For HDMI ARC, you'd need HDMI ARC on the LG. What are the available audio in ports on the LG and audio out on Samsung??

Lg system...Port in for portable devices..AUX input..
Audioout on samsung...optical output

I think hdmi port on lg sound system is not arc..i mean its not written on lg system that which sort of hdmi port is this

Not sure about the HDMI issue.
There's an optical in on the LG, I see.
So, an option would be using an optical audio cable.
