In every home theater room. The soundbar is mostly available. To get the immersive cinematic sound from the soundbar. Also, to get the feel of a movie theater. So in this article, I am going to tell you how you can connect your soundbar to the projector.

For this, you will need two certain things: the right port and the right cable to connect. To get the audio output from the projector to the soundbar. 

Apart from the connection. We will also know the good position of the soundbar to get the rich sound from the soundbar.

So let’s begin today’s article. Without wasting any time.

What is t he first thing you should look for in the soundbar to projector? 

Let’s pay attention to the two important things: port and cables. As I said in the beginning. Before you start connecting the projector and soundbar.

Make sure when you choose the port in your video and audio devices. Both have the same output and input. In the exception case you won’t need about this we talk later. When we start connecting both the projector.

But in most cases, you should have both the same. And also have good quality cable. So you can get the best from your soundbar.

So these are those things you should check before you connect both devices. Now let’s see what settings configuration you have to do on the projector and soundbar. To hear the voice, from the soundbar.

Things you should know.

An important setting you have to do. You have to choose the audio output settings on the projector. And audio input settings on the soundbar.

You have done it on both video and audio devices. Or both devices automatically detect the output and input audio. But if not you have to manually select the output and input audio options. On your both video and audio devices.

You have to do this process with your all cable connection. To hear sound from the soundbar.

There is a special instruction for the HDMI ARC. If you are going to use the HDMI ARC you have to enable the CEC on your projector. And CEC stands for Consumer Electronics Control.

Which will be the good HDMI cable to connect?

It depends. How much HDMI cable you are going to use to connect your projector and soundbar. For longer than 20 feet you have to go with the fiber optics cable.

And for the short distance, you should buy the certified premium HDMI cable. So all these types of HDMI cables. I will suggest the long and short distances. You should go with.

Where to place the soundbar?

To get the best sound from your soundbar. You have to place the projector in the right place. It’s also very important when you have a Dolby Atmos soundbar.

So what will be the right position to put the soundbar:

You should put your projector at the center and below your projector screen. And if your projector screen is transparent. You can put your soundbar behind the projector screen. It will also be a good option. 

So these are the two ideal places where you can put your soundbar. To get the best audio from your soundbar.

How to connect your soundbar to the projector?

So here we are at the main part of the article. Where I will tell you how you can connect your soundbar with the projector. With different wired and wireless ways.

It will be step by step tutorial. So you don’t need to take worry. There will be a complete connection between both devices. So let’s start.


HDMI ARC (Audio Return Channel) is the best way to connect your both devices. Because it gives you a richer sound quality than any other cable connection. So if you have the option available to connect with the HDMI ARC. 

I will suggest you go with the HDMI ARC. And yes. When you connect with the HDMI ARC. Make sure you are using the HIGH-speed HDMI cable so you can get most of the best things from the HDMI ARC.

So how you will connect the projector with the soundbar. With the HELP of an HDMI ARC port.

  1. Off your both devices.
  2. Take the HDMI cable.
  3. And find the specific HDMI port. Where HDMI ARC will be printed near to the HDMI port. Find this type of port in your both audio and video device.
  4. When you find them, connect one end of the HDMI cable with the HDMI ARC port of projector.
  5. And the last end of the HDMI cable goes into the HDMI ARC port of the soundbar.
  6. And turn on both of your devices. Make the configuration of audio output and input. On both devices. If needed. 

Before you start to connect, listen to this last thing. If your soundbar is 7.1 channel. Then HDMI ARC will downgrade it to 5.1. If your soundbar is already 5.1, then ok. No need to worry about the downgrading in the sound.

Optical Cable or SPDIF Or Toslink 

Another second option to getting the richer sound on your soundbar. So let’s see how you can connect your projector and soundbar step by step. With the Toslink cable.

  1. Turn off both devices.
  2. Take the Optical or SPDIF or Toslink cable.
  3. And head towards and find the Toslink/SPDIF port in your projector as well in the soundbar. When you find the Toslink/SPDIF port. Move for the next step.
  4. Plug your SPDIF cable with both devices. One end of the SPDIF/Toslink cable will go in the SPDIF port of the projector. And the other will go into the SPDIF port of the soundbar. 
  5. Now it’s time to turn on both of your devices. And make output and input audio configuration. If needed.

So that’s how you will connect the audio with the projector. By using the Optical Cable or SPDIF Or Toslink. But here some people have a dilemma. Related to the no of cable. 

When they connect the projector and soundbar with a different cable. Example: one optical cable and another HDMI cable. By using the av receiver.

Here the question comes to the number of cables. A number of cables Do you need? One HDMI cable or two HDMI cables. And vice versa for the optical cable. 

Here the answer will be you will need only one piece of Optical cable and one piece of HDMI cable. To connect both audio and video devices.

Some people have this kind of question in their minds. When they connect the soundbar with the optical cable. And also using the AV receiver and HDMI cable. I hope they got their answer.


This is the most common cable we going to use. When you are connecting the soundbar and projector. Because most of you guys use headphones and earphones. Once to connect with their smartphones. 

You will not get good sound quality with this cable. Like optical and HDMI ARC cable.

So let’s see how you can connect with this cable.

  1. Turn off your both devices.
  2. And find the aux port in your both devices. And I know it will not be a tough job to find the aux port in both devices. Because we all are familiar with this port.
  3. And when you get the aux port. Take the aux cable connect the one end of the aux cable to the projector. 
  4. The last end of the aux cable will be connected with the aux port of the soundbar.
  5. Now turn on both of your devices. And make the configuration of audio input and output. If it’s applicable.

And there you have source device audio on the soundbar.

Bluetooth Or Wi-fi

These are the only wireless option available. With we are going to connect the soundbar and projector. Bluetooth or Wifi depends upon your projector type. Which type of projector you are using? So let’s see how to connect:-

  1. First, turn on your projector. If it’s not.
  2. And make your soundbar in the pairing mode. 
  3. Now in your projector. Go to your projector Bluetooth or wifi settings. And on your Bluetooth or wifi. And find your soundbar for the wireless connection. 
  4. When you get your soundbar option. Click on that option.

And here you have connected your projector wirelessly with the soundbar. In a few simple steps.

But there are some cons of the wireless connection with the soundbar. When you connect your projector with the soundbar. You may get the sync issue.

In your audio and video. This is the most common issue. When you are playing the games. It will not affect that much those people. Those are watching movies and listening to music? 

But you won’t get rich audio like. HDMI ARC and Optical cable.

Aux to RCA

Ok, this is the last option available. If you don’t have other options available or you don’t like others. For this, you will need the RCA cable. Which one end is AUX and the other is RCA. It will be the analog audio connection. The connection process will be like this.

  1. Turn off your both devices.
  2. At the soundbar, you have to find the aux cable port. While in the projector you have to find the RCA port. Which will be in white and red color.
  3. When you get both ports. On your projector and soundbar. You have to take your aux to RCA cable. 
  4. And connect the aux cable in the soundbar. And the RCA side of the cable will go in the projector.

This will be perfect for the 2.1 channel soundbar. And also if your soundbar is 3.1 channel. It will degrade your 3.1 to 2.1 channel. So it will be better if you use the low-end soundbar (2.1 channel) with the aux to RCA connection.
