Windows 7: Windows 7 5.1 surround problems (realtek)

18 May 2011   #261

Windows 7 Ultimate x64
 
 

Sorry for digging up an old post..

but i had the same issues for ages, i recently just upgraded my computer and had the same problems, however as i plugged each cable in i got a pop to confirm what i had just plugged in, choosing rear speakers never worked.

However i then took it out, plugged it back in and chose 'headphones' with the sub/centre and front both configured to their own options.. and i now have all 5 speakers working together

Windows 7 32bit
 
 

Hello guys! first im sorry to bump this cuz i hoped this will be fixed by now...

Yes i have the exact same problem. 5.1 works in games and when testing the speakers in realtek manager, and in built-in sound manager from windows 7.

But when i play music or watching a movie it doesnt work. It should have worked NATIVE as it did in win XP. Flawlessly!!

Now my advices to make it work better are :

In certain games where 5.1 doesnt work, try this software from realtek called 3DSoundBack_Beta0.1.rar


MEGAUPLOAD - The leading online storage and file delivery service


1.


2.


3.


Then press the enable button and now your gave should have 5.1 sound.
========================================================

Now for movies, for example opened with BS Player. Get ffdshow from HERE
(direct link)

And open audio decoder and configure it this way
1.



2. This one you can put it on Doubly Surround or ProLogic if you want too. It's pretty much the same. Worth checking them.



Now you should have 5.1 sound enabled in BS Player. As for Winamp, other solution than selecting Room enviroment from Realtek manager, i dont know. Hope this helps.

It's a bit better for me now. I still cant believe an issues which dates since Windows 7 released, still hasnt been fixed by Microsoft or Realtek. Last time i buy Gigabyte mobo with Realtek anyways...

First of all, forgive any english mistakes. It is not my primary language.

Notice: Some options may not have exactly the same description shown here. Please use common sense to figure out wich option to choose based on the information contained in this text.

I've consulted many forum posts around the world about making a 5.1 usb sound card output 5.1 sound through spdif(optical) on windows 7 (Windows 7) and found very little information about it.

After two long days of trial and error, I've finally made it work. So here is the full story/process:

I've bought a sound card like this one:
Premium USB 2.0 External Sound Card Box with 7.1-Speaker SPDIF Optical Output - Free Shipping - DealExtreme

And connected it through optical spdif to a 5.1 samsung home theater.

The first step was to download this driver for the cm106 chip:
Download C-Media CM-106 Windows 7 Driver v.6.12.8.2131 | CM-106 | Catalog - News, articles, free drivers and firmware catalog: X-DRIVERS.COM

Once installed the driver and the sound card connected, it will show a systray icon that when double clicked opens an interface for configuring the sound input and output for the card. The options that worked were 8 channel for input and 8 channel for output. The interface will display 8 speakers (front left and right, center, middle left and right, back left and right and lfe/subwoofer).

On windows settings for the device (displayed when you right click on the speaker icon on systray and select "show audio devices"), there is a tab for "supported formats" shown after clicking on "properties" for the "digital/optical output usb device", I've unmarked everything but "dolby surround". Right beside it there is a button for testing the sound card configuration, click it and you should hear a sound that will start on the lfe/subwoofer and will play around each speaker in sequence, separatedly.

The tricky part was to play correctly ac3 and dts encoded audio from movies on my preferred media player: kmplayer.

On kmplayer, at first I needed to go on options and turn off every internal codec and make kmplayer use external codecs for audio. I then chose ffdshow for audio decompression. (Other media players like media player classic (home cinema or not) already use external codecs by default).

The key change was to configure the output on ffdshow. For my sound card and home theater configuration, on "Output format for uncompressed or decoded streams" box I've checked "AC3 (s/pdif encode mode)" and "encode 5.1 streams only". And selected only "Dolby Digital (AC3)" on the "Pass through" box.

The ffdshow screen for making these changes is this one: http://www.homecinema-hd.com/images/.../ffdshow13.png
ATTENTION!!!: The screen from the link above DOES NOT reflect the marked/unmarked boxes that were chosen. It is for reference only!

After doing this, ac3 and dts audio encoded from avi and mkv files worked perfectly on the 5.1 home theater system.

Hope it can help someone!

If you have any doubt or trouble, feel free to contact me at www.lantis at gmail dot com. (and yes, it CONTAINS the www, lol)

Executable for switching betweed 5.1 in C# and .NET4

It is for win 7 x64, i am too bored to make it dynamic also for x32


This program will do the same thing as the batch files, but with some additions together with visual window:

* Run it and it will enable 5.1 sound. Run it again and it will go back to 2.1 sound.
* Will rename properly MP3DMOD.DLL
* Will fix WMP not displaying an error if closed by taskkill.exe via registry keys under key "HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Health"
* Will make plugin wmpkeys run again properly under registry key Running in "HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\UIPlugins\{9B61F641-7794-4322-BF6A-E45EFD6C8D7C}"
* Will start media player in library mode.

Ok that's all, have fun, download link at bottom.
