I just bought and set up a system with an ECS NFORCE4M-A Motherboard. I've downloaded all the most up-to-date drivers for the RealTek AC97 audio and still no audio device is detected on my Sound and Audio Devices Properties in the control panel. I downloaded the High Definition AC97 drivers at the suggestion of another board to no avail. I've also checked the status of the sound in the BIOS and the AC97 peripheral is set to Auto. There are only two options for the AC97 available: Auto and Disabled. I tried installing a PCI sound card to get this to work and still no audio device available even though it installed correctly. A tech support guy from the place I bought the motherboard says it's an OS issue with Windows XP. Is that possible? I'm completely lost on this...please help!!! Thanks!
