Your source will determine the Dolby Digital capabilities. WHAT is on video 1 and is it Dolby Digital?

Rear speakers only work during calibration and testing. Not during playback.


This commonly happens based on the source. For example, if your receiver looks at the source that is analog, it will use two channels, the two front left and right speakers. However, some receivers, such as a Denon, have a 5 channel stereo feature that will utilize all 5 speakers (L&R Front, Center, L&R Rear). If you are connecting a DVD player, often you need to configure the source appropriately. If you are connecting using the RCA cables, it will be stereo. If you are using Optical or Coaxial connection, you can enjoy Dolby Digital, but may need to specify in the receivers setup to use these audio source inputs. If you are connecting via HDMI, early versions only supported Dolby Prologic, but you occasionally hear mono sound from rear speakers. Without knowing more about your equipment, what source you are hoping to hear and how you are connected, it will be difficult to pinpoint your cause, but hopefully this helps your understanding to enable you look for the appropriate cause.

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.

Bought a LG Blu ray DVD Home theater system last weekend and set up with LG lcd tv and has been working fine till today. We had the radio on and I turned the TV on and the two rear speakers do not work...


Hello,
In a surround sound system, the correct way to listen to music is in stereo mode which will play out of your left and right channels and your subwoofer. When viewing a movie with surround sound, then you should use your rear speakers. The key element to remember is that rear speakers are only intended to play your sound effects, and will not play full range audio. Thats what your fronts and center are for. If you simply want to override this, than you will need to select the direct sound field on your receiver and than it will send full range audio to all speakers connected. Most likely, its not going to sound that good. If you dont know what each sound field does, here is a list and function of the most commonly used ones.
Stereo-Front Left and Right speakers including subwoofer
Dolby Digital or PLII Movie-these are the bost options for your surround sound
Direct-All speakers connected get full range signal
Good Luck

When I plug every thing in we only get full sound out of 2 of the speakers


Go to the sound test/speaker setup page, this will produce a sound out of each speaker one after the other, it will confirm that all speakers are correctly connected.

Depending on what you are playing through the unit the audio track may only be in stereo, which may explain why only 2 speakers are used.

You require an audio track in Dolby Surround/Dolby Digital etc for multiple speaker output

There is no Sound on the surround chanels (rear left and right) at Dolby Digital Mode. What is the problem?


I'm having trouble finding the manual but you can't just attach speakers and expect them to work. You need to find the SYSTEM SETUP and perform the Speaker Configuration first and define the Surround Speakers. It probably says NONE right now.

Dolby digital


Dolby Digital includes several similar technologies, which include Dolby Digital, Dolby Digital EX, Dolby Digital Live, Dolby Digital Surround EX, Dolby Digital Plus, and Dolby TrueHD.

Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center, left front, right rear and left rear) and one channel (20 Hz – 120 Hz allotted audio) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48 kHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The Laserdisc version of Clear and Present Danger featured the first Home theater Dolby Digital mix in 1995.

This codec has several aliases, which are different names for the same codec:

* Dolby Digital (promotional name, not accepted by the ATSC)
* DD (an abbreviation of above, often combined with channel count: DD 5.1)
* Dolby Surround AC-3 Digital (second promotional name, as seen on early film releases and on home audio equipment until about 1995/1996)
* Dolby Stereo Digital (first promotional name, as seen on early releases, also seen on True Lies LaserDisc)
* Dolby SR-Digital (when the recording incorporates a Dolby SR-format recording for compatibility)
* SR-D (an abbreviation of above)
* Audio Coding 3 (relates to the bitstream format of Dolby Digital)
* AC-3 (an abbreviation of above)
* Audio Codec 3, Advanced Codec 3, Acoustic Coder 3 (These are backronyms. However, Adaptive Transform Acoustic Coding 3, or ATRAC3, is a separate format developed by Sony)
* ATSC A/52 (name of the standard, current version is A/52 Rev. B)

Audio receiver!


When I watch movies, most of the talking is directed to the center speaker. During surround sound, this gives a more realistic environment, with voices coming from the source (center where your tv is) and ambeint noise coming from the left/right corners.

Get a small center speaker to solve your problem.

Back speaker sound


Why would you only hook up one speaker for the rear channel? in 7 channel stereo, all speakers have 100% signal sent to them as "stereo" in Dolby digital, rear speakers are for "effects" not dialog. like a plane flying past you or a car driving by, that's when you hear a rear speaker. It also needs to be placed behind you, not next to you or in front of you. Unless you are using zone 2 & 3 the receiver's surround back will work. if you only have left,right,center,sub & rear; the rear speakers should go to surround speakers not surround back. If you still have questions, post a comment and I can explain further. Hope this helps
