Why can’t i get atmos with my Arc on vizio m556-h4?

I recently bought an Arc, two bookshelf speakers and a sub. I have it going through an 8k HDMI cable to my eArc port and eArc is turned on through the settings on the tv. When I try to play music or movies with atmos, it never says I’m getting atmos on my app. Please help.

Neither of my two Vizios allow passing of Dolby Digital Plus or Atmos on HDMI inputs, although they do play Dolby Digital Plus on the internal apps. Took a couple of contacts to Vizio support to figure that out. The newer one is a P75-F1. I’ve ended up getting an HD Fury Arcana as a result. 

I don’t think I need that. This TV has eArc.

Glad to hear that, but my faith in Vizio’s ability to properly implement this kind of thing is relatively  faint, given the fact that while my TV is capable of DD+ from internal apps, it can not handle that format from HDMI inputs. Why makes zero sense to me, as the device says it has ARC. It might be worth double checking, as I had to do, with Vizio’s CS group.

Would I have to get a FireStick 4K then?

Since your TV is equipped with eARC, it should work. If it doesn’t, you can always return it.
