Magnavox TV with LG surround sound HELP!!

[gottabeme012381]

I have a Magnavox smart TV of course, I have a 300 watt LG surround sound system. My TV doesn't have an optical spot but it has HDMI ports. I had to buy a converter in order to hear my Firestick through my surround sound, but I still can't hear my TV through it. I have tried switching the cables around and tried different settings on my TV and nothing. Can anyone help please?

Would help if you listed brands and models of everything and how things are connected.

TV audio output connects to HTS audio input.
IF the TV out doesn't match the HTS in then you need to converter one to the other.
