I have been playing Sonos music to my hot tub via a Sonos Port RCA output that is hard wired through a mini plug at the other end that is plugged into the auxiliary input for the tub JBJ speakers - worked great. But the hot tub motherboard burned out, and the new updated hot tub motherboard will only accept a Bluetooth signal to run the tub speakers (no more hardwiring).
Question. Is there a way to now send a Bluetooth signal to the hot tub speakers through the Sonos Port, or maybe some other way ?
