I have just created a VM for windows 7 and everything is working great except that there is no sound. It says that there is "no audio output devices are installed." Audio works fine with native OSX, no sound from Windows 7. Parallels Version 9, fully patched, Mac OS 10.8 (fully patched) 13" MacBook Pro mid 2012. I have cut/paste this issue from an identical post from 2009. Reading that did not solve my problem. I'd really appreciate any suggestions on this problem, thanks.
