Solved! Logitech 506Z speakers and TCL Series 5 TV. Speakers are supposed to convert 2 channel sources to 5.1 but don't?

I've used both the 3.5 mm jack and RCA audio cables to hook up the speakers to the TV. The sound compared to my older TCL TV isn't as good. (That surprised me.) When I looked at the ports I noticed an ARC port. (My older TV didn't have that.) Would an ARC to analog adapter help get better sound? I'm not sure how those work. I saw similar threads on this topic that are older and the recommended adapters/converters aren't available anymore. I, also, have a Sony blu-ray player that has two audio out ports. One is HDMI and the other coaxial. But, I don't know if I can run my TV audio out through that to the Logitech speakers. Also, I would consider getting a receiver if that is a good option for better sound.

These are the speakers: https://www.amazon.com/Logitech-Surround-Theater-Speaker-System/dp/B003VAK1FA
This is the TV: https://www.bestbuy.com/site/tcl-50-class-led-5-series-2160p-smart-4k-uhd-tv-with-hdr-roku-tv/6358908.p?skuId=6358908
This is the blu-ray player: https://www.bestbuy.com/site/sony-streaming-4k-ultra-hd-hi-res-audio-wi-fi-built-in-blu-ray-player-black/6188345.p?skuId=6188345

I've been upgrading my entertainment equipment a little bit since we're spending so much more time at home.

Any suggestions are appreciated.

The BD player is irrelevant in this case.
Those speaker will only produce surround sound if you have a 5.1 analog source (like the three audio output jacks on a computer).
To get 5.1 out of them you would one of these
https://www.amazon.com/SOUTHSKY-Converter-Decoder-Support-Digital/dp/B08B1MYDXQ/ref=sr_1_4?crid=1CUXUFY2WEXTX&dchild=1&keywords=optical+to+5.1+analog+converter&qid=1595531328&s=electronics&sprefix=optical+to+5.1+analog+conv,electronics,828&sr=1-4
which would connect to the SPDIF optical audio output of the TV and to the 5.1 inputs on the speakers. This is a fixed output so the TV remote won't control the volume; the speakers volume control will do that.
