I don't seem to have sound on my computer. n.n; That is, from the speakers anyway, My computer, the actual PC, makes a beeping noise once in a while when I start up. Anyway, recently, I upgraded my OS Win XP sp2 to Window 7 Utimate, everything seems fine except I don't have any sound. When I checked the device manager, under Other Devices, Multimedia Audio Controller had a big yellow question mark in front of it. I tried to uninstall it in safe mode, and then restart it normally, it didn't work. When I got back on, I tried to reinstall it, but the computer couldn't find the software for the controller. u.u; So...help?
