Last week, my sound stopped working for no reason. I checked my speakers connection and everything was fine. I started messing around on my configuration pannel and they finally worked again. But yesterday I ran Call Of Duty 4 and I lost the sound again.
If i plug my headphones they works perfeclty. It looks like my realtek HD audio manager doesn't detect my Bose speakers.
I also tried to move the volume up and down and nothing changed.
Sorry for my bad English, and thanks for the help!
