There's a table at the top with test results.

Regarding the test - "To test for Dolby Digital 5.1 passthrough via digital optical, we connect a Blu-ray player to our TV via HDMI and play the 5.1 audio test found on the Spears & Munsil Calibration Disc, outputted via Dolby Digital 5.1. We then output the TV’s audio to our 5.1 receiver via digital optical and see whether the receiver receives a 5.1 signal, or if it is downgraded to 2.1."

I doubt that Sonos test any TVs for this and don't see why they should. My recent experience suggests that Panasonic TVs don't pass through from an HDMI source out over optical, but I'd be interested if others have had different experiences. Sony seem to have always been generally OK.

Virtually all new TVs have ARC HDMI now but that tells you nothing about DD5.1 passthrough.


Surely they should test it as that's the only way people can get the speakers to work as they should? If they want to claim that you only need one optical cable for it to work then a rough guide would help loads. I've seen that thread, as I say the TVs on it are pretty much all discontinued. I just don't want to be spending another £600 on something that might not even work!


I don't think you've thought through the practical difficulties here.

If they put a stake in the ground today there would probably be several thousand TVs to test - They would basically need to test every TV on the market and from every factory and all the variants thereof.

By the time they had finished the list would be out of date.

Ask your retailer when you buy the TV and make it clear to them you will return the TV if it doesn't pass through 5.1
It isn't the only way. First, most Playbar users just have a Playbar and aren't interested in surround sound. Secondly, there are workarounds involving switches. I am not trying to defend Sonos or the Playbar, just stating some facts.

That thread may be old. It isn't four years old as you stated and it has recent, relevant posts.
