Sky HD audio?

Iceman · 12 Dec 2010 at 18:20

Hi all just got hold of a new av receiver, connected sky Hdmi for picture and using optical for the sound. Does this not output in dolby?
When the Xbox is on picture and sound via Hdmi i get the Dolby light up, but when sky is on i get a pcm light. Is this right? Do different broadcasts send out dolby etc??

Thanks.

It depends on the program, not many are broadcast in dolby sadly

Are you using optical out from the Sky box or your TV? I got massive sync issues when I used optical out from the Sky box which were solved when I used the one from the TV.

And as above, Dolby is only transmitted with certain programmes to save bandwidth.

Using it from sky box to amp. Ahh right i see so its whatever the programme is broadcast in then? Not noticed any syncing issues so far.
Thought it was something i had done wrong.

Thanks for replys guys.

oddly enough my optical from my sky hd+ stopped working recently. it was still lightling up but my amp wasnt recognising it as a digital signal. swapped to coax and its been fine..

the amp should still report the signal as digital even if its not a broadcast in DD.

IIRC sky HD does not output DD (5.1) over HDMI, only on optical.

When sky is going through the amp its showing as PCM, when through Xbox 360 it shows the dolby sign (or something along those lines) Does that sound right? Im not too sure what the pcm means.

also when, you do get set it up over optical, the introduction voice(you know the 'whats next' voice) will come out of the stereo (L/R) speakers as opposed to the centre when the amp decodes stereo over HDMI. or theat could be just mine

The % of Sky customers connecting it to their HDMI AMP is going to be less than 2%. I can't see sky broadcasting their content is any HD sound format. Shame really

what. rubbish, they do transmit in DD all the time, all the films are and some of the american series are as well , what a silly thing to say.

dolby digital is not HD audio. Weather he meant real Hd or not i dont know, but that statement he made in that context is correct.

bullit in head · 12 Dec 2010 at 20:40

I was under standing he ment HD as 5.1., but if it'd DTS-HD or Dolby trueHD then fair dues . I withdraw that statment

Have you set the amp to take the audio from the optical input rather than HDMI ?

Schizophonic · 12 Dec 2010 at 20:53

The term "HD Sound" never got to the mainstream public. And Yes James.miller - HD sound to me is TrueHD and DTS-Master and to many others.

If you class HD sound as DD then its been around for ages in your sense.

but in the context of the OP, sky HD box's do not output DD over HDMI only over Optical, just saying

Yeah i have done that, it hasn't really made much of a difference though. Well not that i can notice anyway.

I shall view a few different channels when i can get the other half away from watching X factor lol.
See if any of them are any better, will they show on the amp with the dolby sign or will it stay with the PCM?

Put sky on a film channel, if it's a DD film it will show it when you press the i button.

PCM is a 2 channel signal, my amp upmixes this to dolby prologic 2 will your amp not do this also ?

Not too sure if im honest, i have just got hold of this... http://www.eu.onkyo.com/products/HT-S3305.html set up and im still getting used to how it all works.

As far as I can see, no-one has mentioned changing the setting of the Sky box optical from Stereo (the default) to Dolby D. Iceman, have you done this?

Services > Settings > Sound > Digital Audio Output

Remember to confirm the setting before exiting. Try the audio delay on 20ms if your Sky box has the option.
