🎶 Music Connectivity
  1. Sonos’s Apple Music integration is unreliable and AirPlay doesn’t work well across multiple speakers, which undermines the whole‑home audio experience.
  2. SonosNet surrounds can seriously interfere with 5 GHz Wi‑Fi; removing surrounds noticeably improved network speeds.
  3. Support and recent app changes have worsened the experience, so using a traditional AVR and quality speakers with an Apple TV is a practical alternative, while Sonos Amp or soundbars can still work for specific setups.
