For a while now I have had no sound on my laptop. I have tried numerous things, downloading drivers etc but nothing seems to work. If I try to play music through windows media player I get a message saying: Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly. My computer tells me that I have no audio device. I also tried downloading an audio device and an error message came up saying: corrupt cabinet file. Any ideas what I can do?
