correction to that. It seems that you can find an option (after installin the latest realtek drivers) in the Windows control panel that says "Speaker fill". The description of it fits what I know as "speaker cloning". Just one thing: The Realtek drivers crash bloody often on Vista64. Rundll32 crashes for some reason.

I tend to agree, the realtek control panel looks plain ugly. Who designs those things anyway? Also, I can't seem to clone my channels for non-5.1 sources. I recall nvmixer being able to do that.

Any luck running NvMixer on Windows Vista yet? I can't get it working. NvAudioMod.dll is missing and when I copy it from my winxp installation, I cannot regsvr32 the dll - obviously because it wasn't designed for vista. I'd really love to use NvMixer because the standard Vista software won't let me clone my rear speakers. Thanks Sander
