I'm currently running Parallels on an Intel Mac with Leopard. I have installed Windows XP through a typical install. The program runs fine, but I have no sound. I have installed the Parallel Tools over and over, but no joy. I've reinstalled the program, but the same problem persists. I'm not running the program through Bootcamp. The Sigma Tel Audio driver is installed and activated. In fact, it is the AC'97 that I think is causing the problem as XP has it's own sound drivers and they seem to work (I got the Windows orchestra when I first started up). However, I simply cannot delete the damned Sigma Tel Audio Driver! When I uninstall it and restart Parallels, it is right back there. I've tried setting up windows so as not to accept drivers, but nothing can stop it sneaking back in. If you totally switch of sounds on the VM config. then there are no sounds at all. Is there a way to delete the AC'97 driver? Am I on the right track do you think?
