What do I need to get to play the blu-ray dvd's in uncompressed audio?theo_1

A receiver with HDMi port.

yea, but does the reciever need to be 1.3 hdmi ? or does it matter?

A receiver with HDMi port.

I thought optical can output pcm too?

Some clarification...

Word of warning, a receiver that has an HDMI port may not be able to handle it... as there are some that are simply "switchers" and don't process LPCM audio.

Despite what anotherposter stated, thereare plenty of blu-ray titlesout there (I'd say over 75)with PCM soundtracks. Here is a great thread on picture quality which also lists the audio formats:

At this moment in time, you do not need HDMI 1.3 in any way. Any receiver capable of handling LPCM over HDMI will suffice. The only thing up in the air is the audio format DTS-MA (supported by Fox Studio films), which is currently unavailable to hear.A lot ofblu-rays(and HDDVD's) have this format on it, but there is no way of hearing the format as of yet. There are receivers that have recently been released that have the ability to decode it, but there are no players that have the ability to send it. There is a possibility that the PS3 will send the audio to receivers for it decode ("raw audio bitstream"), and in that situationyou will need HDMI 1.3. However, if the PS3 decodes it (as is the case with the other "high def audio" format Dolby True HD), then the PS3 will send it as linear PCM and you will not need HDMI 1.3.

I just recently set-up the Onkyo 605, and I am very impressed (That's putting it mildly). I did compare it to some dolby digital 5.1 tracks that are also on every blu-ray (the standard for DVD's) in a couple of movies I have (Apocalypto and Pirates: Black Pearl) and it is not a huge difference, but is noticeable. The differences I noticedare that it had a much cleaner bass feel for my subwoofer in a lot of instances, and it handles quiet and/or ambient sound much cleaner. Also, it seems to play louder at a lower volume level, so I'm not sure if that has any significant bearing.

However, the biggest difference is on Resistance. That game sounds incredible now. Unfortunately though, I can't switch between dolby digital and the PCM sound. But I can sy with great certainty, it's a whole new game to me now that I have a home theater set-up.

One more thing to add, optical can only output up to 2.1 PCM. For any more channels you need HDMI.

Really? It's 2.0 not 2.1

Really? I think someone needs to do research before posting.

Optical can only do up to two channels of uncompressed audio while HDMI can currently do 7.1. There is a GIGANTIC leap from compressed to uncompressed sound, and the price difference in receivers is easily worth it. I think my dog even notices when an uncompressed track is played vs a standard lossy compressed DD track. I have to assume you are only knocking it because you either can not afford it, or just are ignorant to anything dealing with current home theater setups. There is more than one game that supports LPCM after the latest update, and nearly every single blu-ray movie supports it. Why do people have this fetish of posting absolute inaccurate trash on these forums? They would do themselves more good if they ran out into oncoming traffic.

Optical uses compressed audio streams not uncompressed. To say optical can only output 2.1 PCM is clearly false that is all.

Optical can also handle 2 channel uncompressed tracks as well. So I have to think that the poster you criticized meant that optical can only do uncompress 2 channel pcm, which is true.

I have done countless hours of research before deciding to buy my latest receiver. All PCM soundtracks are UNCOMPRESSEDand sent via linear PCM. There is no such thing as an "LPCM" soundtrack. Everything I have stated is correct and you need to do your research.

You said optical can only do 2.1 PCM. Optical only has the bandwidth foruncompressed PCM at 2.1 which is never used.The only difference between the uncompressed and compressed PCMis the bitrate.Deihmos

There are quite a few SACDs that include 2 channel uncompressed tracks. Most people listen to music in stereo sound which makes for a great usage of optical. Optical actually has enough bandwidth to do 7 channel uncompressed sound, but due to industry standards it will never be utilized. Do you just randomly pull crap from nowhere just to be able to make a post?

You said optical can only do 2.1 PCM. You didn't say optical only has the bandwidth for uncompressed PCM at 2.1 which is never used. The only difference between the uncompressed and compressed PCM is the bitrate.

Optical passes dolby dital/DTS 5.1 sound.

Deihmos

There is no such thing as compressed PCM. I was incorrect in some regards, you can only do 2.0 PCM, but it is uncompressed. First you said there aren't any blu-ray movie titles out there. I gave you a list of 75. Then you said you can't do PCM through optical. I'm not sure if anyone uses it or not because anyone who knows about it probably has a better set up. That being said uncompressed PCM is possible through optical. You have adding nothing to this thread while I have provided sound information. If anything you are just confusing the thread creator.jshigashi

I never said there are no blu ray titles with PCM.My first reponse to the poster was to get a receiver with HDMi inputthis PCM compressed and uncompressed discussion erupted. Obviosly the higher bandwidth audio will sound better just like MP3 vs WAV.If you already have a receiver that does Dolby 5.1 is the upgrade worth it? If you don't have a receiver then might as well go for the best.

There is Dolby Digital 5.1 which passes through optical and PCM 5.1 which is a higher bitrate that needs an HDMI port. That is it.

EDIT: To the previos poster can you give an example of uncompressed PCM 2.1? I am sure it's 2.0. There is a difference between a discussion and a fight.

He may be just talking about PCM only being able to go 2.0 via optical (whereas I incorrectly said it can do 2.1). I have since retracted my statement if that's what he is talking about. If it is, I'd say that let's just end it at that. Sorry Deihmos :) That being said he makes a lot of other references that don't really make any sense to me.

Onkyo TX-SR605

can anyone throw in some more suggestions

I know this. I am almost sure thatall receivers thatdecodes dolby digitalwill accept PCM 2.0. Who would want to listen to PCM 2.0 though when there is Dolby 5.1. Unless you only have two speakers. Interesting discussion though.Deihmos

Well the two speakers being utilized for uncompressed 2.0 are going to sound a lot better than any of the two speakers in compressed lossy DD5.1. It really depends on the material.

I have the 605 and so far I love it. For me it came down to the Onk 605 and the Yamaha 661. Both are excellent receivers from what I've read. Another choice is the Sony 910. The cheapest one out there is the Panasonic 57.

Wow, now you see my confusion. I have an old Yamaha reciever that has no HDMI and I get no sound via the PS3 via fiber optic. So I am looking for a new reciever that supports the newest candy coming from these new blurays. So far the only reciever that I think that does this is the

Not meaning to hi-jack thread, but, would anyone think theres a big enough difference to warrant a purchase of a new receiver that has HDMI/multiPCM audiocapability. The one i have doesn't have HDMI.I'm using optical on it right now.

The new one would have similar watts, i have a 5.1 sound system. If you'd like to recommend a receiver feel free.

For me i would say no but i am sure others will say yes. It's like Audio CD VS MP3 Ripwhere there is a sound quality difference but for most people it's no big deal. In the end it's all up to you and if you are a major audio buff then go for it.

Yes it is a HTR-5730 it has fiber optic but that isnt carrying uncompressed audiogreater than 2.0. besides I really want to have HDMI and composite to component switching to clean things up. (wires)
