I love it!
It gets used every day at my house, and i have build a ryobi battery powered portable speaker for when i am working outside. I typically use RPi3 and RPi0, with an amp-hat to power speakers.
does anyone else use it? and if so, what is your setup and have you found any decent hardware/solutions?
it sounds like you use it for sync’ing if you have multiple clients?
how are you getting audio out of the rPi’s?
