If I play an audio CD in my DVD drive, the sound is fine, but if I play a DVD, a movie for instance, there is no sound. The video seems to be fine, but no audio. I also do not have the usual "Windows" system sounds, either. None of the little bells, whistles, chimes, whatever, that Windows uses, are audible. Has anyone else had a similar problem? Naturally there is NO help on the Microsoft website. Have yet to find the solution to anything using their support menu. If anyone can help me with this, I would appreciate it. Thanks. Dennis
