Audio Extractor for HDMI Sources

The ESTONE HDMI Audio Extractor Converter 2.0 5.1CH separates audio from an HDMI signal while passing video through to a display. It accepts one HDMI input from devices such as Blu-ray players, game consoles or streaming sticks and provides simultaneous HDMI video output plus audio extraction. The unit is intended for users who need to route sound to an external audio system that lacks HDMI inputs.

Three Selectable Audio Output Modes

A physical switch selects between PASS, 2.0CH and 5.1CH modes to match the connected audio equipment. Extracted audio is available simultaneously on an optical Toslink SPDIF port and RCA left/right stereo analogue outputs. This flexibility allows connection to modern AV receivers via optical or to legacy amplifiers and active speakers via analogue RCA without additional adapters.

Simple Inline Installation

The converter installs inline between the source and display using standard HDMI cables and requires no software configuration. Power is supplied via an included USB cable, so a spare USB port or charger is needed. Ensure the audio mode switch matches the capabilities of the target sound system; an incorrect setting can result in no audio or stereo-only output from a multichannel source.

Questions about this item

Will the HDMI input port or audio output connectors wear out and need replacement?

The unit has no moving parts or user-serviceable components, so routine maintenance is not required and no parts are designed to be replaced.

What limits continuous operation when the extractor runs all day?

The only specified constraint is the three audio mode options — PASS, 2.0CH, 5.1CH — which define the output format rather than a thermal or bandwidth ceiling.

How much heat or noise does the converter produce during extended use?

The device is passively cooled with no fan, so it generates no audible noise and only minimal warmth during normal operation.
