To connect a soundbar to a TV with HDMI, you’ll need an HDMI cable. Identify the HDMI ARC or eARC port on your TV and soundbar, connect them, set your TV’s audio output to HDMI ARC, and select the correct input on your soundbar. This provides superior audio quality and simplifies control.
Upgrading your TV’s audio with a soundbar can transform your viewing experience, making movies and music sound richer and more immersive. HDMI is the preferred connection method because it can carry high-quality audio signals, including surround sound formats like Dolby Atmos, and often allows you to control both devices with a single remote.
This guide will walk you through the entire process, from checking your TV’s ports to configuring the settings, ensuring you get the best possible sound from your setup.
What You’ll Need
- A soundbar with an HDMI input (preferably labeled HDMI ARC or eARC).
- A television with an HDMI port (preferably labeled HDMI ARC or eARC).
- One or two high-speed HDMI cables (often included with the soundbar).
- The remote controls for both your TV and soundbar.
- Your TV and soundbar user manuals for specific model instructions (recommended).
How to Connect Your Soundbar to TV with HDMI, Step by Step
Step 1: Identify the Correct HDMI Ports
First, locate the HDMI ports on the back or side of your TV and soundbar. Look for a port labeled “HDMI ARC” (Audio Return Channel) or “HDMI eARC” (enhanced Audio Return Channel). The ARC feature allows audio to travel both to and from the TV over a single HDMI cable, which is crucial for sending sound from your TV’s apps or connected devices back to the soundbar. If your devices lack ARC labels, any HDMI port will work for basic audio output, but you may need a separate optical cable for audio from TV apps.
Step 2: Connect the HDMI Cable
Take your high-speed HDMI cable and plug one end into the HDMI ARC port on your TV. Plug the other end into the HDMI OUT (ARC) port on your soundbar. Ensure both your TV and soundbar are powered off or unplugged during connection to avoid any potential electrical issues. If your soundbar has multiple HDMI inputs and an output, make sure you are using the designated HDMI OUT or ARC port.
Step 3: Power On and Select Inputs
Turn on your TV and soundbar. Using your soundbar’s remote or controls, select the HDMI ARC input. This might be labeled “TV,” “ARC,” or “HDMI.” On your TV, you may need to navigate to the input/source menu and select the HDMI port to which the soundbar is connected to see a visual confirmation, though audio will be the primary output.
Step 4: Configure Your TV’s Audio Settings
This is the most critical step. Go into your TV’s settings menu, often found under “Sound,” “Audio,” or “Settings.” Look for “Audio Output” or “Speaker Settings.” Change the option from “TV Speakers” to “External Speakers” or “Audio System.” Then, find the setting for “Digital Audio Out” or “HDMI Audio” and set it to “Auto,” “PCM,” or “Bitstream.” “Auto” is usually the best choice as it lets the TV automatically send the correct signal. Finally, ensure the “HDMI ARC” or “eARC” function is turned ON if there is a separate toggle.
Step 5: Test the Audio
Play content from a TV app like YouTube or a connected device like a streaming stick. You should hear the audio coming from the soundbar, not the TV’s built-in speakers. Adjust the volume using your soundbar remote. If you have a universal remote or your TV remote supports HDMI-CEC (often called SimpLink, Anynet+, or BRAVIA Sync), you might be able to control the soundbar’s volume with your TV remote.
Step 6: Connect Additional Devices (Optional)
For the best audio from gaming consoles, Blu-ray players, or set-top boxes, connect them directly to the HDMI IN ports on your soundbar, if available. Then, use the soundbar’s HDMI OUT (ARC) to connect to the TV. This allows the soundbar to process the high-quality audio signal directly before passing the video to the TV.
Recommended Products
While this guide focuses on the connection process, having the right equipment makes a difference. For a complete home theater experience, a quality projector or monitor can pair well with your new audio setup. For instance, connecting a powerful projector like the JVC DLA-NZ900 D-ILA Projector via HDMI ensures both stunning visuals and audio are handled through a single cable when paired with a compatible soundbar. Similarly, a clear monitor like the LG 24G411A-B 24-inch Ultragear Full HD is great for desktop setups where you might connect a soundbar for enhanced PC audio.

Common Mistakes to Avoid
- Using the Wrong HDMI Port: Not using the ARC-labeled ports prevents audio from returning from the TV to the soundbar for built-in apps.
- Forgetting to Change TV Audio Output: Leaving the TV set to “TV Speakers” means no sound will come from the soundbar.
- Using a Low-Quality HDMI Cable: Older cables may not support ARC or the bandwidth needed for high-definition audio formats.
- Not Enabling CEC/ARC in TV Settings: These features are often not enabled by default and must be manually turned on.
- Assuming Instant Sound: Some TVs require a reboot or need you to cycle power on the soundbar after connection for the handshake to complete.
- Ignoring Manufacturer Manuals: Specific brands like Samsung, LG, or Sony may have slightly different menu labels for audio settings.
Frequently Asked Questions
Whatu0026#039;s the difference between HDMI ARC and regular HDMI?
HDMI ARC (Audio Return Channel) is a feature on specific HDMI ports that allows audio to travel in both directions over a single cable. A regular HDMI port only sends audio and video *to* the TV. With ARC, audio from your TV’s tuner or apps can be sent *back* to your soundbar, eliminating the need for a separate optical audio cable.
My TV doesnu0026#039;t have an HDMI ARC port. Can I still use HDMI?
Yes, you can connect any HDMI output on your soundbar to any HDMI input on your TV. However, you will only get sound from devices connected directly to the soundbar’s HDMI inputs. To get sound from your TV’s internal apps, you would need to use a separate connection, like an optical audio cable.

Why is there no sound after Iu0026#039;ve connected everything?
First, double-check that your TV’s audio output is set to u0022External Speakersu0022 or u0022Audio Systemu0022 and not u0022TV Speakers.u0022 Second, ensure the soundbar is set to the correct HDMI input. Third, try unplugging both devices from power for 60 seconds to reset the HDMI handshake. Finally, consult your TV’s manual for specific audio settings, as the exact menu names vary.
Should I use PCM or Bitstream audio format?
Set your TV’s digital audio output to u0022Autou0022 if available. This lets the TV decide. If you must choose, select u0022Bitstreamu0022 to send compressed surround sound formats (like Dolby Digital) to your soundbar for decoding. Choose u0022PCMu0022 if you are only getting stereo sound or if you experience audio dropouts with Bitstream.
Can I connect multiple devices through my soundbar?
Yes, if your soundbar has multiple HDMI inputs, you can connect devices like a game console, Blu-ray player, or streaming stick directly to it. Connect the soundbar’s HDMI OUT to your TV’s HDMI ARC port. This routes all audio through the soundbar and sends video to the TV, often providing the highest quality audio experience for those devices.
Final Thoughts
Connecting a soundbar to your TV with HDMI is a straightforward process that yields a significant upgrade in audio quality and system simplicity. The key is carefully following each step: identifying the right ports, changing the essential TV settings, and testing the setup. Remember that HDMI ARC is a powerful feature that streamlines your entire entertainment system, allowing for single-cable convenience and high-fidelity sound from all your content sources.
If you run into issues, methodically retrace these steps and consult your device manuals. With a correct setup, you’ll enjoy immersive audio that perfectly complements your viewing, whether you’re watching a blockbuster movie or streaming your favorite show.
