I wonder how many others are having the same problem that I am having with the Blu-ray version of Wall-E.
I use my PS3 to play this film via the optical for the sound into an Sony DAV-DZ830W amp/dvd player(18 months old) but the film will only play in Dolby Pro Logic as my amp cannot decode the DTS signal that is set on the output language for the disc.The PS3 is set to only output DD 5.1 in the options menu as there is no point in ouputting DTS and it states that it will only output what it is set too.There is no option on the disc to output DD 5.1 so I have the quality picture(which is stunning)and the poor sound.Standard dvds output in DD 5.1 ok,will be a bit put off to buy more Blu-Ray discs if the only sound I can get is DPL.
But if anybody has any ideas as to resolve this without buying a new amp then I would welcome the advice.

Try setting the blu-ray's menu to Dolby TrueHD, which I believe is an option for this disk (I don't have a copy myself). The chip in your Sony should identify that data stream as DD 5.1.

Your PS3 should be set to DD 5.1 too, if it needs changing.

The DAV DZ280W does support DTS. See Tech specs here, or manual here (P7 under copyrights)

Despite what the pack label and menu says the Blu-ray version of Wall-E actually has a DTS-MA HD track - there is no DD 5.1 track. (There is a DD 2.0 audio description track.)

For PS3 owners you could set the PS3 to set BD Audio Output Format (Optical Digital) to Linear PCM. This should result in the PS3 decoding the DTS-MA track and sending a 5.1 output to your receiver as LPCM. You won't get a DTS logo on the amp but you will have the correct 5.1 sound.

Having stated the above I was under the impression that if you tried to send a HD DTS signal via optical it should still work but only send the "core DTS" info, (due to the bandwidth limitations of Digital Optical,) which is enough for 5.1 at standard definition quality.

Oops thought the OP meant 'normal' DTS (which the Z860 does support). Didn't realise he meant DTS-MA HD audio. Strange decision to go with no Dolby Digital or Normal DTS track, what about all those people with legacy amps that only deal with PCM2.0 or DD5.1 or DTS5.1?

Well I still do not know where it is going wrong,but thanks to dwhite for the heads up on the DTS(totally forgot it existed as all I use amp for lately is for the DD 5.1 on sky movies).I put a standard dvd into the PS3(Back to the future)and selected the DTS soundtrack and the logo on the amp flashed and began playing the DTS audiohowever it still does not play the wall-e one.Is it as dwhite say's that because it is a DTS-MA hd audio track it will not play?.If so then this is a bit stupid as lot of people will only have a standard decoder and as so is no bloody goodP.s have enabled all optical sound outputs on the PS 3 now.Any other ideas pleas-e feel free to let me know,cheers

In the audio setup of my PS3 I have DD and DTS ticked and when I play anything with DTS-MA or Dolby True HD it downmixes to 5.1 of either format.

This is an optical connection to a 6.1 Denon amp

Thanks for the reply tomconti from what I have read on the web it should downmix but for some reason is does not.I have tried ticking all the boxe's in the setup for optical out and unticking but it is still the same.I think that it could be something to do with the disc but I do not know anyone else with a copy and similar setup

The audio set up options are sometimes confusing.

I have mine setup so that I can select either DD or DTS as some discs have only 5.1 for DD but 6.1 for DTS .

However my DTS cd's do not play unless I go into the audio menu and change some settings.

Try ticking DD and DTS but remove the LPCM options .

There is also a "music settings" menu that you could alter.

I cant remember offhand what I did but check both menus

Did you play about in both "music settings" and "sound settings"?

Edit- just occurred to me.

Not sure about Sony amp but my Denon amp has an "auto" setting on it so that the amp outputs either DTS,DD or DPL.

If the "AUTO" setting is not on when a different sound format is played the amp goes silent.

I would suggest that your previous lack of interest in DTS may have lead you to change a setting on your amp that may not have mattered until now.

You could have the Dolby set to ON and so DD and DPL will output but DTS wont play out properly.

Check the front of the amp to see if you can find a setting that may adjust this

Edit- checked the manual and you need to press the "soundfield" button on the remote until "auto format direct multi" appears on the display and that should do what I said in the paragraph above

Sounds like you have it set to one of the many other options it has

Thanks again for the reply tomconti,have looked through the manual and gone through everything.

Have done this also and all films and games with a DD 5.1 run ok and sound superb without having to select anything.I think I will put it down to the fact that the disc is the problem.It wouldn't be too bad if I could actually get in touch with the manufacturer of the disc to ask questions

Just found this on the review of the film stateside and would probably count as the same over here.
The Audio: Rating the Sound


A DTS-HD Lossless Master Audio track is offered for 'Wall•E,' in 6.1 Surround (48kHz/24-bit). (Note: The track is incorrectly labeled as 5.1 Surround on the packaging.) There are no other mixes offered (not even standard Dolby Digital or any other foreign language dubs or subtitles. The audio is superb, delivering a fully immersive experience that is sure to dazzle.
Think I would like my money back now as thay are saying on the package 5.1

Well it looks like I have finally managed to crack it,I was watching I am Legend on BluRay and was having the same problem as Wall-E.So after a quick google on PS3 Bluray DD problems(realised it cannot be the disc as it happened again)I found a quote not too dissimilar
to hardeeps suggestion but it actually says
Go to the the 'Settings' menu on the PS3's XMB and then 'Video Settings', find the 'BD Audio Output Format (Optical Digital)' option and make sure that 'Bitstream' is selected.
I now get pure DD 5.1 and a DTS 5.1 on Wall-E.

Many thanks for all your replies guys I hope this helps somebody else who has this problem

Unfortunately because of the bandwidth limitations of optical audio connectors you won't get full HD audio, (Dolby TrueHD, DTS-HD or DTS-MA) bitstreamed - you would need to pass sound via HDMI or use the PS3 to decode it.

Trust me there is a noticable difference between listening to the full HD and the "reduced" signal you are getting. To give you an idea the core signal that you're bitstreaming has a maximum bandwidth of 1.5Mbps whereas as TrueHD as maximum of 18Mbps and DTS-MA 24.5Mbps.

If you want high def audio from your PS3 using the optical connection you must not bitstream it - the PS3 has to decode it and send it as LPCM.

You still won't get HD audio via optical even when LPCM is selected, LPCM will only give you 2.0 - HD audio is only available via HDMI (LPCM) on the PS3.

Thanks Hardeep but all I am bothered about at the moment
is gettin DD 5.1 and DTS,the minimum for an amp to decode the above is £300 and I am not going there.It's the same quality of sound I was getting of DVD and I was more than happy with that.Maybe in a couple of years I will look into itOptical is the only way at the moment but thanks for the advice
