[SOLVED] Samsung + Fire TV + Sound bar Arc help

[dovedescent7]

I have a 2011 D series samsung tv with one ARC port. Its a un55d6420 model.
I have a fire tv second gen box going to a 2019 samsung soundbar via hdmi then soundbar to the TVs arc port.
The problem is, the sound is all over the place, volume high and low for the same series and wakes up my wife.
I noticed the soundbar wont star on TV ARC mode, but instantly and always goes to HDMI mode vs TV ARC mode.

Is it my cables? or is this not possible?
I want Arc to work from Fire tv to soundbar to Arc port on Samsung tv.

Any suggestions?

fire tv is hdmi input only, no arc hdmi
tv to soundbar should be in arc ports

rest should be handled through tv/sounbar sound settings
