Best HDMI to Optical Cable Adapters for TV Audio Output in 2026
Answer: If your TV only offers HDMI ARC/eARC and you want to send high-quality audio to a soundbar, amplifier, or home theater, an HDMI ARC/eARC to optical (Toslink) adapter is an essential upgrade. This guide highlights five reliable options and who benefits most from each. It covers common caveats like CEC setup, PCM requirements, and whether eARC is supported. The selected products are best for different user needs, from simple plug-and-play setups to more feature-rich extractors with CEC control.
| Product | Best For | Why It Stands Out |
|---|---|---|
| YEUGICEO 192KHz HDMI eARC/ARC to Optical Coaxial Audio Converter | General TV audio upgrades | Supports 24-bit/192kHz, PCM, ARC to optical/coaxial output, CEC volume control |
| 192KHz HDMI ARC to Optical Audio Adapter 6.6FT (ESWN DNXB) | Simple ARC to optical needs | Plug & Play, high sampling rate, works with USB power |
| HDMI ARC to Optical Audio Converter (Tackston) | ARC to Toslink without eARC | Not for eARC, straightforward setup, PCM/Dolby/DTS compatible |
| 192KHz HDMI ARC to Optical Audio Adapter (IHTHER) | Home theater with linked devices | Supports PCM/LPCM/Dolby 5.1/DTS 5.1, 24-bit/192kHz |
| YEUGICEO 192KHz HDMI eARC/ARC to Optical Coaxial Audio Converter with CEC | High-end ARC/eARC setups | PCM2.0, Dolby 5.1, DTS 5.1, CEC volume control |
YEUGICEO 192KHz HDMI eARC/ARC to Optical Coaxial Audio Converter
This ARC/eARC extractor converts the TV’s ARC audio to digital optical or coaxial output, enabling seamless connection to soundbars or receivers. Best for buyers who need compatibility with older or separate digital audio gear. It supports 24-bit/192kHz PCM and includes CEC volume control for convenient use with a connected TV. Use this if your TV requires a CEC-enabled setup and you want to control volume from the TV remote. A potential limitation is dependence on ARC compatibility and proper PCM settings on the TV.
192KHz HDMI ARC to Optical Audio Adapter 6.6FT (ESWN DNXB)
This plug-and-play ARC to optical adapter is best for users who want a simple, no-frills solution. It supports up to 24bit/192kHz sampling and works with a USB power supply. It’s ideal for TV-to-soundbar setups where you don’t need advanced CEC features. Caution: Not designed for HDMI eARC; verify your TV’s ARC labeling to ensure compatibility.
HDMI ARC to Optical Audio Converter (Tackston)
Best for TVs with ARC but not eARC, this adapter provides a reliable way to move audio from HDMI ARC to Toslink. It supports PCM and Dolby/DTS formats, with a clear note that the TV’s ARC function must be used and volume control may require the playback device. A minor caveat is that it requires the TV to set digital output to PCM for optimal performance.
192KHz HDMI ARC to Optical Audio Adapter (IHTHER)
Designed to deliver theater-like sound, this adapter converts HDMI ARC to optical while supporting PCM, LPCM, Dolby 5.1, and DTS 5.1. It’s best for users who want flexible audio formats and a straightforward plug-and-play setup. Limitations include the need for ARC-compatible TVs and compatible sound systems to enjoy surround formats fully.
YEUGICEO 192KHz HDMI eARC/ARC to Optical Coaxial Audio Converter with CEC
This high-end option covers eARC and ARC with an integrated CEC volume control. It supports PCM 2.0, Dolby 5.1, and DTS 5.1, and includes a shorter 5 ft cable for convenient TV-to-soundbar distances. Choose this if you need robust compatibility with eARC-equipped TVs and want direct control from the TV remote. A potential caveat is configuring CEC and ensuring the TV outputs PCM or compatible formats.
Buying Guide: Key Purchase Considerations
- ARC vs. eARC: Confirm your TV port type. eARC offers higher bandwidth for object-based audio but may require a compatible sound system.
- Audio Formats: Look for support of PCM, LPCM, Dolby Digital, and DTS. If your setup uses Dolby/DTS, ensure the adapter can pass those formats without downmixing.
- CE C and Volume Control: If you want TV-based volume control, choose models with CEC compatibility or explicit volume control features.
- Power Requirements: Many adapters need USB power. Check if your TV’s USB port can supply power or if an external power adapter is included.
- Distance and Cabling: Consider cable length (3–6.6 feet in this list) and how it fits your room layout without excess cable slack.
- Ease of Setup: Plug-and-play options reduce setup time, while more feature-rich units may require more configuration (PCM settings, CEC, and TV audio output adjustments).
