How to Use/Connect a Soundbar Without a TV?

It is straightforward; several connectivity options make connecting a soundbar with many audio devices possible.


8 out of 10 soundbars feature a 3.5mm audio jack or AUX port. AUX is one of the most convenient, straightforward, and reliable connectivity modes. One of the best points about AUX is it transmits audio signals without leaving the tiniest hint of an audio drop behind.

Even beginners can get their hands on the AUX cable- thanks to its user-friendly design. The cable features a connecting pin to each end. Another best point about using AUX cable is the wide availability of devices. Whether a smartphone, laptop, PC, or gaming console, you can easily use devices.

  • Connect the input end of the wire to your device, computer, mobile, or laptop and the output end to the soundbar.
  • Secure the connection before streaming music.


Since we live in an innovative world, why not try out the most creative way to use your soundbar- thanks to Alexa? As you know, Alexa is an AI by Amazon allowing you to control your internet-connected devices with voice commands.

This cloud-based AI is effortless to use and operate. Its performance efficiency is also second to none. To use your soundbar via Alexa, you need to do the following;

  • First, connect your soundbar to the SmartThings app. Ensure you’re using the current version, not the classic.
  • Now, change the soundbar name to something simple for one-glance recognition.
  • Download the Alexa app on your smartphone and sign up if you don’t have an account.
  • Direct to the Main Menu from the dashboard, then the Skills & Games option.
  • Enable Samsung Wireless Audio for your soundbar.
  • Now, tap on Discover devices or say “Alexa Discover Devices.”
  • Search for your device (SmartThings device) and tap done.
  • Now stream your favorite music over your voice commands.


While people are still getting their hands on Bluetooth, this is the best connective mode once paired- thanks to its convenience and speed. Another best point is the goodbye to wire mess.

You can connect your laptop, smartphone, tablet, or other speakers to your soundbar without a cable while relaxing on your couch.

However, one major drawback of Bluetooth connection is the distributed signals in interference with another device in the surroundings. To connect your soundbar to your desired device via Bluetooth, follow the below steps;

  • Press & hold the Source button until the LED display BT.
  • Now press the Pair button on the remote controller to enter the BT Pairing Mode.
  • Now switch ON the Bluetooth pairing mode on your desired device and click the Pair & Connect option.
  • Ensure to keep both devices close and others away to prevent signal interference.


You must have seen the color-coded ports on the back while inspecting your new soundbar. If your soundbar and the sourcing device have RCA ports, connect both via RCA cables- matching the color codes.

RCA ports are standard, from the old TVs, record players, and DVD players, to the latest model soundbars. Despite using the analog method for audio, RCA still delivers satisfying stereo quality.

  • The RCA cables come in two standard colors- red and white. Connect the white cable to the white port and the red cord to the red port.
  • Ensure the output end connects to the soundbar while the input end to the device.
  • Connect both devices with a power source and stream music.

Digital Optical

Digital Optical connection is a must feature every soundbar has. Like HDMI, the Digital Optical transmits audio data without compressing it, producing high-quality audio signal transference.

The unique point of Digital Optical audio signal transference is the use of laser light and fire optic cable. However, most users complain about dropping signals, not knowing why. Keep the wires tightly inserted on both ends to prevent the escape of audio signals.

  • Connect the input end to the sourcing device while the output end to the streaming device.
  • Again, ensure the pins are inserted tightly.
  • Use high-quality cables for better efficiency and audio quality.


It would be a lie to say you have yet to try the USB connection. Along with HDMI and Bluetooth connectivity mode, USB is our most common option. Besides being highly common, the quality USB cables offer is second to none.

As you know, USB cables are digital audio cables. These digital audio cables allow the transference of complex audio signals with high efficiency and frequency. It eliminates the need for compressing the audio data.

  • Get a USB type A, B, or C depending on your connecting device’s supporting ports.
  • Connect the input end to your mobile, laptop, or PC and the output end to the soundbar.
  • Ensure both devices are compatible before streaming music.


High-definition Multimedia Interference, or HDMI, is another standard connectivity mode. The HDMI transmits uncompressed audio/video signals from one device to another. Since HDMI delivers uncompressed signals, the quality is always on point.

Even though HDMI performs as a transmitter of digital audio signals between devices with high-quality assurance, while optical cables do the same, HDMI does even better regarding high-resolution audio signal handling.

As reliable and high-quality as the connection is, it is limited on devices. You can’t connect your phone or tablet via HDMI- only some devices have an HDMI port. Have an inspection of your desired device before buying a new HDMI cable. To establish the connection;

  • Press & Hold the same Source button to launch HDMI connectivity mode.
  • Now insert one cable end into the soundbar while the other end into the other device.
  • Stream sound to test the audio quality.

How to Choose Right Soundbar for Non-TV Use?

When you want a soundbar and do not want to connect with your TV, a few considerations help you pick the best soundbar for non-TV use.

Sound Quality

In addition, the driver size can also make a difference the larger drivers produce louder and might be better sound than a small one.
