Hello, my first post here! Here's a good one for you. Have had a Soundblaster Live! 24 for a coupla years, works fine. Recently changed my m/board after a failure to a Gigabyte GA-P35-DS3P, and very nice too. I was using its onboard HD audio until my Avid Xpress suite refused to install - it needs an SB compatible card to work. No problems, uninstalled HD Audio, deactivated from the BIOS, and installed the Soundblaster. Downloaded the latest drivers, and I was away.... ...until the PC came out of standby, whereupon it refused to believe I had a soundcard at all. Reinstalled the driver, whereapon it told me I definitely had no hardware. So powered down, removed card, powered up and down, inserted card, powered up and it found new hardware. Everything working great again. Suspicious, I powered down and up again... and low and behold, no hardware any more. All ideas gratefully received! Am happy to buy a new soundcard, but could it be an IRQ conflict or something? PCI IRQs are set to Auto in the BIOS.
