When it comes to connecting devices to our TVs, projectors, or soundbars, HDMI cables have become the standard solution. With the ability to transmit high-definition video and audio signals over a single cable, HDMI has made it easy to enjoy a seamless entertainment experience. However, as we dive deeper into the world of HDMI, a question arises: do all HDMI cables support audio return channel? In this article, we’ll explore the answer to this question and uncover the hidden truth about HDMI cables.
What is Audio Return Channel (ARC)?
Before we dive into the world of HDMI cables, it’s essential to understand what Audio Return Channel (ARC) is. ARC is a feature that allows audio signals to be sent from a TV to an external audio device, such as a soundbar or home theater system, over an HDMI connection. This feature eliminates the need for a separate audio cable, making it easy to enjoy a more immersive audio experience.
ARC was first introduced in HDMI 1.4, and it has since become a standard feature in many HDMI devices. However, not all HDMI cables support ARC, which is where the confusion begins.
The Different Types of HDMI Cables
When it comes to HDMI cables, there are several types to choose from, each with its own set of features and capabilities. Here are some of the most common types of HDMI cables:
HDMI Version 1.0-1.3
The earliest versions of HDMI cables, ranging from version 1.0 to 1.3, were limited in their capabilities. These cables could only transmit video signals and did not support audio return channel.
HDMI Version 1.4
With the introduction of HDMI 1.4, the landscape changed. This version of HDMI introduced ARC, making it possible for audio signals to be sent from a TV to an external audio device over an HDMI connection. HDMI 1.4 cables are capable of transmitting video signals at a resolution of up to 4K at 30Hz.

What is Audio Return Channel (ARC) and how does it work?
Audio Return Channel (ARC) is a feature that allows a TV to send audio signals back to an A/V receiver or soundbar through an HDMI cable. This eliminates the need for a separate audio cable, making it a convenient feature for home entertainment systems. ARC works by allowing the TV to send audio signals to the A/V receiver or soundbar, which then processes and amplifies the audio, producing a better sound quality.
The ARC feature is especially useful for streaming devices like Roku, Amazon Fire TV, and Google Chromecast, which are connected to the TV and produce audio signals. Without ARC, you would need a separate optical audio cable to connect the streaming device to the A/V receiver or soundbar. With ARC, the audio signals are sent through the HDMI cable, simplifying the setup and reducing clutter.
Do all HDMI cables support Audio Return Channel (ARC)?
No, not all HDMI cables support Audio Return Channel (ARC). ARC is a feature that requires specific hardware and software support, and not all HDMI cables are designed to support it. In fact, ARC is only supported on HDMI version 1.4 and later, which means that older HDMI cables may not support ARC.
If you’re looking for an HDMI cable that supports ARC, make sure to check the specifications of the cable before making a purchase. Look for cables that specifically mention ARC support or are labeled as “HDMI 1.4” or later. Additionally, some cables may support eARC (enhanced Audio Return Channel), which is a newer version of ARC that offers even better audio quality.
What is the difference between ARC and eARC?
ARC (Audio Return Channel) and eARC (enhanced Audio Return Channel) are both features that allow a TV to send audio signals to an A/V receiver or soundbar through an HDMI cable. However, eARC is a newer and improved version of ARC that offers several advantages. eARC supports higher quality audio, including 3D audio formats like Dolby Atmos and DTS:X, whereas ARC only supports up to 5.1 surround sound.
eARC also offers lower latency and improved lip sync, which means that the audio and video are more closely synchronized, resulting in a better viewing experience. Additionally, eARC can support up to 32 channels of audio, whereas ARC is limited to 5.1 channels. If you’re looking for the best possible audio quality, eARC is the way to go.
Do I need a special HDMI cable for eARC?
Yes, eARC requires a special type of HDMI cable that is capable of supporting the higher bandwidth and faster data transfer rates required for eARC. eARC cables are typically labeled as “HDMI 2.1” cables, which indicate that they support the latest HDMI standard.
Not all HDMI cables are created equal, and eARC cables are designed to meet the specific requirements of eARC. Look for cables that are specifically labeled as eARC-compatible or HDMI 2.1 cables, and make sure they are certified by organizations like the HDMI Organization.
Can I use an ARC cable for eARC?
No, ARC cables are not compatible with eARC. While both ARC and eARC allow a TV to send audio signals to an A/V receiver or soundbar, they have different technical requirements and are not interchangeable.
ARC cables are designed to support up to 5.1 surround sound, whereas eARC cables are capable of supporting up to 32 channels of audio. Using an ARC cable for eARC would result in reduced audio quality and potential compatibility issues. If you want to take advantage of eARC, make sure to use a cable that is specifically designed for eARC.
What devices support eARC?
eARC is supported by a growing number of devices, including TVs, soundbars, and A/V receivers from various manufacturers. Some of the popular brands that support eARC include Samsung, LG, Sony, and Denon.
