HDMI (High-Definition Multimedia Interface) ARC (Audio Return Channel) is a feature that allows audio to be sent from your TV to your soundbar or home theatre system using a single HDMI cable.
It simplifies your home theatre setup by reducing cable clutter and allowing two-way communication between devices. However, some users may wonder whether they can use HDMI ARC as a regular HDMI cable.
This article will explore the answer to this question and provide helpful information about using HDMI ARC and its capabilities.
Can I Use HDMI ARC as Regular HDMI?
Yes, you can use HDMI ARC (Audio Return Channel) as a regular HDMI cable, but it may not provide the same level of audio quality as using HDMI ARC for audio. HDMI ARC allows two-way communication between devices, transmitting audio from your TV to your soundbar while receiving commands from your TV’s remote control.
However, if you use HDMI ARC as a regular HDMI cable, it will only transmit audio from your device to your TV or from your TV to your device, depending on which end you plug it into. It cannot transfer audio from your TV to your soundbar.
Additionally, using HDMI ARC for audio can provide certain benefits, such as support for high-quality audio formats like Dolby Atmos and DTS: X. If your soundbar supports these formats and you want to take advantage of them, you must use HDMI ARC for audio.
In summary, while you can use HDMI ARC as a regular HDMI cable, it may provide a different audio quality and functionality than using HDMI ARC for audio.
HDMI VS HDMI ARC Comparison
HDMI (High-Definition Multimedia Interface) and HDMI ARC (Audio Return Channel) are both HDMI cables that transmit audio and video signals between devices. However, some key differences between HDMI and ARC are worth considering when setting up your home theatre system.
HDMI cables transmit high-definition video and audio signals from a source device, such as a Blu-ray player or gaming console, to a display device, such as a TV or projector. HDMI cables can transmit audio and video signals and support a wide range of resolutions, from standard definition to 4K Ultra HD.
HDMI ARC, on the other hand, is a feature that allows audio to be sent from a TV to a soundbar or home theatre system using a single HDMI cable. It simplifies your home theatre setup by reducing cable clutter and allows for two-way communication between devices. HDMI ARC can transmit high-quality audio formats, such as Dolby Atmos and DTS:X, providing an immersive audio experience.
One key difference between HDMI and HDMI ARC is that HDMI ARC only supports audio transmission, while regular HDMI cables can transmit audio and video signals. Additionally, not all devices support HDMI ARC, so you will need to check the specifications of your TV and soundbar to ensure they support HDMI ARC before using it.
In summary, both HDMI and HDMI ARC are essential components of a home theatre setup and are used to transmit audio and video signals between devices. While HDMI cables are used for general audio and video transmission, HDMI ARC is a specialized feature that simplifies your home theatre setup and allows for high-quality audio transmission.
HDMI ARC VS HDMI eARC
HDMI ARC (Audio Return Channel) and HDMI eARC (enhanced Audio Return Channel) are both HDMI cables that allow for audio transmission between devices in a home theatre setup. However, some differences between HDMI ARC and HDMI eARC are worth considering when setting up your system.
HDMI ARC:
HDMI ARC is a feature that allows audio to be sent from a TV to a soundbar or home theatre system using a single HDMI cable. HDMI ARC supports up to 5.1-channel audio and can transmit high-quality audio formats such as Dolby Atmos and DTS: X. However, HDMI ARC has limited bandwidth and may not support all audio formats.
HDMI eARC
HDMI eARC is an enhanced version of HDMI ARC that provides improved audio quality and higher bandwidth. HDMI eARC supports up to 32 channels, including advanced audio formats such as Dolby Atmos and DTS: X. It also supports lip-sync correction and audio volume control features.
Differences
The main difference between HDMI ARC and HDMI eARC is the level of audio quality and bandwidth they provide. HDMI eARC offers higher audio quality and higher bandwidth than HDMI ARC. This makes it better suited for advanced audio formats and larger home theatre setups.
Compatibility
Not all devices support HDMI eARC, and it is essential to check the specifications of your TV and soundbar to ensure they support HDMI eARC before using it. HDMI eARC is backwards compatible with HDMI ARC, meaning it will work with only supporting devices.
HDMI ARC and HDMI eARC are important features for transmitting audio between devices in a home theatre setup. HDMI eARC provides improved audio quality and higher bandwidth than HDMI ARC, making it better suited for advanced audio formats and larger home theatre setups. However, not all devices support HDMI eARC, and it is essential to check the specifications of your devices before using them.
Frequently Asked Questions (FAQs)
Do I need a special HDMI cable for the ARC?
No, you don’t need any special HDMI cable for an arc. You can use the regular cable you have. If you want access to the soundbar’s advanced features, you need to go for the ultra-high-speed HDMI cable.

Yes, the HDMI arc is better than the optical cable because HDMI supports all the advanced features optical cable doesn’t support.
Can HDMI ARC be used as HDMI input?
No, HDMI ARC cannot be used as an HDMI input. HDMI ARC is a specialized feature that allows audio to be sent from a TV to a soundbar or home theater system using a single HDMI cable. It only supports audio transmission and cannot be used for general audio and video transmission like an HDMI input.
Can eARC be used as regular HDMI?
Yes, eARC (enhanced Audio Return Channel) can be used as a regular HDMI cable for general audio and video transmission. eARC is an enhanced version of HDMI ARC that provides improved audio quality and higher bandwidth. It is backward compatible with HDMI ARC and regular HDMI, which means that it can be used as a regular HDMI cable for general audio and video transmission, in addition to its enhanced audio capabilities.
Conclusion
HDMI ARC (Audio Return Channel) is a specialized feature that allows audio to be sent from a TV to a soundbar or home theatre system using a single HDMI cable.
While HDMI ARC can support high-quality audio formats such as Dolby Atmos and DTS:X, it cannot be used as a regular cable for general audio and video transmission.
Therefore, if you need to transmit both audio and video signals between devices, you will need to use regular HDMI cables in addition to HDMI ARC. It’s essential to check the specifications of your devices and choose the appropriate cables to ensure optimal performance when setting up your home theatre system.
