We just had our first SONOS ARC delivered and have started putting it through “real” use. Unfortunately we cannot even get out of the starting gate. The connectivity limitations make it near impossible to use any differently than our 2 aging SONOS PLAYBARs.
We have tested using several different devices including 4 smart TVs (Sony and LG with eARC and ARC), Blueray player, Broadband TV set-top box, Media PC and Apple TV. Some of these were just to ‘see if it works’ and not used normally.
Here’s the catch - the extremely limited audio formats make the SONOS ARC impossible to use via an ARC or eARC.
