Trying to connect a newer TV to a soundbar that only has an optical input? An HDMI eARC or ARC audio adapter can bridge that gap, but the labels alone do not tell you whether it will work with your TV, audio format, and remote.
These 10 options cover straightforward eARC-to-optical converters as well as extractors with additional connections. Start with the ports on your equipment, then check the formats and features you actually need.

How We Picked the Best Hdmi Earc Audio Adapters for Soundbars
We focused on the connection problem each adapter is intended to solve: getting audio from a TV’s HDMI eARC or ARC port to a soundbar or other audio device. We compared the stated inputs and outputs, eARC versus ARC labeling, listed audio formats, power requirements, and practical details such as attached cables. Product names are not a substitute for a full specification sheet, so verify the current listing before buying—especially if a feature is essential to your setup.
Quick Comparison: Match the Output to Your Soundbar
Most Hdmi Earc Audio Adapters for Soundbars in this roundup are aimed at sending TV audio to an optical input. That makes them most relevant if your TV has HDMI eARC/ARC but your soundbar lacks a compatible HDMI connection. The HDMI ARC extractors in the selection also mention options such as 3.5 mm audio or video-related specifications; check their port diagrams carefully rather than assuming they work like the simpler eARC-to-optical models.
If your soundbar already has an HDMI eARC or ARC port, first try a direct HDMI connection. An adapter adds another device, cable, and power requirement without necessarily improving the audio.
Key Buying Factors for Hdmi Earc Audio Adapters for Soundbars
Signal Direction and Port Compatibility
Confirm that the adapter accepts audio from your TV’s HDMI eARC/ARC port and outputs through the connection your soundbar accepts. “HDMI to optical” can also describe devices designed for a streaming box or game console, which may not extract audio from a TV’s return channel. Check whether the listing explicitly supports eARC, ARC, or both.
Audio Formats and TV Settings
Optical output is commonly used for stereo PCM and supported compressed surround formats such as Dolby Digital 5.1 or DTS 5.1. Do not assume an optical adapter will carry lossless eARC formats, Dolby Atmos, or every format available through your TV. Match the adapter’s stated support to your soundbar, then set the TV’s digital audio output to a compatible format if you hear silence or get only stereo.
Power, Cables, and Remote Control
Check whether USB power is required, whether a power supply is included, and whether an HDMI cable is attached or must be purchased separately. CEC support matters if you expect the TV remote to control volume or power: some listed adapters explicitly say they do not support CEC. Optical connections also do not inherently provide HDMI-style volume control, so plan for the soundbar’s remote or another supported control method.
Video Specifications
Some extractors advertise 4K resolution or refresh-rate figures. Those specifications matter only if video passes through the device. For a TV eARC/ARC-to-optical connection, prioritize return-audio compatibility over a 4K label.
Who Should Buy Which Hdmi Earc Audio Adapters for Soundbars?
Choose a basic eARC/ARC-to-optical converter if your goal is simply to connect a TV to an optical-only soundbar. Prioritize clearly stated Dolby Digital or DTS support if you want compatible 5.1-channel audio rather than stereo PCM. Consider a model with extra analog outputs only if another speaker system needs them, and check its input and output direction first. If you depend on one-remote volume control or lossless surround audio, a direct eARC connection—or different audio equipment—may be a better fit than an optical adapter.
