I have 2 Layla 24's on a P3 933MHz with Win2K (stongly considering switching to XPP). The first card records/plays fine, but the 2nd card records at twice speed (shorter/higher samples at double the pitch). I compared the sample/bit rates (48K/2048) and they are the same, and the cards both show the 6.05 drivers. Might this be an OS prob, IRQ, or something else?
