A compact extractor for sending HDMI audio to a soundbar, AV receiver or optical DAC while the picture holds its full quality. It does not pass ARC back from a TV, so it only works on the source side of the chain.

Overview
A metal box on the source side of the chain splits the audio out of an HDMI feed and hands the video on untouched. One HDMI input carries the signal in, the HDMI output continues to the display, and the optical and 3.5mm jacks feed a soundbar, receiver or speakers. The supplied power brick runs on either mains voltage with a plug adapter for travel.
Buying this makes sense when a display or projector has no audio output that suits the room, because the split happens before the signal reaches the screen. The picture passes through at full bandwidth with HDR intact, and the audio lands on optical or analog jacks. The one real limit is that it works one way only: it cannot take sound back from a TV over the return channel, so a TV as the audio source is out of scope.
Who it's for
Rooms where the sources sit in a cabinet and the sound system takes an optical or analog feed, and the screen only needs the picture. It also suits a desk setup routing console or PC audio to powered speakers. Do not buy it to pull sound out of a TV app, since the return channel is not supported.
Pros and cons
- Splits audio while video passes untouched
- Optical and 3.5mm outputs cover most soundbars
- Handles Dolby Atmos and DTS:X bitstreams
- Metal body with a small footprint
- No ARC, so no TV audio back
- Rejects 1440p at 120Hz and 4K at 30Hz
- No HDMI cable included
- Only two audio output types
Performance notes
The extractor reads the audio stream as it passes and sends it out the optical or analog jacks while the video continues at the same resolution and bandwidth. What comes out the far end depends on the source settings and on what the soundbar or receiver can decode, since the box passes bitstreams through instead of downmixing them. Feeding it a format it does not list leaves the audio silent rather than converted.

Frequently asked questions
What size is the Orei HDA-912 and will it fit behind a TV?
The housing measures 2.9 by 2.4 inches and weighs 227 g, so it fits in a cabinet or on a shelf near the source. It is cable mounted, meaning it hangs from the connected HDMI and power leads rather than screwing to a wall.
Does the Orei HDA-912 pass 4K at 30Hz or 1440p at 120Hz?
No. It passes 4K at 50/60Hz at YUV 4:4:4, and the supported list excludes 1440p at 120Hz, 4K at 30Hz, 1080p at 120Hz and 1080p 3D at 60Hz. Set the source to a listed format before connecting.
Can the Orei HDA-912 send audio from a TV back to a soundbar over ARC?
No. The unit has no ARC support and no return channel, so it cannot take audio from a TV. It extracts audio from a source device such as a console, player or streaming stick on its way to the display.
Which audio formats does the Orei HDA-912 send over optical?
The optical output carries LPCM 2CH, Dolby Digital 5.1 and DTS. Higher bitstreams such as Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X are supported by the extractor, and whether they reach the speakers depends on the decoder at the other end.
What comes in the box with the Orei HDA-912?
The box holds the HDMI extractor and its dual voltage power supply with a US plug plus an adapter for international use. No HDMI cable is included, so plan for one long enough to reach the display.
