I can't get the onboard sound to work on a computer I'm trying to fix. It's got a MSI K9AG-Neo 2 motherboard with a AMD 6000+ CPU. Running Windows XP Pro SP2. I tried down loading and installing the latest drivers from their website but part way through I got an error message saying the install had failed. The only thing different about this system is it has a Silicon Image Sil 3114 Sata Raid controller card with 2 mirrored hard drives. could this card be interfering with the onboard sound?
