[Project] Dual Audio Output support (Nexus/Matrix/Krypton/Jarvis/Isengard/Helix/...)
A little bit off topic here, but maybe some of you have already tried this (or perhaps would like to try).

HDMI audio extractor > HDMI, optical, 2ch analogue
Link

According to the description, it extracts audio stream from hdmi input, and it can do 3 things:

1) passtrough -- nothing is done, just hdmi in to hdmi out
2) 2ch -- audio is extracted from hdmi input to and sent in 2ch stereo (obviously) to hdmi out, optical, and 2xrca (wonder what DAC is used and the quality, nowadays there are very nice surprises with very high quality DACs used in cheep devices from China)
3) 5.1 -- audio is extracted from hdmi input, and send to optical and hdmi out, no analogue. The optical supports DD 5.1 and DTS.

I'm considering one of these, as it would solve my scenario, as the 5.1 mode would be perfect to have audio at the amp and tv too, while the 2xRCA for stereo amp

Of course, there are many questions:

-- is the audio extracted to optical if tv is turned off, will it work then?
-- what is the quality of the whole thing, what are the limitations, if any?

Has anyone tried this already? The price is really low, so might be worth a try.
