I have an odd problem with the Santa Cruz drivers "disappearing" from the Device Manager after a system start up. Windows XP Pro, SP2 recognizes the sound card, and asks to install the drivers. I can go into the Device Manager and remove the "Yellow" unknown driver, and restart. The sound will be normal after I do this restart. Once I shut down the computer, then start it back up, the sound driver/sound card is gone once more. This happens over and over. Restart the sound is ok, but shut down/start... sound card driver is yellow in the device manager and needs to be removed and system restarted before sound returns to normal... Anyone have any ideas on this odd problem?
