Can I use eARC without CEC?

Answered by Cody Janus

You can use eARC (enhanced Audio Return Channel) without CEC (Consumer Electronics Control) enabled. Let’s dive into the details.

First, let’s briefly understand what eARC and CEC are. eARC is an enhanced version of the ARC feature found in HDMI (High-Definition Multimedia Interface) connections. It allows for the transmission of higher-quality audio signals, such as Dolby Atmos and DTS:X, from your TV to an eARC compatible audio system. On the other hand, CEC is a feature that enables different devices connected via HDMI to control each other using a single remote.

While it is generally recommended to keep CEC enabled, as it allows you to control various devices connected over HDMI with a single remote, there are instances where it can cause issues. These issues may include unintended device control, power on/off problems, or input switching conflicts. In such cases, disabling CEC might be a solution.

However, disabling CEC does not necessarily mean you cannot use eARC. eARC operates independently of CEC, and you can still benefit from the enhanced audio capabilities it provides. eARC allows for the transmission of high-quality audio formats, such as lossless audio, from your TV to an eARC compatible audio receiver or soundbar. This is particularly useful if you have a setup that involves an audio system separate from your TV.

To disable CEC, you’ll need to access the settings on your TV. The process may vary depending on the brand and model of your TV, but generally, you can find the CEC settings under the “System” or “Settings” menu. Look for options like “HDMI-CEC,” “CEC Control,” or “Device Control,” and disable it. Once disabled, your TV should no longer send or receive CEC commands.

It’s important to note that by disabling CEC, you won’t be able to send device commands, such as volume control or power on/off, over HDMI. However, if you primarily use a separate remote or a universal remote to control your devices, this may not be a significant concern. Additionally, other methods, such as IR (infrared) or RF (radio frequency) remotes, can still be used to control individual devices.

While it’s generally recommended to keep CEC enabled for convenient device control, if you’re experiencing headaches or conflicts with CEC, it is possible to use eARC without CEC. Disabling CEC will not affect the functionality of eARC, allowing you to enjoy high-quality audio from your TV to an eARC compatible audio system.
