Optical cable convert - Panasonic SC-HT520 System

The Sharp LC-32B23U does not have a headphone (3.5 mm) jack. See the specifications here: https://www.cnet.com/products/sharp-lc-32sb23u/ . It has an optical digital audio output. To connect your headphones, you could use a digital audio to RCA audio converter. See https://www.amazon.com/optical-rca-converter/s?k=optical+to+rca+converter for some converters. Then use RCA audio cable to connect to an RCA (2 F jacks) to 3.5 mm F adapter. (If your headphone has a detachable cable, you could use an audio adapter cable with 2 RCA M plugs on one end and the 3.5 mm M plug on the other.

I hope this helps.

If you want to connect a soundbar to the TV without HDMI or optical, you have two options: go high-tech with a wireless connection or mid-tech with 3.5 mm aux or RCA cables. You can also use an auxiliary device to convert coaxial cables to another type of connection.

You probably will get the best result if you use a digital to analog audio converter. Amazon has a number of models: https://www.amazon.com/DA-Converters/b?ie=UTF8&node=3224445011 . You will need to provide the optical audio cable. You connect the TV's optical audio out to the converter's input. Then use the converter's RCA output to the home theater system's audio input.

The TVs HDMI port is only an HDMI input (possibly with Audio Return Channel). This isn't usually resolved by an HDMI-RCA Converter. This converter might have worked to split off the audio signal from a Blu-ray player with an HDMI cable to the converter and then another HDMI cable to the TV and the RCA audio going to the Home Theater system.

Based on the specs from CNET, the Seiki SE322FS does not have an optical digital audio port. There is a coaxial digital audio port which looks like a standard RCA jack. The main difference is that it will be a single output jack, instead of the groups of RCA input jacks (component and composite audio/video ports). See https://www.cnet.com/products/seiki-se322fs/specs/ . See https://www.lifewire.com/coaxial-vs-optical-digital-cable-3134605 for some of the pros and cons for each type of digital audio cable.

Since the TV will be your audio source, you'll need a coaxial to optical digital audio converter. This is one example: https://www.cablestogo.com/product/40018/coaxial-to-toslink-optical-digital-audio-converter-taa-compliant . Note: usually the cables are not included with the converter. Thus, you'll need to get a coaxial digital audio cable separately. A different converter is needed to go from an optical digital audio output to a coaxial digital audio input.

I hope this helps.

Are there any other connector inputs on your soundbar?
If not you may need to purchase a digital to analog converter. Fiio makes one as do many other companies. Easily found on Amazon for about $20.00.
You hook up your tv's RCA audio output to the RCA input on the converter and then the optical cable to the converter then to the soundbar. That's how I would solve this issue.

It sounds like your CD player does not have an optical audio output. If so, you will need to get a "Digital to Analog Audio Converter". You can find them on eBay or Amazon for as little as $10. Connect your CD player's analog/RCA-style stereo cables to the converter.Then connect the converter to your receiver with a single optical cable.
