After reformatting and reloading Win XP Home, I have found that my PCI sound card will now not work. In the properties section of Device Manager, is the message relating to the driver. The onboard sound is disabled, the card has been removed and reinserted, and the latest drivers downloaded. Even when the onboard sound was enabled, it had the same message. The PCI card is Mercury with CMI chip and the m/board is Soltek SL-75KAV. Is it possible to change a setting somewher or do I have to resortto sledgehammer tactics of reinstalling everything? Thanks for any help you may be able to give.
