I’d like to order the new sonos arc and pair it with my LG oled C8PUA.

it seems LG is not going to update these tvs to the eArc standard (bums). What exactly does that mean? Im i just throwing money away here? I’d live to get a good solid Dolby atmos surround sound system going. Will the experience be any good? I’m not a super audiophile- but i do live a great sounding movie. I mostly watch from Netflix/amazon.

thanks!

If you have HDMI-ARC and not eARC, you will get DD+ with Atmos, which is what the Fire TV 4K Stick and Roku 4K Ultra use. Ditto most streaming apps on the TV. Nobody really knows what the deal is with Apple TV, but it appears it requires eARC to get Atmos. I’m sure we will find out more when the reviews come out and/or the Arc ships.

so it sounds like it will be great but not prestine. Is that a fair assessment? Like I said I want REALLY good surround sound - I’m not looking for perfection

That would be correct. DD+ is still great, and if you are streaming and not playing 4K Blue-Ray, it’s the best you can get. The fact is, there are very few eARC sets on the market, so you aren’t alone.

Not sure you’d ever get pristine with a sound bar, you’d probably need to invest a lot more money into a true home theater solution. My suspicion is that with the Sonos Arc, you’ll be hard pressed to tell the difference in sound between HDMI ARC and eARC.

LG doesn’t update old models. You need to buy a CX

I can confirm using Apple TV, I get Atmos out HDMI-ARC from the C8. This is working for me right now:

ATV 4K > C8 HDMI-1 > C8 HDMI-ARC > Vizio SB3512-F6 (HDMI-ARC)

So, there's no reason to think this would not work with Sonos Arc? Desperately want to dump my Vizio for a number of reasons (but not due to sound quality). The single HDMI port on the Sonos Arc seems an inexplicable design mistake.

Because it’s not an HDMI port, it’s an HDMI ARC port? How many TVs would you want to connect to a single Arc?

It’s not about # of TVs; it’s compatibility with existing devices. At this price point, it should have pass-through, as does my crappy Vizio. The lack of HDMI-In seems to greatly limit the audience for the Arc.

Airgetlam

Ah, then you want it to be an HDMI pass through device, and not be an HDMI ARC device. I understand.

How many HDMI input ports should it have? Just one output port? Does that mean the Arc and Sonos software would need to support a selection method for which HDMI port is in use? How does your Vizio handle this?
