Solved! Soundbar, TV box and Chromecast Issue

[ddk0014]

Hi ppl.

I am trying to connect my Soundbar to work with Android TV box and Chromecast
I have currently plugged in Android TV box and Chromecast via HDMI to TV (not HDMI ARC, TV doesn't have ARC or optical inputs/outputs) but unsure how to connect Soundbar
Only option I could think of is to use Optical (from Soundbar) > Digital to Analog Converter > 2 RCA (output) > TV: will this work or are there any other solutions ?

PS: TV model: TCL 55S4800FS, bought about 3yrs ago
Soundbar, Sony HT-S100F has HDMI ARC and Optical
Here's a photo of back of my TV: https://www.dropbox.com/s/u9mu2tuxx8ng14t/IMG_8871.jpg?dl=0
Thank You

You seem to be mixing up inputs and outputs.
The TV has a coax spdif digital audio output. Get a coax to optical digital audio converter.

and the cables to connect it to the TV and the soundbar.
You may have to turn the output on, the TV speakers off, and change the audio type in the TV audio menu.
