I'm only half joking with this low-tech solution: https://www.amazon.com/Retekess-Transmitter-Microphone-Translation-Receivers/dp/B07W7QM1NW?ref_=ast_sto_dp https://www.amazon.com/Retekess-Transmitter-Microphone-Trans... This extremely low-tech solution would give you 10 room audio from a single source (like MPD, but it could be anything at all since you just plug a line-in - your old turntable for example). If the transmitter isn't up to snuff for your huge abode, you could get a slightly larger transmitter that does about 900ft. With 3 transmitters on different frequencies and say 5 receivers dotted throughout the house, you could tune a room to "Dad FM" or "WTF is that racket FM" I seriously considered this for laughs but didn't follow through.
