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. This means that if you set it to 5. MB, the rear speakers will not be getting any sound.

DVDBlu Ray movies attempt to play true 7. Problem 2 The Realtek HD drivers for Windows 7 do not currently appear to offer a stereo upmix feature, which is what allows 2 channel stereo to be played back on more than two speakers. So even if the rear speakers are recognized in the test utility, when you play normal stereo audio sources, sound will only come out of the front left and front right speakers unless you use a program that has its own upmix functionality. This seems likely to be a bug some of their earlier drivers offered this, and the drivers offer many othermodes that upmix and modify stereo audio output, just not a simple surround upmix. To fix this Ideally, Realtek should add back in the surround fill option that was there in some of their other non Win. If that option is there, just check it and you should be set.

R2. 5. 0 do not have this option, at least in Windows 7 6. If that option is not there They ohave another mode that will do this, but it may slightly affect the sound output. If you go under the Sound Effects tab in the audio manager, changing the Environment setting to Room will effectively cause a stereo surround upmix. All of the modes will do a stereo upmix, but most of the other ones apply various effects that will make your music sound terrible. This one is close to neutral. Another option if your motherboards chipset supports it is to use Dolby upmixing. This lsomay slightly affect the sound quality, although probably less than using their effects panel. To do this, go to Control Panel Sound, select the Speakers output device, and hit the Properties button. This should open up a tabbed window with a bunch of settings. If you have a Dolby tab, go to it and check the Dolby Prologic IIx checkbox or whatever option is there. This will remix stereo sound into 5. If there is no Dolby tab, then your motherboard does not support Dolby upmixing. Another possible solution is to set all the jacks where your speakers are plugged in to Front Speaker Output. This will cause the driver to send the same 2 channel output to all the speakers.
