Hi

I have spent many hours over the past weeking trying to figure out why my Onkyo receiver (TX SR508) will only display a PCM fs:48KHZ audio signal, to no avail.
I have a brand new Toshiba 3D Bluray player (BDX3200KY) connected to my Panasonic Viera TV and the TV connected to my Onkyo (TX SR508) Receiver , all via HDMI cables.
Regardless of the TrueHd audio format on the BluRay disc , when playing them in the Toshiba player , my receiver will only output the same signal (PCM fs:48KHZ)
I have a second Bluray player (non 3D Panasonic) also connected (via HDMI) directly to my receiver and this plays all True HD , DTS HD Master etc formats perfectly.
I have tried adjusting settings on the receiver , the BluRay player and the TV without success.
Has anyone else encountered this and can anyone offer a solution ? (I have read that connecting a separate optical or coaxial cable could overcome this and am happy to try this if someone can confirm it works)

Optical or coax won't give you HD audio.

Most likely a setting on the Toshiba unit I would've thought. It might be set for PCM output rather than bitstream or somesuch.
    

Pretty sure I get AC3 just fine over optical, even when playing BluRay's via my PS3.

The problem is AC3 is not HD audio. The PCM could be lossless HD. The thing is that if the audio is passing through the TV, that will probably affect the formats the player will output. I second the suggestion to hook the player straight to the receiver, at least for troubleshooting.

I missed that bit. TVs will NOT pass through HD audio (at least, no TV I've come across).

The HDMI connection to the TV will negotiate the highest common format supported by both devices, which is most likely going to be Dolby Digital 5.1, which the TV will down-sample internally to standard stereo. The output _from_ the TV will only be this downsampled signal, they will not pass-through the source audiostream.

Is the player decoding to PCM? See if there is a setting in the player audio out for this.


And please confirm how you have it set up?

Are you going HDMI between player and receiver IN, and then HDMI from receiver OUT and the TV?

Thanks for the replies. The Toshiba can only accommodate one HDMI and that is already connected to the TV (it has to be to provide a 3D image)
I have checked the audio settings for the Toshiba player and it is set on PCM however the menu setting does not allow me to change this (ie it is set on PCM without being able to choose any other options)

I am aware that optical or coax cables will not provide HD audio which is why I don't want to pursue that option (the explanation provided in another forum was that by connecting an optical cable you would 'force' the system to use the HDMI cable and thereby provide HD audio to the receiver- however I'm not convinced)

Re "Are you going HDMI between player and receiver IN, and then HDMI from receiver OUT and the TV? "
Yes that is how it is set up

Didn't you just say that you had it player to TV IN, then TV OUT to receiver IN? I don't think you'll find a way to get this to work. Maybe with a splitter?

Looks like your bluray player is decoding the audio file and passing the raw audio information across to your receiver.  That's actually fine, it's the same info regardless of your player decoding it, or passing the still 'zipped' audio file to the receiver to do the decoding.  In essence I wouldn't worry about it.  However, if not seeing some decoding lights up on your receivers screen is ripping you up, then you need to determine why your bluray player is decoding to PCM and how you can change that.
  
As an aside, if you are after 3D viewing, then:
You need to connect 3D capable bluray player to a 3D capable receiver via 3D capable hdmi cable.  The connect the 3D capable receiver to the 3D capable TV by 3D capable hdmi cable also.
You can't go hdmi to the tv and expect the TV to pass HD audio back to the receiver via hdmi or optical etc.

Thanks , looks like I'm going back to the supplier of the Bluray player and ask them about switching the audio on there (specifically why it won't allow me to do it). Everything else is fine , I'm viewing BluRay in all its glory and have just forked out $$ to buy Tron Legacy on 3D BluRay but can't enjoy the HD audio that goes with it.

Actually Ive just reread UberGeek's response above and I do have the Bluray connected directly to the TV via a 3D HDMI cable so I'll try connecting it to the receiver and then buy another 3D HDMI cable and connect it from the receiver back to the TV . That should hopefully work

If you run the Toshiba BluRay via hdmi to the Receiver, then the receiver via hdmi to the TV. Can you set the video processing in the Receiver to pass-through and see if that leaves the 3D video signal intact? I won't hold my breath, because manufacturers would find it harder to sell the next generation of receivers if it did, but it is something you can try without added expense because you already have the cables.

Edit: Oh, and your thread title is very 'SHOUTY'.

Will try tomorrow once I've bought a second 3D HDMI cable and post the results

PS Sorry about the upper case subject , didn't realise it until after I'd posted it.

FWIW - Onkyo have recently (2-3 weeks ago) released firmware updates for some of their units relating to HDMI quality issues.

Got this sorted now (by reconnecting the existing HDMI cable direct to the receiver which then allowed me to amend the audio settings on the Toshiba player) so thanks for the responses . The results sound and look brilliant.
