Sky + HD box IS outputting DD via HDMI!
Hi, can anyone advise on this please? I have a Sky + HD box (the latest smaller one with the larger harddrive) connected to my Pioneer VSX921 receiver using a HDMI 1.4 capable cable ONLY (I am not currently connecting using a seperate optical or coaxial cable for sound) so the sound output is definitely being fed via HDMI.
When watching standard def channels outputting stereo signals, my Pioneer receiver (which is set to auto for sound selection), chooses Pro Logic and works fine.
When selecting a HD channel with DD output (as shown in the Sky banner as DD), my Pioneer receiver is auto changing its sound output to DD and the 5.1 speakers are lighting up on the receiver's display. Listening to the sound, I can confirm that it does indeed appear to be delivering a full 5.1 dynanmic sound.
What I don't understand though is how this can be! Every forum and online post, What HiFi mags reviews etc etc all say that DD sound can only be supplied via optical or coaxial lead (under you have a Sky HD box without PVR). I even just called Sky to see if they have recently released a software update: they didn't seem to know and just said if I'm getting DD via HDMI then be glad!
Am I missing something here? Has anyone else found they can receive DD via HDMI on a Sky + HD box?
And finally even though I do appear to be receiving DD via HDMI, are there any benefits to sourcing my DD sound via optical from my Sky+ HD box anyway?
