creative audio pci is an es1371 w/some extra stuff. card is detected correctly, but not as es1371, and so sndconfig reports it as unsupported. running sndconfig --noprobe and selecting the es1371 driver by hand works. es1371 driver does not support all features of card, but supported features work correctly. rh6.2 detects and installs card as es1371.
