Connect a Soundbar to TV Without HDMI or Optical – 4 Ways to Try

To connect a soundbar to TV without HDMI or optical cable isn’t the most technical thing in the world to do. But you do need to know some essential factors. In the age of the internet, we all need to be semi-quasi technicians to save cash. No point paying someone when you can do it yourself.

If your current TV doesn’t have an HDMI port, don’t fret, because there are many ways around that issue. So, here are four of the best ways to connect a soundbar when your TV doesn’t have the standard HDMI or optical connections.

Connecting a Soundbar with Aux 3.5mm Jacks

Aux 3.5mm Jacks

One of the most inexpensive ways to connect a soundbar is by purchasing 3.5mm jack cables. This is one of the best ways to connect if you have an older TV model. And if you don’t know what these look like, these cables have the same connectors as standard headphone jacks.

It’s one of the most direct ways to connect a soundbar to a TV without HDMI or optical cables. Nearly every TV model, especially the older ones, have headphone jack (3.5mm) ports. You can simply plug the cable into your soundbar from the headphone socket of your TV. It’s that simple.

Check out these inexpensive 3.5mm jack cables to simplify your soundbar connection needs…

Pros and Cons of Connecting a Soundbar with Aux 3.5mm Jacks


  • 3.5mm aux cables are a direct way to connect a soundbar.
  • Very inexpensive products and solutions.


  • Stereo outputs only.
  • Not compatible with surround sound systems.

Connecting Soundbar to TV with RCA Cables

RCA Cables

Some older TV models do not even have 3.5mm headphone ports. If this is a major issue that is causing you problems, connecting your TV to a soundbar with RCA cables might be a viable option. It’s also another very inexpensive solution that could have you connected for sound in just a few minutes.

RCA cables are basically audio jacks with two-channel ‘left’ and ‘right’ stereo connections that are color-coded in red and white. They are one of the most effective ways to transmit audio signals. But firstly, check your TV to ensure it has RCA audio output ports.

If your RCA cable only has input ports, you can simply connect the yellow video cable to your TV, and the two-way audio cables into your soundbar. That should be a viable option. So, here are some RCA cable products that are reliable, durable, and highly recommended…

Connecting Soundbar to TV with a Coaxial Cable

Coaxial Cable

There are old TVs… and then there are OLD TVs! If you have a really old TV, the only way to connect a soundbar to TV without HDMI and optical cables is with a Coaxial Cable. This connection is from a bygone era when TVs were mainly used to connect both audio and video from cable networks. Things have dramatically changed.

It’s surprising how many devices still use this type of coaxial cable connection. You will probably need a DVD player or VCR to act as a conduit or a ‘go between’ to connect your TV to your soundbar. This approach might seem a bit complicated, but if it’s your only option, you will have to persist.

How to plug in your coaxial cable…

Plug your coaxial cable directly into your DVD or VCR player output. Connect the other end of the cable to your TV input. You will then need to connect your DVD or VCR audio outputs to your soundbar via RCA cables. By doing this, your TV essentially becomes nothing more than a monitor.

Don’t worry, as it’s not as complicated as it initially appears. As long as you follow these easy steps, you will be wired for sound in no time. All without an HDMI or optical cable. So, check out these recommended coaxial cables currently available to purchase.

The best alternative to HDMI and optical cables are finding a wireless solution to connect your soundbar to a TV. You could use a wireless conversion kit that supports RCA cables or a stand-alone wireless speaker product.
