Marc P. - sorry I haven't gotten back to this - am getting S11 all settled in and dealing with other problems & upgrades to my editing system...
By pulling, shuffling and reinstalling most of my PCI cards (not fun), I finally found a configuration that let my Audigy Gamer card work again flawlessly - so I ended up not needing the Turtle Beach card. As such, the Creative ASIO box doesn't appear anymore...
Thanks much for the response...
