Hello Everyone, I have just recently upgraded from Windows XP 32bit to Windows 7 64bit, I am now receiving this problem as i notice many others have gotten also. Previously my sound was working perfectly although when i downloaded the Windows 7 64bit Version of Realtec Audio Driver/Manager the whole interface was new, and when i run the Speaker Test it outputs sound in all speakers, But when i try play music/games the sound is only 2.1, I have managed to get sound on the rear / center speakers but only on poor quality by setting unwanted settings, Such as Sound Environment, Speaker Fill etc. I am running driver version '6.0.1.5485', I have noticed people on Win XP just reverting to an older driver version. I don't think that is quite possible for Win 7, Has anyone solved the problem on Vista/Windows 7? Rhinoceros 5 Beta Keygenguru.

All feedback/help would be greatly appreciated, Future. Future, Go to device manager, click on the audio device in question, select the 'properties' option. Fromt here click on the 'driver' tab, you will have an option then to 'roll back driver' -- if that option is selected it should revert back to the driver installed when first configured. For further support, Microsoft does have an official Windows 7 RC Support Forum located here. It is supported by product specialists as well as engineers and support teams. Jessica Microsoft Windows Client Team. I have the same problem as Future.

I have a creative sound card and 5.1 logitech which worked brilliantly in windows xp but since I upgraded to windows 7 my sounds playback is really dodgy. The sound first of all sounds choppy especially when I'm doing smething in the background and I got 4 gig ram so I don't think that is the problem. I've tried every concievable thing to try and change the sound settings so it supports all 5 speakers but only the 2 front ones play.

When I run a test all the speakers work but during playback only two work. What do I do. Revert back to xp but loose the brilliant new features of windows 7?

Yep, another one here - seems common. All drivers up to date (tried various!), all settings to 5.1, test works fine in Windows AND Realtek Sound Manager but no apps want to play anything except stereo. Can't find a fix anywhere and I've literally spent 2 days on it. Guess may have to await a driver fix unless anyone has any other ideas?

Add me to the list of people with this problem. I just upgraded to windows 7 and now 5.1 audio using SPDIF won't work. I don't even have the option to set the number of speakers I'm using. When i go into sound properties, then advanced, I can only select 2 channel operation. I've got a gigabyte board with Realtek HD audio. After a week searching for a definitive solution, just like most everyone, I was forced to give up trying to find a way to make Windows 7 send music to all speakers with same quality. And since I'm not willing to pay $30 for Creative software (see: I guess I'll have to wait for Realtek to provide a solution, as its 3DSoundBack, which is supposed to do the same as Creative's ALchemy, did not solve the problem either.

The adaptive dynamic section includes an expander and upward compressor. With the optional Upmix license, the unit can be set to detect stereo only content and automatically upmix to 5.1 in order to maintain a constant surround experience. Existing 5.1 content will pass untouched. C8092 Level Magic™ processor / 5.1.

The only workaround I've found was in this post: Neilsouth explains how to change Realtek output assignments through the registry. I've found a solution!!! It seems I was wrong about 3D SoundBack! It really does the job! I thought it didn't work because when I clicked it nothing happened. Only after searching through a few sites again I saw a screenshot of it running and realized it was designed to Windows Vista, so all I had to do was run it in compatibilty mode for Windows Vista Service Pack 2, add the applications and voila!

I got surround sound again without registry tweaks! Download 3D SoundBack Beta 0.1 from Realtek Website I've tested it with some programs, it worked with Winamp, MediaMonkey, BSPlayer and PowerDVD. Couldn't get it to work with Windows MediaPlayer though.

The software is designed for games foremost, so it should work with them as well. There's just one problem when running MediaMonkey: in my PC it will crash if I have QuickTime installed, haven't figured out why. I'd like to know if anyone has a solution for the QuickTime issue or get WMP to work as well. Add me to the list of people with this problem. I just upgraded to windows 7 and now 5.1 audio using SPDIF won't work.
