this seems the best option. should be put in the docs perhaps.
the only thing is that it may intriduce extra CPU usage but that should be 
for the user do determine if a plug swap or a s/w swap is desirable if 
different players in use do different things.
Ive checked and the code aleady puts things in

SL,SR
C,LFE
order so everything should be ok.
still looking for a corruption and jan's funny video is puzzling too.
