Got a new soundbar? If you’ve tried plugging it in and connecting it to your TV with an HDMI cable, yet nothing happens, it’s probably not the right one. You won’t hear any sound at all; it’s what many users have experienced mostly because they’re using the wrong HDMI port. So, if you try to use a different HDMI port and it suddenly works, you will have your answer right there. 

Most of the time, the issue is never the cable itself or your soundbar. The issue is mostly that you probably didn’t use the right HDMI port. 

Not all HDMI ports are the same, and one works better for audio compared to another kind, which in this case is the HDMI ARC port.

What is HDMI ARC?

HDMI ARC (Audio Return Channel) is a feature built into specific HDMI ports. It allows audio to travel in both directions through a single cable, rather than just one way.

Usually, an HDMI cable transmits audio and video from your source device, for instance, a game console or Blu-ray player, to your TV. 

The audio then plays through your TV’s internal speakers or is routed via a separate optical cable to your soundbar. So, that’s two cables, two connections, and twice the effort.

However, here’s where an HDMI ARC changes the game. With it, your TV can send audio back down the same HDMI cable to an external speaker system. This means you can reduce cable clutter and make your entire setup much simpler.

What is HDMI ARC Used For?

In the simplest terms, HDMI ARC is used to send audio from your TV to external speakers or a soundbar. This eliminates the need for a separate optical audio cable. 

Here are some use cases where an HDMI ARC does well: 

• Better TV audio: Built-in TV speakers are often thin and lack bass. An ARC lets you connect a soundbar for a much better experience.
• Multiple device usage: If you have a game console, a Blu-ray player, and a streaming stick all plugged into your TV, they all output audio through the TV. With HDMI ARC, your soundbar will play audio from all of these sources. It’s all automatic with no cable swapping required.
• You want one remote control: ARC works with a system called HDMI-CEC (Consumer Electronics Control). This lets you use your TV remote to adjust the volume on your soundbar.

TIP – When ARC is enabled, your TV might automatically disable its internal speakers, and the audio output will switch to your soundbar or receiver.

HDMI ARC vs.HDMI

Many users ask about the difference between a regular HDMI cable and an HDMI ARC. Check the reference table below to get a clearer idea of it: 

What Does an HDMI ARC Port Look Like?

It looks exactly like any other HDMI port. However, the only difference is the label. If you take a look on the back or side of your TV for an HDMI port, it’s marked as “ARC” or “eARC/ARC.”  

Some TV brands also have specific ports designated for ARC. For example, Samsung’s third HDMI port on their One Connect Box has it.

Is HDMI eARC the Same as HDMI ARC?

No, they’re not the same.

If you’ve been looking for the latest TV or soundbar, you’ve likely seen eARC mentioned. eARC stands for Enhanced Audio Return Channel and is the superior version of the standard ARC.

The core difference? The HDMI eARC is an HDMI 2.1 feature that offers significantly higher bandwidth. It allows the transmission of superior, higher-quality audio formats.

ARC vs. eARC – Key Comparisons

Here are the main differences between the two:

When Would the HDMI eARC Matter?

If you’ve got an HDMI ARC, it’s well and good.

However, if you’re looking to enjoy truly immersive audio formats like Dolby Atmos with object-based sound that moves around you, you need eARC.

The standard ARC does not have the bandwidth to carry these high-bit rate, uncompressed audio tracks.

So, for those who’re mainly looking to create a premium home theater experience with the best possible sound from your movies, music, and games, eARC is the way to go.

Other than that, the ARC is perfectly fine. 

Can I Use HDMI ARC as Regular HDMI?

Yes, you can. An HDMI ARC port will function exactly like a standard HDMI input for video. 

You can plug any device, like a gaming console, Blu-ray player, or streaming stick, into an ARC port, and you’ll still get picture and sound on your TV.

However, there’s a catch. If you connect a soundbar or receiver to a standard (non-ARC) HDMI port, you will not get audio from the TV through that soundbar.

The audio will have to travel the other way through the “return channel,” which doesn’t exist on a standard port.

It’s also important that you note that only one HDMI port on your TV is typically ARC-enabled. 

With that said, never plug an ordinary device into it if you also want to use a soundbar. That particular HDMI ARC port is your dedicated audio output channel.

How to Connect HDMI ARC to TV (Step-by-Step for Beginners)

Setting up HDMI ARC on your TV is straightforward, but it does require attention to detail. However, if you’re completely new to it, here’s a foolproof guide:

Step 1 – Identify the ARC Port

Check the back of your TV or go through the user manual to find the HDMI port. It’ll be labeled as ARC or eARC/ARC. This is your designated audio return channel.

Step 2 – Connect the HDMI Cable

Using a high-speed HDMI cable, plug one end into your TV’s HDMI IN (ARC) port. Plug the other end into the HDMI OUT (TV-ARC) port on your soundbar or receiver.

Step 3 – Turn Everything On

Turn your TV and your soundbar/AV receiver on. Your soundbar should automatically recognize the ARC connection. You may see “TV ARC” or “TV eARC” appear on its display.

Step 4 – Enable ARC in Your TV Settings (IMPORTANT!)

This is a very crucial step that most people often miss. Many TVs require you to enable ARC in the settings menu. The exact menu path will vary by brand, but generally, it follows these steps:

• Go to “Settings” > “Sound” > “Audio Output” > “Speakers.”
• Select “Audio System” or “Receiver” (HDMI).

Step 5 – Enable HDMI-CEC

ARC is often tied to the HDMI-CEC feature, which lets you control volume and power with a single remote. 

Manufacturers have different names for it; you can find them in the chart below captioned “Common TV Brand Names for HDMI-CEC”.

Step 6 – Test It

Lastly, you need to test it. Play something on your TV. If you hear audio from your soundbar, you’re set.

Can I Use HDMI for Gaming?

You absolutely can. HDMI is the standard for connecting gaming consoles to your TV for the best possible picture quality.

How to Connect Consoles to HDMI ARC

Here’s how:

1. Connect your console: Plug your PlayStation or Xbox into any HDMI port on your TV using a high-quality HDMI cable. For high-end gaming, ensure you’re using at least a Premium High-Speed HDMI cable, preferably an Ultra High-Speed HDMI cable if you’re using an HDMI 2.1 console.
2. Set the correct HDMI format: Many modern TVs require you to adjust a setting for HDMI signal format to get the best performance from your console. Look in your TV’s settings for “HDMI signal format” or similar and select the format that matches your console’s capabilities .
3. Enable VRR (Variable Refresh Rate): If you’re using a console and TV that support HDMI 2.1, enable VRR in your TV’s settings. This eliminates screen tearing and stuttering during gameplay.
4. The connection to HDMI ARC: Once your console is connected to your TV, the ARC connection will ensure that all game audio from your console is output through your soundbar. 

So, as long as you’ve set up ARC correctly, your soundbar will automatically play audio from your gaming console without any additional effort.

How to Use HDMI ARC with a Soundbar

Connecting your soundbar is the most common use case for HDMI ARC. Here’s the best way to go about it:

1. Locate the ARC/eARC ports: You’ll find them labeled on both your TV and your soundbar.
2. Connect the HDMI cable: Use a high-speed HDMI cable to connect the two.
3. Turn on ARC: Go into your TV’s audio output settings and select your soundbar as the speaker output. Also, turn on any related HDMI-CEC features on both devices. (Features include BRAVIA Sync or Anynet+) 
4. Troubleshoot: If you see “TV ARC” or “TV eARC” on the soundbar’s display, it means it’s working. If not, try power-cycling your devices.

Will HDMI ARC Work on Any TV?

No, it won’t. HDMI ARC will only work if both your TV and your audio device (soundbar or AVR) support ARC.

Here’s how to check if your TV supports ARC:

• Look for the label: Check the back or side of your TV for an HDMI port labeled “ARC” or “eARC/ARC.” 
• Check your manual: Your TV’s manual will specify if it supports ARC.
• Look at the specs: Look for HDMI version 1.4 or newer.

What if Your TV Doesn’t Have ARC?

Just in case your TV doesn’t support HDMI ARC, here’s what to do:

• Use an optical cable.
• Consider an upgrade to a newer TV with ARC or eARC.

How to Identify an HDMI ARC Cable

A standard high-speed HDMI cable with Ethernet carries ARC signals; no dedicated “ARC cable” exists. 

For ARC, use “High Speed” or better. For eARC and Dolby Atmos, an “Ultra High Speed” (HDMI 2.1) cable is required. 

If your current cable works, it’s fine for ARC. Problems indicate poor quality, not missing ARC support.
