AUDIO DE-EMBEDDING – HDfury Vertex glossary
Audio de-embedding takes audio carried inside the HDMI signal and makes it available through a separate audio output for integration with other equipment.
HDMI carries picture and sound together in one cable. De-embedding means taking a copy of the sound out, so it can go to a separate audio device.
It is like pouring some juice from a mixed drink into a second glass: the drink keeps going, and you get a glass of juice too.
On the Vertex, the copied sound comes out of the small D/A jack, as analog stereo or optical digital audio.
Can the HDfury Vertex extract audio from HDMI?
YESYes. The Vertex copies HDMI audio to its 3.5 mm D/A jack: analog stereo, or optical (mini-TOSLINK) up to 5.1 Dolby/DTS, while the HDMI outputs keep their sound. Lossless formats such as TrueHD stay on HDMI only.
How to use it with the Vertex:
- Plug a 3.5 mm stereo cable or a mini-TOSLINK cable into the D/A jack (p.105).
- Let the source send 5.1: use an EDID table with 'SPDIF' or 'All Sound' in its name, or the Automix 5.1 Multi flag (p.15, p.28).
- Check the incoming audio in the USB GUI lines AUD0/AUD1 (p.27).
- To silence the TV on the BOT output, tick MUTE BOT TX AUDIO on the CONFIG page (p.42).
What does this mean in a real AV system?
This is useful when video needs to continue over HDMI but audio must also be fed to equipment that uses a separate audio connection or a different signal path.
This page is part of the Vertex Glossary: a practical explanation of the technologies and controls used around the Vertex HDMI signal chain.

Does the HDMI output lose its sound when I use the audio jack?
No, not by default. If you want the TV on the BOT output to be silent, turn on MUTE BOT TX AUDIO on the CONFIG page (p.42).
Why would I de-embed audio instead of using HDMI?
It helps when your amplifier or soundbar has only an optical or analog input, or when an older receiver cannot pass the video you want. Lossless formats still need HDMI (p.104).
