Sometimes in XP you need to install the MS UAA driver also, at the right time. The best thing to do is to contact HP customer service and ask for "how to install XP" instructions.
I need help getting sound back on my desktop, as I had to reinstall Windows XP after I got stuck in a reboot loop after I updated my antivirus/firewall solutions (by ZoneAlarm btw). Now I have no sound and I can't get it working, even after going to HP's site and downloading the drivers there.
My computer is an HP Pavilion m7480n Media Center PC. If anyone can help me get the sound back, I'll be grateful for the help.
