I have a motherboard (LX BN790E) with on-board sound (Avance AC97). I also have a Creative Sound Blaster PCI card. I would like to make use of and have both sound devices installed on my machine simultaneously. My problem is that whenever my SB PCI card is installed Windows XP doesn't recognise my on-board sound, yet when I remove my SB PCI card the mobo on-board sound works fine. Does anyone know how I can get both working at the same time and/or what the problem is?
