My computer has no sound. In the bottom right in the system tray it has an x over the speaker and says No speakers or headphones are plugged in. I am using a M4N78 PRO motherboard and I have the disc that comes with all the drivers. The audio drivers will not install and prompt me with the error "We cant find hd audio device". My system has no audio and i cant download drivers to try to fix it, it's like windows isnt picking up the sound card at all.
