Official Blu-Ray Player Audio Setup Thread - All Audio Questions Go Here - Page 47

Thanks, I saw that. My player is a newer version and does not contain that warning. Very odd that Panny should set it up that way.

I have no sound from my subwoofer with blu-ray discs in my new Sony BDP-S570 and I'm hoping someone can guide me to the right setting.

Blu-Ray player: Sony BDP-S570 with latest firmware
Reciever is an older Onkyo HT-R510

Audio is connected via Digital Optical (no HDMI with this receiver)
Running a 5.1 setup

Blu-Ray Audio Settings are:
BD Audio Mix: on
Dolby Digial Coaxil/Opital: Dolby Digital
DTS (Coaxil/Optial): DTS
DTS: On
Audio DRC: Auto
Downmix: Srround

When I run the audio optimizer with the Standard Def DVDs of Toy Story 2 and UP, the sub comes through loud and clear (no sound comes out of the center surroudn speaker, as there is none).

When I run the blu-ray versions of the audio optimizer on those same two movies, I get no sub. However, when the "center rear" test runs, sound comes out of both left and right surround speakers for some reason.

Any ideas? Thanks for the help!

I suspect the problem is with the test track on the discs. Your sub obviously works with the other test tracks. Does your sub work when you play Blu-ray movies?

It's correct for the rear channel on a 6.1 source to show up in the surround channels. The rear channel is down mixed into the surrounds when the system is configured for 5.1. That way you don't miss anything.

I think you might be right about those discs. That's terrible that Disney would screw up the optimizers.

Looking for someone to sanity-check my understanding of audio options for my current setup
I have just hooked up a Panasonic BDT110 BD player to a Panasonic XR57 receiver with a 6.1 speaker setup. Here's the restrictions

1) Due to known LFE bug on that receiver, there's no good value in sending PCM over HDMI.
2) Since receiver is only HDMI 1.2 (and without Dolby HD or DTS-MA decoders), I can send bitstream over HDMI, but only DD or DTS standard would actually get sent / processed.
3) Since optical PCM only supports 2.0, no reason to use for a 6.1 setup.

With the above restrictions, I've accepted that with this receiver I'll never get lossless audio. So this leaves me with decision of accepting bitstream over HDMI or optical? Between those two choices, is there still a benefit to HDMI due to different bitrates? Does either conncetion lead to a better 6.1 solution for the occasional disk that has rear tracks encoded?

Eric

No difference. The lossy codec bitstreams will be the same over HDMI and optical. They'll also sound excellent, perhaps just as good as lossless. The lossy codecs are less compressed on Blu-ray than they are on DVD.

Hey guys,

I just got a new "Sony S580" and have some questions about the surround sound playpack. I have the Blue ray player hooked up via HDMI to my Denon 3311CI reciever and it puts the surround mode in "DTS-HD-MSTR" and I would like "Dolby digital" unless you guess think the DTS is better LOL!! The Movie I am playing/watching is "Tron" and it says it supports both modes.....How do i get it to play in "Dolby digital"??? I will admit that the "DTS-HD-MSTR does sound good but would like to compare them or see what the difference is.

Thanks!!

as dts-ma is "lossless", and dd is "lossy", you are getting the "better" one now...

however, if you want to change it, you do it through the disk menu, not through the player... go to the "audio" in the disk menu (or whatever they call it on that disk), and change it there...

The encoding format is set when the disc is authored. It is not something that can be changed in the receiver. Very few BDs offer both DTS and Dolby choices. You get one or the other, not both. I do not recall that either Tron or Legacy has both dts-MA and TrueHD. If a disc has both, you would make the selection on the disc audio menu.

As for differences, with lossless there is none. There can't be. Lossless means the PCM that comes out of the decoder is identical to the PCM that was fed into it. When the same source is used, the decoded outputs of dts-MA and TrueHD must be the same.

My Blue ray has a choice of dolby digital but my reciever or mayby the player sets it is DTS. When I first hooked it up it was only playing in multi-channel stereo, I had to disabel the downmixing option to get what I have now. The previews were in Dolby digital and when the movie started it switched to DTS-HD-MSTR.

You should think of DTS and Dolby codecs as types of zip files. The person doing the encoding decides which type to use. You have to use the corresponding decoder in order to get sound out of your receiver. So, if the track was encoded using DTS, you must use a DTS decoder. Fortunately, receivers are smart enough to detect the type of encoding that was used and they choose the appropriate decoder without any intervention by the end user.

"Multichannel stereo"? Once a track has been decoded, you can force stereo downmixing on most receivers. But that's something different than decoding.

Most Blu-rays use DD 5.1 or PCM for the previews and dts-MA for the movie itself.

Ok so please someone set me straight on this cuz I'm not 100% sure...if your bluray player internally decodes Dolby HD/DTS HD..does that mean that my receiver does not need to have the capability to decode these two sources? Or to get the true benefit my bluray player and receiver must be able to decode?

One of them has to do the decoding, it makes no difference which. None, nada.

Internal player decoding means your AVR does not have to have the decoding capability. It must be capable of handling the decoded audio from the player though. This is most often by analog hookup.

Got it..either one via HDMI..thanks guys!

Well, I am screwed temporarily. My JVX RX-6030V has no HDMI inputs/outputs (it was made in 2004) just a digital coax and a optical audio input. I usually just do primary pass through on my LG BD630 bluray player, but menu audio on blurays doesn't get passed (as the owners manual says), and naturally, PCM Multi channel just gets 2 channels. I could do DTS reencode, but I'd rather not with this old AV receiver (because I prefer DTS to be DTS and DD to be DD).

ok i just bought a oppo 95 and i have a pioneer elite sc-07 i will be using hdmi for picture and audioquiest king cobras for audio and ideas how i should set my oppo.. i have a 5.1 system im using speakercraft aim8 fives and a valy minivee


thanks

The manual has recommended settings for all sorts of configurations. It is, unusually, helpful.

I use a Panasonic BD60 blu-ray player. My Onkyo 674 receiver does not decode TrueHD or DTS-HD, therefore I have the bd player do it and send it multi-channel pcm. When I play a movie that has TrueHD the player always defaults to decoding Dolby Digital. I have to hit the audio button at the start of the movie to switch to TrueHD. Are there any blu-ray players that allow you to prioritise what audio is decoded by default? It would be nice to put in a blu-ray and always have DTS-HD and TrueHD and the default sound that is decoded so I don't have to hit buttons when the movie starts.

Ensure that you have BD-Video Secondary Audio set to Off. That's under Setup, Audio, Digital Audio Output.

i know the manual is very helpfull but was not looking for that as an answer thought someone might have some other insight....

No. The default track is set when the disc is authored.

You must be watching a lot of older Warner Bros. releases. The lossless track is set as the default by most studios. WB used to set DD 5.1 as the default. But, they've switched to using TrueHD as the default now, too.

I am a little confused. I had my LG BD590 set to HDMI DTS recode. When I played a disk my AVR came up indicating DTS and when streaming from Netflix the Denon AVR 2309 CI indicated "Sterio". So I switched the Audio on the LG to HDMI primary pass thru and set the AVR to Cinema mode, when playing Netflix streaming I see the AVR is switched to Dolby PLII 5.1 and when playing a blue ray disk "Traitor" the AVR indicated Dolby Tru HD 5.1. When I looked at the audio setup on the disk Dolby Tru HD 5.1 was the setup. There is no direction as to what sampling frequency the LG should be set up. There are 3 choices but what do I select?

DTS Re-encode tells your player to decode the lossless track and then to re-encode it as lossy DTS. Not optimal. Stereo sources are simply passed as stereo regardless of the re-encode setting.


Primary Pass-through is the way to go for lossless audio. NOTE: Setting the player to PCM would also give you lossless along with secondary audio (menu clicks and PIP commentaries). Using Cinema mode tells the AVR to apply a DSP such as PLII to stereo sources.


When bitstreaming, the sampling rate doesn't come into play. The LG simply sends whatever is on the disc. Sampling rates come into play when sending PCM. Set it to the highest level your AVR supports.

Ok I will set the sampling at 192khz as it works fine on all three with my AVR.

You mention that most blu ray disk come as DTS and as I mentioned everything I have watched on disk hha been DTS so I thought I did something when "Traitor" came up on the display of the AVR as Dolby Tru HD 5.1. Although my AVR is capable of 7-1 I have it set up as 5-1 because my TV room is only 12X12 and I have a 60" TV (football) which is good for flix also

I always thought DTS was the better codec (directly off the disc - not referring to re-encodes)

Some people prefer DTS, although I doubt they could tell the difference in a blind test. But, with lossless audio, there is no difference between dts-MA and TrueHD. They both produce identical PCM when decoded.

Hooking up a panasonic blu ray to a yamaha reciever with only 2 speakers.

I have a couple of questions:

First, it offers bitstream or PCM output. Which one? I assume I want the reciever to do the processing?

Second, I have turned all the speakers off in the reciever (except the two fronts), do I need to turn anything off in the panasonic blu ray?

I have the speakers set to large, everything else is off. The receiver can do all the HD audio formats.

I am using HDMI.

It doesn't matter. The receiver does the processing either way. With PCM, the player does the decoding, and perhaps the downmix to stereo, but there's not much to those tasks. Everything else happens in the AVR either way.


No. With digital, none of the player speaker settings come into play. The AVR settings get used.

AVR is Pio 9040.Using BSG as source on Netflix.Hooked up from PS3 to avr using hdmi.No matter what settings I use can only get stereo-no 5.1.In a different part of the forum they suggested I come here.Below are some replies I got.
''many pioneer receivers from 2009 and 2010 have a bug in the dd+ decoding that force a downmix from a source delivering dd+ to stereo (or, alternatively, not working at all)...

that sounds like what is happening to you...

a workaround (assuming the ps3 will support it from the netflix app)... have the ps3 decode the audio to pcm for the netflix app and send it that way... the ps3 should decode the dd+ properly, and at that point, the avr no longer cares about the codec, all it sees is pcm...''
''next, i'd ensure that there is no downmixing going on in the ps3...''

Can you tell me how to check for downmixing on the PS3?
Thanks
y'know... i don't remember... it's been awhile since i've used my ps3... check in the dedicated ps3 thread in the blu-ray player section... those guys should be able to help you...
Thanks
