I installed WIN XP in a machine that already had Windows Vista in it and Audio and other multimedia was working fine,but after i installed WIN XP the AUDIO is not working,all the options are disabled when i open the Sound and Audio Devices property tabs..i also tried the services.msc in the Run command and opened the Services and tried to go to the Windows Audio Properties Tab and the Services buttons were disabled as well,so please help me to make the AUDIO work in my system....
