A Guide To Using Home Theater Speakers With A Computer

Computers are much more powerful now than they were a few years ago. People may now use them to mix and match audio recordings, put on a DJ event, and even play high-definition home theater audio. However, figuring out how to do this isn’t always simple. Older home theater systems are a bit more difficult, requiring you to handle more wiring and connections.

Newer installations even come without receivers, instead of connecting audio through a single HDMI receiver. Regardless of your setup, this article will explain how to utilize home theater speakers with a computer and provide some more information if you don’t already have one.

Connecting Cables

Step 1: Make sure you have three 3. mm to RCA cables on hand.

For your 5.1 speaker system, you’ll need three of these! The 3.5mm imports in which that end connects to your computer will be on your computer. These cables are compatible with both your speaker system and computer, regardless of the sound card you have installed on your PC. The primary speaker with all the connecting cables must be within a few feet of your computer. Connect through Bluetooth or a regular aux wire if you’re using a soundbar. Receivers will also feature the necessary import jacks. You can see how to link each of the cables to the PC and home theater system in the clip below.

Step 2: Connect the cables to the appropriate jack ports.

This is a simple step that will likely be the most significant in the end. Colored audio ports, such as blue, green, and pink/red, are available on computers. Our cords are identical to the ones in the video, and yours should be as well.

  • Connect the Blue port to your home theater receiver’s SR (surround right) and SL (surround left) inputs.
  • Connect the Green port to your home theater receiver’s FR (front right) and FL (front left) inputs.
  • Connect your PC’s Pink port to your home theater receiver’s C (center) and SW (subwoofer) sections.
  • If you don’t have a subwoofer or one of the above-mentioned speaker sets, skip those procedures. In the future, you can always add more speaker systems to make a full 5.1 system.


You’ll need to download or use an Audio Manager program on your computer if you’re using a typical 5.1 audio system.

Realtek HD Audio Manager in Windows 10 is the ideal program for managing all sound output and settings. The current version of this program should already be installed on newer computers, but here’s how to make sure you have the most up-to-date and proper version for speaker calibration.

Check the quality of your audio output

You’re good to go if your speakers quickly calibrate and emit the right audio for each one. If not, you’ll need to do some fast and simple audio calibration to finish your set.

  • See whether you can “configure speakers” by default in your audio device settings.
  • Pair the three audio port settings from the cords you just plugged in using your Realtek HD Audio program.
  • If you’re experiencing problems, you may want to try the following:

Uninstall the current version of Realtek HD Audio.

Step 1: Device Manager –> Sound Video and Game Controllers –> Realtek High Definition Audio –> uninstall, delete the driver software for this device.

Step 2: Go to Device Manager and choose View. Display all hidden gadgets (delete and uninstall any audio that has Realtek HD in case you missed it).

Step 3: Get drivers that are compatible with your speakers. To save you a lot of time and effort. If you need assistance with this step, We suggest phoning Best Buy. They’ve always been helpful with our home theater setup, and they provide free consultations as well. If you’re experiencing problems with this stage due to your specific configuration, they can provide one-on-one assistance so you don’t have to worry.

How to Connect a Soundbar to a Computer

You may connect it to your computer in a few different ways. The simplest method is to use Bluetooth to connect to the Soundbar. These speaker systems are quite responsive, and assuming your computer has a proper Bluetooth connection, latency should not be a problem.

You may also plug a two-way 3.5mm connection and switch the soundbar’s settings to Audio Out to listen to music. Because the soundbar will operate as an external speaker to your computer rather than your projector or PC, you’ll have to plan on playing media from your computer.

Playing Audio With HDMI Connections

Yes, this is completely feasible! If you wish to transmit audio to your speaker, you must change the settings on your computer.

Go to Control Panel –> Sound –> Playback tab –> HDMI setting.

Note: If you don’t have access to an HDMI cable, it could be better to simply use an Aux connection to save time. There was a time when we were moving our home theater speakers around when we connected the laptop video via HDMI and then an Aux connection to our speakers. The necessity for cable signal setup was eliminated by doing it in this manner.

Connecting a Laptop To Surround Sound Systems- HDMI and VGA

To begin, you’ll need two HDMI cords.

One connects to your laptop, while the other connects to your home theater receiver’s (PC) port. The second HDMI cable connects to your receiver’s main port and the video port on your TV or projector.

You may also use VGA and a (1) 3.5mm RCA cable to connect your laptop to a surround sound speaker system.

Make sure your laptop’s VGA connector and your screen’s VGA connection are both females.

1. Connect the VGA cable to both the laptop and the monitor.

2. Connect the 3.5mm end into the laptop’s headphone jack.

3. Connect the receiver’s RCA end (labeled “PC”) into the RCA end of the cable. The white should be plugged into the white, and the red should be plugged into the red. If your TV or projector is not set to PC input, the sound will not operate.


As you can see, there are several options for setting up your home theater audio system. Some alternatives need a little more fiddling with the setup settings, but that doesn’t rule them out. We just phoned Best Buy assistance if we thought our setup was too unusual to get answers on the internet, and they were always able to assist us with anything we needed.

If you’ve never calibrated 5.1 speaker systems with a PC before, it may be a little tough, but once you’re acquainted with your computer’s software and speaker hardware, you’ll always know what you need to do to get them up and running.
