I have an HP system with a realtek HD audio manager. Recently my computer has started skipping/fast-forwarding through music forcing me to restart iTunes (or whichever media program I am using) which USUALLY fixes the problem. I think the problem started after upgrading to Windows 7, but my machine was supposedly designed for Windows 7 so I can't see how that would be the problem. The problem most often surfaces after I have played a file containing audio in another program (i.e. web browser) but not always. Apparantly I have the most up to date drivers for the realTek device so I'm at a loss on what to do to fix the problem.
