I have a Dell Inspiron 1525 laptop with Windows Vista Home SP2 32 bit. My sound is not working at all. I was uninstalling some unused programs and got distracted. I am afraid that I uninstalled something related to my sound. I have researched several websites and tried several different methods to get my sound back. It seems that my "High Definition Audio Device" is corrupt or missing (code 39). I have uninstalled, re installed, and updated and this driver and it doesn't seem to restore it. Also, I have a "Sigma Tel High Definition Audio CODEC" driver that is also corrupt or missing (Code 39). I have gone through several posts on this website and came up empty. When I hoover over the "speaker" symbol in the right hand corner of my computer a message comes up saying "No Audio Output Device is Installed".
Does anybody have any ideas that I can try?. thanks.
