I picked up this PCI soundcard second hand. Like a lot of cards I'm coming across (mostly stuff involved with Compaq) it had no FCC ID anywhere in sight. On back of the board it says OnSpeed. Fortunately the Crystal logo on the chip is fairly prominent. I got this driver HERE, on Driverguide, searching with Crystal chipset number. So here it is under a different name for those going "OnSpeed". By the way, it worked like a charm. When windows said it detected the device I just pointed it to the floppy I'd unzipped to. The setup file was'n necessary.
