HDMI Audio – HDfury Vertex glossary
Lossless formats pass through HDMI without being compressed or downconverted by Vertex.
HDMI does not only carry the picture: the sound travels in the same cable.
The Vertex passes that sound on to your TV or AV receiver without shrinking or changing it.
Big lossless formats, like Dolby TrueHD or DTS-HD Master Audio, only reach your receiver over HDMI, not over the optical or analog jack.
Does the HDfury Vertex pass Dolby Atmos, TrueHD and DTS-HD over HDMI?
YESYes. HDMI audio, including lossless formats and Atmos, goes out of the HDMI outputs without being compressed or downconverted. Your player only sends what the EDID offers, so pick an EDID with full audio (p.104, p.111).
How to use it with the Vertex:
- In Automix, tick the 7.1 Full flag, or in Custom choose a table named 'All Sound' (p.15–17, p.28).
- RS232 alternative: #set edidaudio 71 (p.50).
- TV on one output, AV receiver on the other; CONFIG > MUTE BOT TX AUDIO silences the BOT output if needed (p.42).
- Check the incoming audio in the GUI AUD0/AUD1 lines (p.27).
What is it?
What happens to audio carried inside HDMI.
Why would you use it?
Useful when an AVR or processor downstream should receive the original HDMI audio.
Inside the HDMI chain
Lossless formats pass through HDMI without being compressed or downconverted by Vertex.
Do not confuse this with…
Audio extraction is a separate function from HDMI passthrough.
Common questions
Does the Vertex downgrade Dolby TrueHD or DTS-HD MA to Dolby Digital or DTS?
No. The Vertex does not compress or downconvert the incoming audio; lossless audio goes out through the HDMI outputs only (p.104).
Why does my player only send stereo through the Vertex?
The player chooses its audio format from the EDID it reads. In Automix mode the EDID can report only the audio both outputs share; the 7.1 Full flag or a CUSTOM table named 'All Sound' makes it report full audio (p.15–17, p.28).
Can I have picture on the TV and sound on the AV receiver?
Yes. Connect the TV to one output and the AVR to the other; CONFIG > MUTE BOT TX AUDIO can silence the bottom output if you want sound only from the receiver (p.42).
