VPFET HDMI Audio Extractor — HDMI to Optical & 3.5mm AUX Converter, 4K@30Hz, 5.1/2.0 Modes

The VPFET HDMI Audio Extractor splits audio from an HDMI feed and outputs it via optical TOSLINK or 3.5mm AUX so you can route sound to speakers or a headset while keeping video to your display.

This compact converter separates digital audio from an HDMI source without changing your video path, supporting up to 4K@30Hz HDMI video and multiple audio formats. It’s powered by a 5V USB input and offers three selectable audio modes for stereo or multi-channel output, making it useful when a TV or source device lacks a dedicated audio output or when you need to feed a soundbar, AV receiver, or headphones simultaneously.

How does this adapter handle different audio formats?

The unit provides three processing modes—2.0CH for two-channel stereo, 5.1CH for multi-channel via optical, and PASS to forward the original stream when other modes fail. Optical (TOSLINK) can carry surround formats like DTS 5.1, while the 3.5mm jack offers PCM stereo output suitable for speakers and headphones.

• 2.0CH mode: outputs stereo via 3.5mm analog.
• 5.1CH mode: outputs multichannel audio via optical port.
• PASS mode: relays the native audio if conversion modes don't match the source.

Will it work with my 4K devices and gaming consoles?

The extractor supports HDMI 1.4 with HDCP 1.4 and can pass 4K@30Hz video (RGB / YUV4:4:4). Some streaming sticks and consoles send only 1080p or have platform limitations—check the device specs—so certain sources may not output 4K through this converter.

• Compatible with Blu-ray players, set-top boxes, PCs, and many streaming players.
• Supports HDCP 1.4 protection for protected content playback.
• Note: ARC/eARC and TV-input-as-source are not supported.

How is the extractor powered and installed?

Installation is straightforward: connect your HDMI source to the extractor input, run HDMI out to the display, and choose the desired audio output (optical or 3.5mm). The unit draws power from a 5V USB supply—either from a USB port on another device or a separate USB adapter—so no external power brick is required.

• Plug-and-play: no drivers needed for basic operation.
• Powered via USB 5V port—low energy consumption.
• Compact form factor fits behind AV cabinets or near TV inputs.

What limitations should I be aware of before buying?

The extractor does not handle ARC/eARC signals and cannot output 7.1 channels; optical supports up to DTS 5.1 while the 3.5mm jack supplies stereo PCM. Also, some devices like certain Fire TV or Apple TV units may only send 1080p to external converters, so confirm your source’s output behavior.

• No ARC/eARC support—do not use in an ARC audio loop.
• Optical limited to 5.1 surround; analog limited to stereo.
• Not all HDMI sources will pass 4K through the device—check device specs.

Who is this for: The VPFET HDMI Audio Extractor is aimed at home theater hobbyists, gamers, and anyone who needs to route audio from an HDMI-only source to an external sound system or headphones. It’s a practical choice when your TV lacks dedicated audio outputs, when you want a simple and portable splitter for travel setups, or when adding a basic surround-capable optical feed to older AV gear.
