Problems getting my Onkyo 606 to accecpt a 1080p signal from my PS3

[admin_exported]

First post, so here goes:

I have an Onkoyo TX-SR606, and am using a Playstation 3
as the source (games, Blue Ray and DVD's etc) and outputting to an InFocus
In76 Projector and a set of Mourdant Short 5.1 set of speakers.

I am having trouble running the system on anything other than 576 video
output. In the past I have been able to manually set the Playstation to output to 1080i, and the
system will display, but not to 1080p. However once the system is powered
down and then back up again it will not now even accept these settings, and the receiver indicates that there is no source signal,
and I have to re-set the source back to 576 to get a video signal. Unfortunatley even this does not work now.

I have tried running the projector directly from the Playstation, and all
video resolutions work (i.e. 1080p works fine), so I can only conclude that for some reason the PS3 on receiver are not talking to each other. I have been in touch with Onkyo Europe and their UK help desk, and it has been suggested that there may be a handshake peoblem, but no advice on how to fix.

The recever is set to 'Through' for HDMI video input, so as far as I understand the video signal should just be passed from the PS3 to the projector without any probs. I have also tried various settings on the PS3, but no joy there either. I have done a search on past posts and, other than realising that my audio may not be working as well as it could (thats for another day!), havent found much. I can only assume from this that there shouldnt be a problem, and that I may well have missed something basic.

So, any suggestions would be gratefully accecpted.

Anybody got any thoughts on this?

Hopefully I am not the classic new member with daft question.

Been tearing my hair out, and suspect I have missed something simple!

taken from else where

The following is assuming a PS3 and a 605 amp. It is relevant to the
higher end amps but the menu options may be different. I can only speak
for the hardware I have. OK here goes.....

First a bit of background knowledge on the connections and audio formats:

Optical connector (sometimes called TOSLINK)

This connection has limited bandwidth and can only supply

Dolby Digital (Bitstream)

DTS (Bitstream)

PCM (2 channel stereo)

HDMI connector (in brackets is the minimum revision of HDMI needed for that format)

Dolby Digital (Bitstream 1.1)

DTS (Bitstream 1.1)

Dolby Digital plus (Bitstream 1.3)

Dolby TrueHD (Bitstream 1.3)

DTS HD (Bitstream 1.3)

PCM Multichannel (1.1)

Ok, from the above list you can see that HDMI can do a lot more than optical. So, surely this is the best way to go, correct?

A little bit about PCM (and LPCM) and bitstream.

PCM stands for (Linear) Pulse code modulation. This is an uncompressed
stream of audio. As it is uncompressed, a lot of information is sent
along your interconnect cables. This is why the limited bandwidth of an
optical connection only allows a stereo PCM signal to be carried.

Bitstream is a compressed signal (sometime lossless, sometimes lossy).
This is why a bitstream 5.1 signal can be sent over optical. Because it
is compressed, effectively more information can be sent. However, even
compressed, optical cannot handle the new HD formats as they still
exceed the optical connections limits.

Now, for bitstream to end up coming out of your speakers it has to be
de-compressed. This can happen in your player or in your amp. The
difference? Well, if you decode in the amp it will tell you which
format it is decoding and outputting. If it is decoded by your player,
the amp is only getting uncompressed sound, it does not know what
compression method was used (DolbyTrueHD, DTS HD etc). This is why,
when you decode the audio in a player the amp will only show 'Multich'
and the pretty lights on the amp will not light up.

Ok, got that, so what should I use on my PS3?

Well, here is the issue. HDMI is the best (looking at the above
comparison) for carrying the sound. So, you only need the PS3's HDMI
cable connected to your amp. However, there is an issue with the PS3
and bitstream. It cannot send any HD audio format bitstream via HDMI -
it just doesn't do it. Some say it is due to a custom HDMI design in
the PS3 that doesn't allow it, some say Sony just haven't bothered and
it can be updated in firmware. Who knows? All we know is, it doesn't at
the moment so that option is out. And optical is out as that by design
cannot.

Now, the PS3 can decode all of the audio formats (standard and HD) and send via PCM.

Right, so what do I need to set the PS3 and Onkyo to for the 'best' solution?

So, from above we can deduce that HDMI and PCM (in the case of the PS3) is the best option. To do this do the following:

Turn on the amp and select the source that your PS3 is connected to (DVD, Gam/TV etc)

Turn on your PS3

On the PS3:-

Select Sound Settings

Select HDMI

Select AUTO

Check that all the DD, DTS and a number of PCM (all the way up to 7.1) are ticked.

Save the settings

Go to the BD/DVD settings

Select audio output format as PCM and save the settings.

On the Onkyo:

Press Setup

Select Input/Output Assign -> HDMI Input

Go to the line for the source that you want the PS3 to appear on and
set it to the HDMI socket that you plugged the PS3's HDMI cable into
(IN1 or IN2).

Press return

Select Digital Input

Check that the input you assigned your HDMI to (above) states 'HDMI'

Press setup

All done!

Been through this, although it seems to be mainly audio.

Had another go over the settings this eve and no joy. Head still firmly being scratched!

It's possibly too obvious, but what happens if you set the Onkyo to Auto? I works for me (i.e. PS3 hooked into 905 with a decent HDMI cable).

professorhat: It works for me (i.e. PS3 hooked into 905 with a decent HDMI cable).

could it be that? perhaps the OPs HDMI cable isn't 1.3 compliant? Just a stab in the dark.

Prof, will try auto this eve, but pretty sure Ive done it already.

The HDMI cable Im using is a 7.5 m version of this one from Onkyo to Projector:

http://www.hificables.co.uk/11305/IXOS-XHT458-HDMI---HDMI-cable.html

It works direct from the PS3 to the projector, but not through the Onkyo

and the 1 m version of this from the PS3 to the Onkyo:

http://www.hificables.co.uk/11429/IXOS-XHT288-HDMI-to-HDMI-cable.html

From what I understood when buying them they should both be fine.

hmmm, just throwing this out there, I've no idea whether this is even remotely accurate but I wonder if by setting the amp to throughput the HDMI signal you're creating a total signal path length of (at least) 8.5m and that this is where the problem lies? What's the other option on the amp, other than "Through"?
