I am having the same problem. My mic works on my brothers Dell, but not mine.
I've been through all the steps of checking my volume and settings and all.
In the Audio tab of Sound and Audio devices Control Panel, my only option
for "recording" is SigmaTel Audio, and not just simply "micropphone" like
I've seen on other laptops running XP I've had.
Any help is apprec.
Thanks
