I have an older Mac Mini, A1347, from late 2014, hooked up to my home theater system for some games on it. Apparently this model doesn’t send audio out through the HDMI cable. My system in that room uses a Playbar, two Sonos 1 players, and the woofer (forgot what it’s called).
When I try to use AirPlay so I can play the audio from this Mac through my theater sound system in the same room, that system (based on the Playbar) is not on the list of Sonos devices I can use for playback. All the other Sonos devices in that building and in the house (all on the same LAN) show up, but not the theater setup.
Is this a solveable problem or is there some reason the Playbar and combined system of 4 speakers can’t handle AirPlay when all the smaller devices can?
