An HDMI ARC audio extractor that returns TV sound to amplifiers, soundbars and headphones using optical, RCA and 3.5 mm outputs. Home cinema owners gain a straightforward way to bridge modern TVs with older audio kit. Is SDKDZKG HDMI ARC Audio Extractor the simplest solution for TVs that lack dedicated audio outputs?
⚡ At a Glance
- • Audio Quality: Supports up to 192 KHz sampling, clear stereo and multichannel passthrough
- • Best for: Owners who need to route TV audio into soundbars, amplifiers or headphones
- • Not ideal for: Homes without an HDMI ARC-capable TV, or setups needing Bluetooth output
Supports HDMI ARC input with simultaneous audio outputs to optical, RCA and 3.5 mm. Sampling rates include 32, 44.1, 48, 96 and 192 KHz for higher-resolution playback.
Easy TV-to-stereo connection - with HDMI ARC passthrough
Connect the HDMI ARC port of the TV to the adapter, then switch the adapter ON and enable ARC in the TV settings. HDMI ARC returns the TV's audio signal so downstream audio gear receives the source audio over a single HDMI cable.
One-cable connection simplifies wiring for soundbars and AV amplifiers, eliminating the need for separate audio outputs. TV volume and basic controls can be handled through CEC when supported by HDMI cables and devices.
High-resolution audio support - with 192 KHz sampling
The DAC extractor accepts S/PDIF input bitstreams and supports sampling rates up to 192 KHz, plus 24-bit S/PDIF input bitstreams on left and right channels. Using a recommended AGW26 19+1 core HDMI cable helps maintain signal integrity.
Higher sampling rates preserve audio detail from capable sources, making audio clearer and more lifelike with suitable recordings and equipment. Listeners who value fidelity will notice reduced digital artefacts compared with lower-rate converters.
Multiple simultaneous outputs - thanks to integrated DAC and multi-port routing
Optical TOSLINK SPDIF, HDMI ARC, and analogue outputs (RCA L/R plus 3.5 mm jack) can output audio at the same time, with analogue outputs requiring the TV audio to be set to PCM or LPCM. Volume control for analogue and ARC outputs is possible via TV CEC when supported.
Use a headset and powered speakers together, or feed a soundbar and a hearing aid system simultaneously without switching cables. Flexible routing suits living rooms where several listeners use different playback devices.

❓ Frequently Asked Questions
Q: Will it work with any TV?
A: Only TVs that have an HDMI ARC function and an HDMI ARC port are compatible. TVs without ARC cannot be used with the extractor.
Q: Can it output 5.1 surround sound?
A: Optical and HDMI ARC interfaces support 5.1 channel output, provided the video source is 5.1 and the TV audio output is set to 5.1. Also ensure the TV optical port is configured to output compressed audio unchanged.
Q: Can TV control the volume of analogue outputs?
A: Volume for ARC, RCA and 3.5 mm outputs can be controlled through TV CEC, but CEC only works with HDMI cables and devices that support HDMI version 1.4 or above.
🏆 Our Verdict
Ideal for anyone wanting to route TV audio back into soundbars, amplifiers or headphones without rewiring multiple sources. The combination of HDMI ARC input, simultaneous analogue and digital outputs, and 192 KHz support makes the extractor a versatile bridge between modern TVs and legacy audio systems. While cheaper dongles exist, the broad compatibility and high-resolution support make this a practical, long-term addition for a living-room audio setup.
