Overview
A living room rack or a media cabinet under the TV is where this extractor earns its place, sitting between an HDMI source and an eARC soundbar. It reads the audio from the incoming HDMI signal and sends it out over HDMI to a soundbar or AV receiver with an HDMI input, while the video continues through to a compatible display. The unit auto-detects eARC when the TV apps or external devices are in use, and the audio format can be set to two, five or seven channels.
Buyers reach for this when a soundbar needs eARC audio from a source that does not deliver it directly. The box handles the current HDMI feature set, passes Atmos and DTS through, and includes the power supply needed for most outlets. Its one hard limit is the output side: audio leaves over HDMI only, so a soundbar with just an optical input has nothing to connect to.
Who it's for
A home theater setup where a soundbar or AV receiver takes audio over HDMI and the source needs to hand eARC audio off cleanly. The box suits that chain because the video flows on to the display while the audio is routed separately. An optical-only soundbar owner should look elsewhere, since this unit has no optical output.
Pros and cons
- Pulls eARC audio out of an HDMI source
- Passes Atmos, Dolby Digital and DTS through
- Selectable two, five or seven channel audio
- Handles 4K at 50/60 Hz with HDR
- No optical audio output
- Soundbar setup may be required for best results
- Two audio channels listed in the spec table
- Video and audio cables not included
Performance notes
The result depends on the handshake between source, extractor, soundbar and display. eARC detection happens automatically when the TV apps or an external device is active, but the soundbar has to be set up to accept the incoming signal. The audio format switch decides how many channels reach the soundbar, so a mismatch there, not the box itself, is what usually leaves a channel silent.

Frequently asked questions
Is the Orei HDA-929 an HDMI splitter or a switcher?
Neither. It takes one HDMI source, extracts the audio from that signal and sends the audio out over HDMI, while the video passes through to a display. It does not add inputs or send one source to two screens.
Can I connect this extractor to a soundbar with an optical input?
No. Audio leaves the unit over HDMI only, and the listing states there is no optical audio output. The soundbar or AV receiver needs an HDMI input.
What audio formats can the HDA-929 pass through?
Dolby Digital and DTS pass through, along with advanced formats including Dolby Atmos. The unit also offers selectable 2 CH, 5.1 CH and 7.1 CH audio format settings.
Does eARC work automatically with TV apps?
The unit automatically detects eARC when the TV apps or external devices are in use. Proper TV and soundbar setup may still be required for the audio to come through as intended.
What comes in the box with the HDA-929?
The package contains the HDA-929 audio extractor, a 100 to 240 V power adapter with a US plug and an adapter for international use, and a user manual. HDMI cables are not included.
