2x1 HDMI Switch Audio Extractor

The YINGHUA 2x1 HDMI switch audio extractor routes two HDMI sources to one display while pulling multichannel sound to optical Toslink, coaxial, 3.5 mm jack or HDMI audio ports. It suits home-theatre owners who need eARC return from a TV to a soundbar or amplifier without replacing existing audio gear.

Installation and common issues

Connect each source to the two HDMI inputs, link the HDMI output to the display, then run an optical, coaxial or 3.5 mm cable to the audio system. The AU-plug power supply must be seated firmly; a loose connection often causes intermittent audio dropouts or failure to negotiate 4K 60 Hz handshake.

Sustained-load behaviour

During extended 4K 60 Hz 10-bit HDR playback the unit maintains stable HDCP 2.3 compliance and consistent audio extraction across all output paths. Heat remains low thanks to passive operation, so no throttling or signal degradation appears over long viewing sessions.

Questions about this item

How can I confirm the 4K 60Hz signal is passing through after connecting my sources?

Check that your display shows a 4K 60Hz RGB 8:8:8 image and that audio plays from the HDMI, optical, coaxial or 3.5 mm outputs simultaneously.

Which cables and accessories are included versus what I must source myself?

The unit and its AU power plug are included; you will need to provide two HDMI input cables, one HDMI output cable and your choice of optical, coaxial or 3.5 mm audio cables.

Should I choose a model with eARC support or one without for my soundbar setup?

This version includes eARC and ARC on the optical, coaxial and HDMI audio ports, so it will pass lossless audio from a compatible TV to your soundbar or amplifier.
