I have read all these e-mails that talk about a mysterious "multimedia audio controller" showing up in the device manager. I have "kill disc'd my computer twice and this insideous thing won't go away. I have no sound despite trying most of the solutions that I have read. What's the solution?? Thanks and Merry Christmas in advance.

More information is needed:

What brand is your computer ?
Have you checked their website?
Which operating system??
