DIY splitting Audio and Video signals in HDMI

[andrep]

Is it possible to split the audio and video signals in HDMI connection?

I mean in a passive way, like knowing the HDMI pin-out and building a Y-cable?


What sort of AUDIO format would we end up with?

SPDIF? AES?

Not sure if what you're asking is possible, you'd have to detemine what pin does what.

yes, but also the format

if there's spdif coming out of the pins, one could have an spdif output in most modern laptops

great link!

It may be easier to find out which pin is audio and video on DVI-D and track it back to HDMI

I had a conversation with another staff member, you should be aware that HDMI is SO tweaky - splitting it can be done but the signal strength is so low that it's a shoot at best.

Yes

I went to the sites you suggested and 8 ch of HD sound cant be over a 'traditional' format.

all the best
