Hi, my name is Rob and I am having some audio problems. I have done a lot of research and I have finally found that I might need to switch from my Audigy 2 ZS to an Audigy 2 NX. Audigy 2 NX: http://www.soundblaster.com/products/product.asp?category=1&subcategory=204&... Audigy 2 ZS: http://us.creative.com/products/product.asp?product=4915 The reason that I am thinking of changing, from what I understand, is that RAT doesn't work with Audio devices that appear as separate input and output devices. So I went to the AccessGrid.org website and researched the Audigy 2 NX. I guess my real question is do I need to change, and will the NX support a XAP 400? Here is the Archive that I got the RAT fact from. http://www-unix.mcs.anl.gov/web-mail-archive/lists/ag-tech/2007/05/msg00005....
