I own a professional music studio & production facility… audio is routed through our facility using our Dante network which integrates seamlessly with our existing network switches/infrastructure.
Dante is quickly becoming the state-of-the-art, industry-standard for professional digital audio routing & a lack of Dante support for Sonos is the only thing stopping us from going “all in” on Sonos for our general facilities. Dante is Ethernet based, so it should in theory be possible to add compatibility with the Sonos Port via a software update
Also – POE powered Sonos speakers would be A+++
