Dolby atmos has nothing to do with 4k or HDR? Correct?
I am going to use a Sony sound bar (2014 model) with the TCL. Where does dolby atmos come into the equation?
How does the tv recognize a sound bar? Is there something in the roku settings I must do to tell the tv to use the sony soundbar?
Hdmi 3 arc? right?
My current Sony tv, sees the soundbar, and will tell me an external speaker is being used...will the tcl do the same?
as long as you have ARC setup in the TCL your fine. if your soundbar has HDMI inputs, it's output will have ARC as well and that should be enabled.
i'm not going to speak to Sony or anybody else, i will say, TCL simply recognizes you have something sound capable and outputs sound to it. not sure why you need something to tell you the external sound source is being used, you should either hear it or not. the choices in the TCL is utilize ARC or tv speakers.
your soundbar, if modern enough, with HDMI will communicate to the tv what it can and cannot support, the tv won't (shouldn't) send something to the soundbar that it's edid has said it cannot support. if your soundbar can't support atmos, it won't decode atmos from the DD+ package. if it supports 2.0/2.1 that's what it will get, if it supports 5.0/5.1, that's what it will get. make sure you know what your soundbar supports and make the audio settings accordingly in the tcl menu. also, you can download the tcl manual and read through it. your questions will mostly be answered there. try that.
you have asked a lot of questions and it's not as difficult to setup as all the questions you have asked.
best of luck, keep us posted.
