I already have a Sonos surround/home theater system built on a Playbase, sub, and two One rear speakers. I got this set-up to replace a failing Bose wireless 5.1 surround system, not realizing it was dependent on an optical sound input, with no HDMI input option, and have never been fully satisfied with it. So I was excited to learn about the ARC (and discover what the HDMI (ARC) input on my Samsung TV is for). I ordered a white ARC soundbar from Amazon on June 20. Amazon showed the release date as July 6 and promised delivery by July 8. Looking forward to it, I upgraded to the Sonos 2 app and read all the set-up info online to minimize headaches on arrival. July 6 came and went with no shipment notification from Amazon. Ditto for July 7. Today I received a notification that shipment would be delayed until sometime between July 30 and Aug. 19. I’m patient. I can wait. But I’m disappointed, and wondering what’s the holdup. Is Sonos so flooded for orders for the ARC soundbar that they can’t keep up? Should I buy their stock?
