My sony-vaio desktop (xp home, sp2) has got two drives, a DVD-ROM drive and a DVD+/-RW/CD-RW drive. The computer is 5 years old and has always played back my CDs and DVDs without problems. Until this morning. I did not change my computer in any way or install/deinstall anything. Suddenly, there is simply no sound when I try to play back DVDs in either drive with PowerDVD or with Windows Media Player. The image is fine with DVDs - but no sound. And if I try playing a CD in Windows Media Player, I am told that there is a problem with the audio device - all the menus are in German, so I am translating here. But other sounds work (streaming content, mpeg-4 files, computer sounds like e-mail notification etc.). My loudspeakers are plugged in (well, they've got to be if the other sounds are okay!). What is wrong? I checked under device manager, but everything seems to be okay, nothing is set on mute, there seem to be no conflicts...Can anyone help me? And below is a snapshot of the audio devices on my computer (they're indicated in German), and there's no red cross or any other mark which may indicate that there's something wrong with them.
