. For now, development of audio-mixer is out of scope for us.

As always, let us know your thoughts.
