I'm coming across the same problem it seems all Audigy users on Vista/7 are having with seperate subwoofers in surround sound configs. I bought my setup not too long ago and I have tried many things to get the subwoofer to play the LF parts with no sucess. The only thing I can do is turn my 5.1 to the AUX channel and let it do the work, but then I lose 5.1. I tried the PAX drivers for thie bass management/redirection and not only can I not see any option to do the above, there is little to no difference I can distinguish from the stock creative drivers. I'm really getting anoyed since I basically paid for a good thing to get no decent use out of it. Is there something Im missing here?
