Hi there all,yes you all have valid points,just to say that i have a ps3 connected up to my dsp z9 via optical out ,which unfortunatly the amp does not have hdmi,but if i set bitsream out,the sound goes to the amp in dts and dolby digital,if i select lpcm,the amp will not decode dts or dolby digital,so what im saying is you have to select the ps3 to bitsream if you are connecting up via optical to get plain dts and dolby digital,which i must say is a massive improvement still in surround sound quality as the blueray discs are less compressed tham dvds are,cheers guys for the information you have posted,its good to read other peoples views
Hi Trevor,
It sounds like you are saying that the PS3 CAN Bitstream Dolby TrueHD and DTS Master Audio to a suitable amplifier and that Sony has decided in their wisdom that they wouldn't let anyone know. I don't get that.
What do you mean by:
'Checking the bitrate tab stops the PS3 doing the work! You will not find any info on this off SONY.'
I have heard differences in VOLUME when switching between the PS3 Bitstreaming DTS-MA from a BD (i.e. it is sending only the 'core' at 1.5mbps) and when sending it LPCM (usually quieter but much higher bitrate), but this is rectified by turning up the amp volume a touch. Everytime, i can hear the improvement in the DTS-MA track sent as LPCM from the PS3.
Please clarify...

Hi Raihan, the PS3 cannot send the data in Bitstream. BUT will send the data unprocessed down the HDMI cable to the Onkyo for it to process itself if you set it on the 'Bitstream ' tab!
I wonder if selecting LPCM on the PS3 means it processes the uncompressed PCM track in some way before squirting it over HDMI whilst selecting bitstream sends it unmolested. Perhaps that's why it sounds so much better.
Got to go, half way through watching Good Luck Chuck - BLU-RAY Version.
Why don't you all try it for yourselves?

Well, trevor, you've completely confused me.
trevor79:the PS3 cannot send the data in Bitstream. BUT will send the data unprocessed down the HDMI cable to the Onkyo for it to process itself if you set it on the 'Bitstream ' tab!
So it cannot send it, but it will send it...

Ditto above!
Makes no sense to me. Either its 'zipped' in Bitstream or 'unzipped' in LPCM...
BTW, Professorhat, i got the Transformers Blu-Ray recently and the Dolby True HD track was just as loud (if not, louder and much better) than the DD of the DVD. But then, i do use the Yamaha RX-V3800 and not Onkyo.
Trevor79: when you have set your PS3 to Bitstream and play a BD with either a Dolby TrueHD or DTS HD-MA soundtrack, what shows up on the front display of your Onkyo? Does it readb 'Dolby TrueHD'/'DTS HD-MA' or 'Dolby Digital'/'DTS?'

Ok, taking into consideration all of the above,how feasible is it then to invest in a stand alone player (which is clearly the line of thinking Sony had in mind for us when they released firmware updates for HD audio on the PS3), knowing that the picture and audio quality from these players are far superior to the PS3.But, will it be worth it to invest in a mid range product (Sony/Panasonic) or go high end (Denon/Yamaha) and experience the way BD's were supposed to.Do I hear that voice of reason again.............
heres my two pence worth, with an 875 and ps3:
just tried blu disk of master and commander, watched the same part at the beginning on the two settings,lpcm and bitstream.
With bitstream the onkyo 875 display reads: DTS 5.1
With lpcm the onkyo reads: Direct then PCM 48khz.
Important part-the sound, although quieter with lpcm it is far more detailed and if you turn it up a notch to even the volume up between the 2 settings, the hairs on the back of your neck stand straight up when listening to that first volley from the guns.Only half way up with the bitstream setting i am afraid, so hats of to the proff.

With the Batman Begins BD on the 606 LPCM reads: DVD Multichannel. Also noticed that if I turned up the volume control on the PS3 to max.there is an improvement of True HD over DD. What should the settings be on the Listening Mode Presets on the onkyo menu?

Hi guys, your posts gave me food for thought as well.
Firstly let me say that I have a good ear for sound/music and have been tweaking / modifying equipment for about 25 years.
Back in mid 2007 when the first Onkyo 875's came out many people paired with it with the PS3. Indeed I got info off forum posts from then on how superior the sound was on Blue Ray by using the Bitstream setting on the PS3 instead of the LPCM!
The test disc was Casino Royal which still stands as a good BR production. Everyone scratched their heads as to how it could be so.
It was thought that the PS3/bitstream handles this by recognising it is not suitable for it so uses the LPCM line anyway, BUT on the most direct path it can taking shortcuts in the chip set circuits in the PS3. After all they should both sound the same otherwise!
Now I don't know if this is true or not as without the circuit diagrams and configurations of the processes one can't tell, and Sony won't say.
This afternoon I have been doing some A/B comparisons on 'Tears in the Sun'.
Setting thing back to LPCM on direct and Multi Ch modes I found the overall sound brittle and harsh, especially gunfire. The explosions felt a bit limp, and yes I had set volumes to the correct sound levels. Score 5/10
Switching over to Bitstream, playing DD-Digital Direct, DD THX cinema, Sound went from being 'thin' to full bodied without any loss of detail, just great presence. I had to turn the Sub down as it was overpowering, it really shook the room unlike before. Score 9/10
No contest for me, but I do have floorstanding speakers who's cones are fed with a exceptionally pure signal that move a lot of air when asked to.

Just noticed Trevor mention Bitstream from PS3 in another thread and a quick search led me here.
Just wondering what the current state of play is with Bitstream HD audio from PS3. Still a no go? Does Trevor's 'fix' work? Or has there been an update to allow bitstream since?

No update to allow it I'm afraid. Personally, I always found the sound better on the PS3 when set to LPCM (and I did a lot of testing on this as well), but others like Trevor prefer it when set to Bitstream. It doesn't really concern me any more as I now use my Sony S550 for Blu-Rays, but if you're in this situation I would suggest trying both, ensuring you select the HD soundtrack on your disc and seeing which you prefer.

This is one of the most maddening threads I have ever read.
Essentially, two different and contrasting opinions on HD audio; both are adamant they are right, and one must be wrong. As to what sounds best, you'll never win that argument!
As I understood it, from Sony instructions, the PS3 cannot bitstream HD audio. Anything bitstreamed MUST be DD or DTS as on old dvd's. This is an OBJECTIVE question of fact. It's a simple Y or N for the answer, no messing.
The argument is being clouded and confused by a SUBJECTIVE argument of what sounds best.
The answer to solving this is to go with what you prefer for the bitstream/LPCM debate.
However, the objective question of FACT about whether bitstream can pass HD in uncompressed mode still needs a conclusive answer. I'm surprised someone of authority here (WHifi) hasn't got the definative answer to solve this pain of a debate.
For the sake of sanity, PLEASE can the editorial team answer that simple question. I'm on the side of Prof etc. as the Onkyo and the PS3 show no evidence it can on the display tags. If Trevor is right (not deluded) then this is important news!
Can we sort this out!!!!!

If you set the PS3 to output Bitstream, and then play an HD soundtrack on a Blu-ray Disc, it will send a standard-definition audio signal out to your receiver, such as standard Dolby Digital or DTS 5.1, depending on the soundtrack.
If you set it to send LPCM, it will decode the HD soundtrack onboard, and send that out as multichannel Linear PCM - actually up to four two-channel datastreams - to the receiver.

Yes Andrew, that is what basically happens, but what happens with the signal is a bit more complexed.
There's no reason why bitstream should sound the same as LPCM. The digital audio replay architecture is different, and that means the sound may be different.
A digital audio signal has two elements - a data stream and a timing stream. Both of these end up at the DAC to create the analogue audio signal, and both need robustness and fidelity.
These streams are quite distinct, and take different critical paths:
The data stream starts at the disc, and ends up at the DAC.
The timing stream starts at the master clock in the PS3, and also ends up at the DAC.
The bitstream decoding process ONLY affects the data stream, and the DAC is receiving the right data, whichever decoding architecture is used.
However, this architecture MAY affect the path of the timing stream . With LPCM, the clock is in the transport, and the path takes the HDMI connection to the receiver and to the DACs. This is a tortuous path, and is full of degradation - like toslink but worse.
With bitstream, there's no clock associated with the data because its compressed, and the clock is regenerated IN the amplifier, just as it is with DD and DTS. This places the clock right next to the DAC, with robust and direct connection, you can't better that. This doesn't eliminate interference, noise and jitter, but it's a very big help. The same information is put out but one is processed by the player and the other by the AV amp. It's clear on listening to me that the Onkyo 875 does a better job of it.
So with bitstream there is an opportunity to minimise jitter, though this is ONLY achieved if the amplifier doesn't generate its audio clock from the players video clock, in the same way it does with LPCM. I think Onkyo don't, but other amplifiers might (I don't know). What I do find is the timing and 3 dimensionality is head and shoulders better with what is played out from the speakers. Now with the PS3 being such a big seller for Blue Ray I think this is very important.

Thank you Andrew!!!
Trevor, you go on about bitstream sounding better. BUT, its still bog standard Dolby Digital, or DTS.
You prefer normal bitstreamed DD or DTS to the HD LPCM on PS3. That's up to you.
But please stop telling us you can get HD sound this way. You can't.
The end.

I kinda thought that would still be the case, but I haven't paid any attention to this topic for a while so thought I'd check up. Disappointed but not really surprised

Just to kick the hive again...
I tested this today on my PS3 and found that Bitstream performed better for my system. When set to lpcm my rear channels didn't even have sound.
When PS3 set to lpcm the Onkyo display showed multi channel pcm and I got audio out of the two front and voice out of center.
When PS3 set to bitstream the Onkyo display showed digital dolby and dolby PLIIx and all speakers worked and the surround worked.
This was a standard DVD and did not have and HD-audio. Also, the interconnects were all HDMI.
Does anyone know how you can configure the Onkyo to actually put audio out of the HDMI? I have done everything in the manual and everything I can find on forums. I am trying to get rid of my center (voice) speaker and see if I can play this into the tv. It would look better on the wall without the center speaker and my tv has an excellent speaker system. Ideas?

Thought this thread had died.
Just so I don't start another war!
I have been doing extensive research on the PS3 and looking at why Dolby Digital Bitstream sounds so good.
The PS3 has the 9132 chip fitted which will not Bitstream the high quality audio formats, so apologies Prof and others on those points.
Here is a breakdown of the Vastlane chip family from Silicon Image
SI Vastlane 9132: (Gaming Transmitter) Supports Deep Colour but not the latest high-quality audio formats.
SI Vastlane 9133: (Dual Input Receiver) Enables HDTV's to display Deep Colour but does not support the latest high-quality audio formats.
SI Vastlane 9134: (Dual Input Transmitter) same abilities as the 9133 with additional support for the latest high-quality audio formats.
It is clear to see the evolution on these Chips from the 9132 put in the PS3 to the 9134 found in the newer crop of players.
It is seen on the dedicated Blue ray players that they all do Bit streaming on high quality audio formats.
Manufactures in the development research must have concluded that this path was one that needed to be offered.
One clear distinction to make is the PS3 achieves LPCM HD processing due to a software update, instead of processing through the 9134 - Bitstream or LPCM.
I am sure that on (PS3 LPCM) all the sound track info is not getting processes at the AV amp end. Now it is acknowledged by the industry that if disc players were asked to run computers they wouldn't work!
Set to Bitstream, even though it is in DD ALL the signal information is received. Manufactures have been addressing Jitter issues in the newer models along with internal interference on the circuit paths.
This probably indicates much of what is going on with PS3 LPCM processing.
SONY ..."The flagship Sony S5000ES is also the first Sony player to feature a Precision Clock Conditioner, designed to reduce the effects of jitter."
Now if it wasn't a problem why address this?
Perhaps it needed to be sorted if the player was to be doing the processing itself and then sending it out!
"All the components used are of the highest quality and include high-performance capacitors and digital-to-analogue convertors."
This player is currently regarded as one of the best that has been reviewed.
I would be surprised if there was big differences between Bitstream and LPCM on this player as problems appear to have been designed out.
Another player that is flying off the shelves at the moment is the Panasonic DMP-BD55.
"Like the entry-level 'BD35, this player is also Blu-ray Profile 2.0, DivX and x.v.Colour compatible. So why does it cost more? The extra outlay gets you upgraded audio parts, including new capacitors, a new 192kHz/24bit DAC and a couple of tweaks to the HDMI output to help reduce jitter."
This is What HiFi said about the DMP-DB50... "It's great that the player can decode high-definition audio formats by itself, but we preferred sending the raw audio data as bitstream over HDMI and letting our Onkyo TX-SR606 receiver do the decoding. It produces a more dynamic, powerful and spacious sound that really excites the listener."
On the Denon DVD-2500BT £800 "Excellent Blu-ray performance in every regard; excellent DVD playback; classy build quality" It only does Bitstream.
There is a pattern emerging here on the stand alone players. If you have a good AV amp receiving Bitstream it will get 100% of the data to process. And you can't better that.
What Hifi says in its test on the PS3 "Decoded HD soundtracks are relatively clear and open, but you get the feeling the PS3 is only scratching the surface. It has a tendency to sound bright and this lack of solidity and scale can make it sound lightweight."
I agree with the above, thats how it sounds to me. That's why I prefer DD Bitstream, do not lose anything in the track detail but it has the fullness, separation and presence.
SKY have you tried setting Audio out on the HDMI settings to the TV?

Trevor,
Don't loose the faith. It may seem like everyone is ganging up on you, but I don't think the jury is in yet. I agree with those that are reading the specs. and stating what the PS3 will and will not support, but thus far, the actual testing that we have performed is supporting bitstream. I would agree that it could also have some to do with the totality of the system and the PS3 is one component.
Anyways, I tested for hours today on my system tweaking everythink I could jiggle and I never got lpcm to beat bitstream. I am looking forward to working more with the more advanced new audio encoding because I suspect lpcm will probably do better there.
I did turn "Audioto TV" on but it didn't make any difference. I finally gave up and turned the center speaker to off and now have a blended phantom center. It sounds ok but still bugs me that I could not figure it out. I still plan to experiment with a direct toslink from ps3 to my plasma but I don't know if the ps3 will put audio out on both the hdmi and the optical audio at the same time.

No it isnt. it is telling you that you like the way something sounds, nothing more. Now, if id shelled out for HC kit and found HD audio quiet, id be confused and annoyed (tho i wouldnt necassarily be right to be) and instantly question whats up, but if someone sai dturn the volume up id try it, and see if i was hearing more detail than i could at a reasonable level with the non hd method.
Trevor, you are directly accusing sony of not declaring a major selling point. why would they do that?
I am going to wish i hadnt contributed, but still. I've had a good early morning rant.

Just to add a quick note here i had a problem with the transformers track on my ps3 and im using an onkyo 606 and on another site i found out if you turn off the dynamic range control setting on the ps3........ hit triangle while watching and its in av settings, it sorts out the quite no bass type problem. As far as im aware its a problem on the discs itselves but hey who wants that setting turned on anyway? it makes listening at nite easier!! Sorry but if im watching an action film its getting some pasty...........

I feel I have to pipe up and support al7478 in terms of liking the way something sounds. There's nothing wrong with choosing bitstream with the PS3 if you prefer it, just as there is nothing wrong in choosing Linear PCM if you prefer that. I did extensive testing on the PS3 and preferred the movie soundtracks when I set the PS3 to decode the HD soundtracks and send them to the amp via PCM. You (i.e. Sky1980, Trevor, and nameless others I'm sure) have done extensive testing and preferred the movie soundtracks when set to bitstream the Dolby Digital / DTS core soundtracks to the amp.
Like all contentious threads, there is no right or wrong answer for everyone here. Only the one which is right for you. So, as always, try both and go with the one you prefer.
