I have been trying to set up my Sonos Arc with my TV which does not have an ARC port. This has proved to be exceptionally frustrating, and pretty much every part of the system owns a piece of the blame. The TV, as I said, does not have ARC. Streaming services only seem to offer Dolby Digital Plus, which doesn’t work over optical audio, and cannot down-convert to Dolby Digital (not plus). It seems there is only one (the HDFury Arcana) box that can split an ARC signal off of a normal HDMI.
Although this all comes together to create a perfect storm of incompatibility, I wan’t to ask here about the design of the Sonos Arc. From what I can tell, most home theater setups have an HDMI input coming into a receiver, which passes sound to all the speakers, and video on to the TV through an HDMI. It seems like the Arc reverses this setup, going backwards from the TV into the Arc, which is effectively acting as the receiver. Why was this design choice made, and why is there no HDMI pass through. Or alternatively, why not be able to accept a normal (non-ARC) HDMI signal? The audio is clearly encoded in it. Could this be done in a future update? Sonos seems like a great company, but it seems there is no route to surround sound, especially Atmos, without a specific TV with an ARC port.
So, my questions:
- Is any of this information wrong? I may be totally misunderstanding something that would make surround sound from a streaming service possible, but I haven’t figured it out!
- I’m very curious as to the design decisions made in the paragraph above.
- Are there other (more affordable?) ARC extractor boxes besides the HDFury Arcana?
- Does Sonos have any products that work as an AV receiver to extract audio to their wireless speakers and pass on video? I was having trouble figuring out how Sonos fits into a home-theater setup these days.
