Graham Norbury gnorbury at bondcar.comHonestly the best "documentation" is going to be the *example.json files found in the apps directory. A single "one trunked system with 3 feeds" can be seen in p25_example.json. You don't have to use liquidsoap if you don't want to; there is the built-in audio player and also the stand-alone helper app "audio.py". That said, we moved away from recommending darkice because of reliability issues with the snd-aloop driver on Raspbian.
