I have no sound device in WinXP. I have tried to download numerous drivers from Realtek, with no luck, yes I did remove old drivers first. I have installed xp at least 10 times, flashed bios, used different Mobo, nothing. I am currently using ECS KA3 MVP 1.0, with ALC880 driver for onboard audio. I have used two different versions of XP, both legit. Could my case be causing some conflict? Or maybe PSU? I am not very familiar with Admin. tools, but is there a way to ‘force’ XP to see my audio device, it saw it before. What could be causing it to not ‘see’ audio now, all I did was do a format and new fresh install of legit XP. Please help……thanks!
