Hi everyone. The noise happens for me also. I am on Parallels 9.0.2 [MacBook Pro Retina on OSX 10.9.4]. Was hoping it would be fixed in the Parallels July 2014 update but no such luck. The noise sounds like a "machine gun" noise - can go for up to 7 seconds sometimes. Gets plenty of unwanted attention and unhappy responses from colleagues in the office and especially when in a meeting room :-( It is when I switch into a VM - my best attempt to pin point what causes it is that it happens when there have been some Windows notifications happen in the background. E.g. when MS Outlook has Appointment Reminders prompts that have occurred when I wasn't "in" the VM. My best guess so far. So I keep SOund turned OFF all the time unless I need it. Pretty sucky :-(
