I am currently using foobar2000 which has the ability to "Convert Stereo to 4 Channels" by simply duplicating the Front Speakers output to the Rear Speakers.
This Sounds really great opposed to the "Speaker Fill" Option in my Realtek HD driver, which only seems to copy certain frequences (e.g. no voice) to the Rear Speakers. This sounds horrible.
What i want is to have the foobar2000 thing for all my application when there is no 5.1 sound available.
Is there a software that can archieve this in Windows 8 x64?
