This is probably better on the LAU list.

Some cheap soundcards will copy a stereo stream over front and rear 
giving the impression of surround sound.

However I have a cheap cmipci < $10 which has two seperate devices nodes 
for front and rear and you could use each side of the stereo channel as 
a mono if neccessary. Not quite the same amount of control as the pro 
cards though. Concievably, with an appropriate .asoundrc multi device I 
could run jackd in playback only mode then  access the front and rear at 
the same time through any jacked app.

I use the multi device so I can access all four channels on my quattro 
but haven't tried to use it with the cmipci as I don't make music with it.

Being on stage with the band in front of crowds shouting, "Get off! No! 
We want normal music!", I think that was more like acting than anything 
I've ever done.
