Warrky 4K HDMI Audio Extractor — Optical, AUX, RCA

The WARRKY 4K HDMI Audio Extractor pulls high-resolution audio from an HDMI source and outputs it to optical S/PDIF, 3.5mm aux, or RCA so you can connect speakers, amplifiers, or headphones while keeping a 4K video pass-through.

This compact converter separates audio from an HDMI signal without degrading the video, making it simple to add dedicated sound equipment to TVs, consoles, streaming sticks, players, and projectors. It supports modern surround formats and high sample rates, includes essential cables, and is powered by USB-C. Use it when your display lacks a usable audio output or you want dedicated sound hardware for clearer music, movies, or games.

How does the extractor maintain video quality while sending audio to external devices?

WARRKY’s unit passes the HDMI picture through unchanged while decoding the embedded audio stream for separate outputs. It supports up to 4K resolution at common frame rates and complies with HDMI/HDCP standards for seamless compatibility.

• 4K 30Hz native pass-through; 4K 60Hz via YCbCr420 where supported
• HDMI 1.4 and HDCP 1.4 compliance to avoid handshake issues
• Preserves original video signal to TV, monitor, or projector
• Includes HDMI extender cable to help reach tight ports

What audio formats and outputs are available for different setups?

The device extracts audio and provides three output options so you can connect modern optical systems or legacy analog gear. It supports high-resolution PCM and common surround codecs for a broad range of content and audio chains.

• Optical S/PDIF output for soundbars and AV receivers
• 3.5mm analog output (plus included 3.5mm-to-RCA cable) for speakers and stereo amps
• Supports Dolby Atmos, Dolby Digital Plus, DTS and high-resolution PCM up to 192kHz/24-bit
• Sound channel switch lets you choose output mode quickly

Which devices and listening setups are compatible with this extractor?

The extractor accepts HDMI from a wide variety of sources and routes video onward while delivering audio to headphones, receivers, or powered speakers. It is purpose-built for home theaters, game consoles, streaming sticks, and media players.

• Inputs: TV sticks (Fire Stick), Blu-ray players, PS5, set-top boxes, PCs and laptops
• HDMI output to TV, monitor, or projector for video display
• Optical/3.5mm outputs for amplifiers, soundbars, passive speakers or headphones
• Useful when TV lacks optical output or when you prefer external audio processing

What’s included and what do I need to install it correctly?

The package contains the converter and essential cables so you can set it up right away; the unit does require external USB-C power to operate. No ARC/eARC support means it’s ideal for straightforward audio extraction scenarios rather than TV return-channel setups.

• Included: HDMI extender, 3.5mm-to-RCA cable, USB-C power cable for immediate use
• Requires connecting the USB-C power before operation to enable audio extraction
• Note: HDMI output does not pass audio to audio devices; it only forwards video
• Customer support available from WARRKY for setup questions or troubleshooting

Who is this for? If you own a TV, projector, console, or streaming stick and want to route its audio to dedicated speakers, an AV receiver, or headphones while keeping your screen’s video signal intact, the WARRKY 4K HDMI Audio Extractor is a practical, budget-friendly choice. It suits home theater builders, gamers needing clearer sound separation, multimedia creators, and anyone whose display lacks a convenient audio output. Avoid this unit only if you require ARC/eARC pass-through from the TV or advanced matrix switching functions.
