E-arc in general is finicky, so handshake issues aren't exclusive to Vizio. However, I think their firmware/software is worse than other companies, so that just exacerbates things.

If I was you, I'd connect with an optical cable and see if you are still satisfied with the sound and functionality (I'm guessing you will be). If so, keep using with HDMI/e-arc and if that ever craps out, just revert to optical.

That sounds like a good plan as an option as well. Most movies and shows are not streaming in Atmos yet, and this system sounds plenty awesome even on non Atmos movies. I will switch my connection from eARC to optical as a test and then switch it back. I'm still torn on what to do and still leaning towards returning it. But thanks very much for your suggestion.

i bought the new low cost sonos (can't even remember the model now) soundbar and the optical refused to work with my samsung frame so i ended up returning it for the beam which was actually a better soundbar and had HDMI.

of course that was after i generated about 40 posts on the sonos CS forums and got everyone else riled up as well who were having the same issue.

i'm sure they've sorted that out by now but i prefer hdmi since there are other advantages to that over optical.

Am I the only one that just wants Apple to come out with a Center channel "soundbar" and a sub? Then just use the HomePod 2nd gens as a R/L or rears.

Apple seems to have dabbled into "home theatre" sound with the homepods being able to produce average sound from the appleTV. Cmon Apple, take more of my money!

Crazy that optical didn't work since it's just an audio stream, and optical is tried and true AFAIK.

Aside from higher bandwidth for Atmos, the other benefit of HDMI is CEC functionality, but I think that's what causes all the handshake issues.

So if your HDMI eARC connection starts causing a problem, would just a vacant normal HDMI connection on the TV and Soundbar work (and be better than an optical cable)? I assume if a normal HDMI connection works, it would just be a one way connection from the TV to the Soundbar just like any other source to the Soundbar and the TV remote would not be able to control the Soundbar and I assume but am not sure that Atmos would not pass through a normal non-ARC or non-eARC HDMI connection. Can anyone confirm?

EDIT: I think found the answer and it is surprising. If your eARC connection starts causing problems, you could try using both an HDMI cable and an optical cable simultaneously......

"Connect the TV’s HDMI eARC port to the soundbar’s eARC port using an Ultra-High-Speed HDMI cable. In the rare case that your TV does not have an HDMI port labeled eARC or ARC, connect the HDMI cable from the soundbar’s HDMI TV port to any HDMI port on the TV. That connection will handle the video (and possibly basic audio). In addition, you will need to connect an optical digital audio cable to both devices to handle the sound. Connect an optical audio cable (no longer than 5 meters) from the TV’s Optical Out (or OPT OUT) to the soundbar’s Optical In (or OPT IN)."

If in not mistaken, only a TV's HDMI port designated as e-arc (or plain old "arc" for older TVs) will output audio.

My guess is that if you did not use or did not have an HDMI ARC or HDMI eARC port on a TV that you would only require an Optical cable connection to get Dolby Audio (minus Atmos sound) from the TV to the Soundbar. I assume the only reason to connect a normal HDMI port on the TV to the Soundbar in this case would be if you had video sources (BluRay Player, XBOX, etc) connected directly to the Soundbar since you would need to get their video to the TV.

Yes, only reason to use optical and HDMI is if you're using a soundbar in passthrough mode. Not all soundbars do this (none of the Sonos bars, for example).
