We bought a Sonos Beam to replace our B&O Beolit '12 Airplay enabled speaker in the living room. We are using an Apple TV (4. gen) connected to a projector. So far the audio of video content was streamed to the Beolit via Airplay from the Apple TV. We liked this because of the cablelessness. Now Airplay 1 wasn't always that stable hence the upgrade to the Beam beacause of Airplay 2 A/V sync capabilities. Now we have a problem that content when streamed via an Macbook e.g. from Youtube via the Airplay option in Safari (same with just airplay monitor sync or Beamer app) to the Apple TV we have image but no audio anymore. Tried to create a little table below to explain the problem. #4 is the problem with no audio. Is this a general Airplay 2 problem (same with Homepod?) or some problem with the Sonos implementation of Airplay 2?
