But, the question is, how to connect the soundbar to the cable box? Do not worry; we will discuss this subject in this essay. We’ll tell you in simple words how you can connect your soundbar to the cable box. 

Please make sure you read this article from beginning to end to understand it completely. Without further ado, let’s get to the topic.

How to Connect Soundbar to Cable Box?

The ideal location for a soundbar connection is the HDMI input on your TV. Why? It is the one that comes with the cheapest wires, is very simple to use, and can process Dolby Digital technology for good sound. Therefore, if you want the purest audio possible in your TV, HDMI is your best choice.

Additionally, you might require an HDMI connection if you’re streaming material that uses Dolby Digital, Dolby Atmos, or DTS:X in order to fully decode the sound supplied by these technologies. 

That’s because HDMI ARC can produce the kind of crystal-clear sound that other input connections, like digital or analog, can’t. According to all the testing we’ve conducted with various soundbars, The HDMI and optical digital input connections are the finest methods for attaching any soundbar to a TV.

How to Connect a Soundbar to TV/Cable Box with HDMI ARC

The proper audio cable must be used to connect your soundbar to your TV in order for the two devices to function properly. You should choose HDMI ARC (audio return channel) over other connectivity options if the soundbar provides that feature. 

The Samsung HW-J450 is an illustration of a soundbar with these features. The HDMI ARC port is located at the rear of your soundbar. Most of the top Dolby Atmos soundbars are equipped with an HDMI Arc port as well.

You may easily connect the soundbar to your TV via the HDMI connector, but more on this later, assuming the HDMI cable of the right length was included in the box when you made your purchase. 

You might need to buy a new HDMI audio return channel cable if you don’t already have one. However, this particular cable is among the most reasonably priced available, so it won’t set you back much money. Make sure it fits snugly once you connect it to prevent any technical problems. 

The cable’s opposite end must then be connected to your device (Your TV or your cable Box). The “out port” and “in port,” respectively, are the HDMI ports on the back of your TV and soundbar.

Activate your soundbar and television. If you have a remote control, you must first pick D.IN by pressing the source button. Now, your soundbar should be connected to your cable box. Wasn’t that too easy? 

But, what if you don’t have an HDMI cable? Can you still connect your soundbar to your TV or your cable box? 

Fortunately, the response is yes. That is possible. You have a few options for how to connect your soundbar to your TV or cable box. Take note of the techniques described below.

1. Connect Your TV/Cable With Your Soundbar Using Bluetooth

If messing with cables bothers you, Bluetooth allows you to go cordless. It is a simple connecting approach that does not clutter your interior setup with ugly cords. 

One of the best features of a Bluetooth connection is that you won’t have to get on your hands and knees to look for the right input. This is one of the unpleasant things about any wired configuration, especially if your TV stand is closer to the ground.

Plus, since Bluetooth is already present in your gadget, you won’t need to check to see if the cords are included in the box. You must first make your gadget “discoverable” before attempting to connect it to your TV. This implies that you can locate your device when using other Bluetooth-enabled devices to look for it.

After completing that, you may use your TV to search for the name of the device. Although it might not be immediately clear to you, the label (or name of your item) usually comes after the model number or brand name.

Your unit can then be “found” and the two devices can be connected. Usually, the audio source device is where this is done. Simply choose the name of your device, then wait for audio pairing.

2. Connecting Soundbar to Cable Box Using Optical Cable

The digital optical cable ought to be included in the package and be connected similarly to the HDMI cable. 

  1. It should be included in the majority of top-notch soundbar devices, so it’s unlikely that you’ll need to buy one separately. Plug one end of the cable into the digital audio “out” by locating the correspondingly designated plug on the back of your TV.
  2. The digital audio “in” connector on the soundbar must now receive the opposite end of the digital optical cable. To avoid any quality loss in the audio, make sure to fully enclose the optical cable on both ends. 
  3. The cable connection has been verified, it’s time to turn on both devices. Once your TV and soundbar are both powered on, Press D.IN after selecting the Source Option on the remote control or the side of the soundbar. Now, you should be able to use optical digital audio to link your TV and soundbar.

Overall, not just your soundbar but any external device can be connected to your TV using this method. You can also try connecting your gadgets with an HDMI CE for single-source control.
