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:
Thank You
