Hello all. I have a Macbook Pro. I'm up to date with Parallels 9 and Mavericks. I've noticed this issue pre: Maverick and pre-Parallels 9 and the upgrades did not chance the situation. I have my sound on parallels as off and the volume on mute. Even my Macbook pro is set for mute. I keep hearing a clicking sound. It's two clicks with 2 secs between them. It happens whenever I get an email in Outlook on the parallels or when I do something like empty the trash on the parallels side. I've yet to hear it with parallels off so I'm assuming the click is coming from Parallels. To give an idea of exactly what the sound is, when you zap the PRAM on the Mac, when the computer switches over, that exact click is the same thing I hear. Has anyone else noticed this? I'm still under warranty for Apple in case this is a hardware issue and not just parallels but I wanted to make sure first that this isn't just a setting i'm missing.
