Dolby surround, Dolby Digital Surround problems

When playing cd, direct tv source in window says pro logic , however i seem to get all sound information thru center channel only.  As a full mono speaker.With DVD in Dolby Digital same problem.  Full sound thru center channel.  DSP will move sound to other speakers, but with no effects on just center.  Also when I bring on white noiswe speaker test on screen, shows only center speaker delivering white noise. As speakers blink on graphic, the others remain quiet, no white noise.  Do I have a problem with the processor in the receiver, or am i doing something wrong here?

SOURCE: DTS Master HD audio problem

Hey! Make shure your amp and blu-ray player output and input signals are set to "bitsteam" and you are useing HDMI and optical connections. I hooked up my Onkyo tx sr 506 integrated amp to a Samsung BD 1400 player and everthing worked perfectly right out of the box. Perhaps your amp can"t decode DTS HD Master or your blue ray doesn't support it although i think a firmware upgrade may accomplish this. Put on The Chronicles of Narnia Prince Caspian which will DEFAULT to DTS HD MASTER 7.1 and see if it works. It's an excellent source to test your system. Picture and audio recieved 5 stars from Home Theatre magaziene and like i said, either your amp, or player doesn't support it or your interconnects are keeping it from coming thru. HDMI and OPTICAL connects and check your set up for "bitstream" Remember what Todd Rundgren allways said,"Everything will work if you just let it!"

SOURCE: Hi, I have a Yamaha DSP-Z9 amp. The amp runs

Hissing or high-level digital hash noise? Undecoded DTS or data bitstreams produce very loud 'rush' sound when treated as analog sources. Is it all sources or just some?

As far as service manuals go, web search it "Yamaha DSP-Z9 service manual" - many for sale.

How do I get the C5 Subwoofer to activate?


Hello
If subwoofer is inactive now, the sound preference settings you set now is wrong.

Before using the remote control for the following
operation
* Set the remote control mode selector to AUDIO

** There are exceptions in the operation mentioned
above. In such a case, follow each instruction

Dolby Pro Logic II*1

# Dolby Pro Logic II has a newly developed multichannel playback

format to decode all 2 channel sources - stereo source and Dolby

Surround encoded source - into a 5.1 channel.

Dolby Pro Logic II has two modes - Movie mode and Music
mode

# Pro Logic II Movie (MOVIE)
Suitable for reproduction of Dolby Surround encoded sources

# Pro Logic II Music (MUSIC)
Suitable for reproduction of any 2 channel stereo music sources

# Dolby Digital*1

Used to reproduce multichannel soundtracks of the software
encoded with Dolby Digital

# DTS Digital Surround*2

Used to reproduce multichannel soundtracks of the software

We hooked it up and have no sound


From the Console Settings screen in the System area of the Xbox Dashboard, you can configure the video output of your Xbox 360 console for a widescreen, high-definition TV, determine your audio options, and check your console's serial number and Xbox Dashboard version.
Go to correct section for ... Audio

Change your audio output settings for games from this screen. These audio settings do not affect DVD movie playback. For DVD audio settings, refer to an individual DVD movie's setup screen.

Settings consist of:

  • Analog Output Settings: choose Mono to merge the left and right audio signals so that you can hear all sound through a connection to a monaural TV or monitor; choose Dolby Pro Logic II to listen in normal stereo (no audio surround receiver required) or to listen to Dolby Pro Logic or Dolby Pro Logic II soundtracks from compatible games or other media.

    Dolby Pro Logic consists of four channels of audio: front left/center/right and a monaural surround channel that is mirrored in each of your rear left/right speakers. Dolby Pro Logic II uses digital signal processing to generate 5.0 audio (front left/center/right, rear left/right) from any stereo (left/right) programming, whether from movies, music, or games. Unlike movies and music, however, games are specially encoded with Dolby Pro Logic II decoding in mind.

    To listen in either Dolby Pro Logic or Dolby Pro Logic II surround sound, you must connect your cable's left/right (white/red) RCA connectors to a compatible surround receiver. For more information, see our connection page for the cable you're using:
  • Digital Output Settings: configure this setting only if you'll be using the Toslink optical digital-audio output from a compatible Xbox 360 AV cable (optical digital-audio cable sold separately):


    The default digital-audio setting is Dolby Digital 5.1. If this is your preference, you do not have to make a selection from this screen.

The audio keeps going in and out and cuts off. Also I have other devices going into aux in but it doesn't show 5.1 surround it only shows the front L, Front R, and CT speakers in stereo. I want everything...


If you are playing a source that is Stereo such as FM Radio or a CD the sound will not use all 5.1 speakers unless you enable the correct Surround Mode. On the remote there is a button on the lower right of the remote that says SURROUND. You can toggle through the various surround modes with this button the mode you want is Dolby Pro Logic The Pro Logic mode uses the built-in circuit to steer the Left, Center, Right and Mono Surround channel audio signals and uses all five speakers to play both stereo and Dolby Pro Logic program source, such as TV and VCR. You can use this mode with any stereo program source (such as VCR/TV) to enjoy multi-channel sound experience.

I'm going to surround sound mode, and my rear speakers are not working. I do a tone test, and they def work, but I can't get them working right?


Since you seem to be having problems with 'simulated' surround, how does ACTUAL surround material behave?

Have you tried AFD with certifiable multichannel source material to verify the surround speakers receive programmed sound??

Do the Dolby Digital or Pro Logic indicators light?

What about the other modes?

I have a new rca receiver and have it hooked up to my dvd player which works fine. I have it hooked into my tv and Im not getting sesurround through my tv how can I connect to the tv to make it work my tv...


Take a clue from the 10-year old vintage of the TV and the two analog audio cables. It's Dolby Pro Logic Surround at best, not Dolby Surround in the modern, digital, multi-channel sense.

TV's are not the source nor the end of a multi-channel audio chain. Feed this thing a 2-channel source from a Cable Box (into the "TV" jacks), DVD, Video Tape or CD with proper Dolby Surround encoding and will seem to open up the sound field a bit and kick in a little surround effect. It can also simulate a Hall effect and Dolby 3 stereo.

Lg home theater to lg plasma tv


This is a typical problem with TV broadcast UNLESS you use a matrix DSP surround sound mode, most DVD audio is either Dolby digital 5.1 surround or DTS multi-channel surround sound, unless you are viewing a HDTV broadcast with 5.1 Digital sound connected from the TV to the receiver then you are probably receiving a 2 channel Stereo sound format, I would suggest that you try to set your TV input mode to a audio Dolby Pro- Logic which will yield 5.1 and should engage all speakers.

The indicator is telling you you have a 2-channel input. You may have the Blu-Ray connected wrong. Or the source is only Stereo. I need more details to assess that.

The sound coming from all speakers is normal if you have any surround mode selected, regardless of the characteristics of the source

I imagine if you experiment you might find all speakers playing for any number of 2-channel sources, not just Blu-Ray. Besides actual Pro Logic decoding, the various surround modes can provide some interesting effects on non Dolby Surround material.

I recommend that you try them all on various recordings and you may find one or another of them preferable over vanilla stereo. I find that any given artist or music type, even within a given CD, may sound 'better' with different surround settings.
