Hello, I hope someone from here can help me since I'm a dummy when it comes to sound-problems. To get in medias res immediately: I have just installed the 'AVI Movie Player' on my PC. So far, so good. But now, somehow, there does no sound come out of my speakers anymore. Not at all, not only when I'm playing the AVI player! I also plugged in my headphones but still, all I hear is the same old murmur. Anyone got an idea? Thanks in advance, Yoot.
