Is it possible to have some sort of 5ch stereo?

My denon avr3802 has a mode of 5ch stereo, which i REALLY love....

i am wondering if there is a way, driver and what not, that this could be accomplished... I have an nf680i with the internal audio.

i have checked the speaker fill but it does little.

What i want is to hear the same out of my front speakers than my back speakers and have a "surround" sound but that is stereo. Or that you hear the dialog out of the back speakers also....

Hope i made myself clear.

Thanks

Depends which music software and hardware you are using as to what you hear really. I use foobar2000 and the kernel streaming plugin. That puts out music to all my 7.1 speakers via digital or normal ouput. ASIO plugin will also do the same thing.
I think that Winamp will do the same, but I don't really use it so cannot comment much on that.
Windows media player is useless with no decent plugins, so don't even try that one!

would those plugins work with windows media player and/or media center?

Thanks

No mate. As I said, WMP is useless for the type of playback you require.
