I have set the same settings, of course that didn't solve my problem.
On XP, even now, I still use SRS Audio Sandbox, probably one of the most powerful drivers, to alter Surround Sound, Stereo sound, Quadraphonic - etc. by adjusting sliders. I can choose the stereo 'size', the center 'location', to enhance my sound experience, and the sliders for Surround work perfectly fine on windows XP with the exact same driver setup - no matter what sound device was actually connected, may it be stereo speakers or headphones in the front jack. However.
On Windows 7, I used your settings (though I already had them like that) and used the preview option to preview the sound. (pre'hear'). But I only get sound from the front speakers. For me, this is a general problem, it's not just a difference between driver testing and actual use by sound applications, even the test returns negative results for me.
Since apparently this works, I can not confirm this, it means that somewhere in the updated code from above, a solution may lie for realtek. Is the plugin open source? And if so, maybe it can be used by realtek, or just hackers for all we care, to update the driver software from realtek either officially or manually to fully support surround, even when using headphones and such?
