What's a surround sound?


Surround sound is the main reason peoplepurchase themselves media centers. . Dolby Digital isthe common surround sound standard. The DVD manufacturers encode each DVD with5.1 channels of discrete Dolby Digital audio, which your receiver then decodes.The format creates a rich audio soundstage that brings movie soundtracks tolife with crisp dialogue, realistic-sounding special effects, and deep bass.

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

encoded with DTS Digital Surround. DTS Digital Surround (DTS) is another discrete multichannel
digital audio format available on CD and DVD software

Hi, I have a denon 2802 av receiver. My Dolby decoder seems broken, the doby-display-indiactor is blinking as soon as a dolby signal is receiced. resettting doesn't help. DTS is still working. Anaybody...


The processor that creates the surround is all on 1 chip so sounds like a software issue.

Call Denon to see if they have a firmware update for your unit this usually is free and may fix the problem

Surround sound for Blu Ray on older Sony receiver


Hello, it sounds to me like the receiver doesn't support the sound format being sent from the blu-ray player. This is because the blu-ray disc would have HD encoded sound such as DTS HD Master Audio or Dolby True HD. Most receivers have not been fitted with these sound formats untill quite recently. The reason for the menu sound playing correctly would be for the PCM (Pulse-code Modulation) which sends simple two channel digital sound supported by all digital receivers. It may be possible to use Dolby Pro Logic or similar formats to give a surround feel, but the only way to get true surround sound in this way would be decode the sound externally and input it through several phono cables into the multichannel input, however blu-ray sound comes in 7.1 so the receiver would need to be able to accept this to get the full effect. If it is possible, see if the blu-ray player will allow downsampling to a surround sound format that your receiver can accept such as Dolby Digital or DTS. Hope this helps.

Rear surround speakers quit working from my Onkyo


It looks like the audio output was changed on the player so that it doesn't output 5.1. Enter the setup menu on the player and change DTS to output DTS instead of what be labled as stereo or L/R and Dolby Digital to output Dolby Digital instead of whatever else it is set to.

Sound problem


Hi,

I have a creative SoundBlaster LIVE! 24 Bit External Sound Card and this annoyed me for weeks.

depending on your surround sound reciever depends on the solution.

i have an Acoustic Solutions surround sound system with coxial and optical inputs, aswell as stereo red & white jack inputs.

not knowing the method or connection your using makes it difficult to give you a single solution so i'll list a few.

The soundblaster software shoudl include the Creative Audio console with all sorts of effects, one is CMSS (CMSS-3D) Stereo widening which is still stereo but gives a surround sound effect.. but i'm guessing you payed for 5.1 and you want 5.1 onto the next part

5.1 surround sound can only be produced when the actuall audio your playing contains 5 channels of audio, for example you cant play a stereo song in 5.1 surround sound without some sort of hardware or software sound manipulation. Luckily my surround sound system has Pro Logic II built in and some other effects which convert a 2.1 signal to a 5.1 signal and it works brilliantly. I'm not sure of a software alternative.

setup for your soundcard will be different under XP and Vista also, but there should be a properties option for your sound device where you can select your speaker setup such as headphones, built in speakers, 2.1 speakers, 5.1 speakers, 7.1 speakers and you should be able to manage this from the creative software.

If using Coxial / Optical or SPDIF under vista you MUST set the playback device as SPDIF, at least you have to with my sound card and drivers and seems to be a limitation of the actual sound card drivers for vista.

Personally i was looking forward to hearing the windows login melody in 5.1 surround sound too, but this doesnt happen.

Infact i find that almost all programs bar a few will not play Dolby Digital or DTS 5.1 surround sound via any or my output options hence the next solution..

if you have the 5.1 sound but winamp simply just plays it in stereo try the following.

You need to use DirectSound Output:

Preferences (Ctrl-P) > Plug-ins > Output > Select "DirectSound Output"

That should work in most cases, but if not, then:

Checkmark: "Allow hardware acceleration" in DirectSound Output config,
and make sure your sound card/chip is selected as Output Device.

Note that any changes will take effect only after playback is restarted.
In some cases, a Winamp restart is required.

If that doesn't work make sure you have the latest version of DirectX
(v8.x or higher is required)

Winamp 5.25/5.3 and higher:
For actual multi-channel files (ie. aac/wav/ac3/ogg/wma files encoded in 5.1ch surround, as opposed to standard 2-channel stereo mp3's), you need to checkmark "Allow surround sound" in 'Winamp > Prefs > Playback' for the music to play in its original 5.1 channel format (Note that this setting is checkmarked by default).

Windows Vista:
In addition to the above instructions, Vista users will also need to go to:
Control Panel > Sound > Playback tab > Speakers > Configure:
Select: 5.1/7.1 Surround.
Then:
Control Panel > Sound > Playback tab > Speakers > Properties > Enhancements tab
and checkmark "Speaker Fill"

Hope this helps
