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.

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. However, this will break anything that tries to play real 5. Realtek also offers a utility on their website called 3. D Soundback. This may be helpful, although it has to be configured on a per application basis. It is also designed for Windows Vista, so it may not work properly under Win.
