Without knowing the exact model numbers of your equipment i can only advise so far. I am again presuming that you are talking about a soundbar and woofer? The usual and best way to connect the soundbar would be to use the optical digital connection. It looks like a small square port with a little flap on the back of the TV / Soundbar. You should be able to find fairly easily as it will be emitting a red light behind the little flap. The same connection will be found on the rear of the soundbar. Use one of these (or similar) to connect both together: https/www.amazon.co.uk/AmazonBasics-Digital-Optical-Audio-Toslink-Black/dp/B00NH11H38
You will need to check in the sound menu of the TV that the sound output is set to either S/PDIF or optical output (most likely is S/PDIF being that this stands for Sony/Philips Digital Interface Format.
