I have two annoying issues that were present in Parallels 9 and are still present in Parallels 11 (I keep seeing the scene from Tron:Legacy where Alan ask what is different in the new version). The two issues are: 1. It seems like the sound driver goes to sleep and when it wakes up on a new sound, it plays static/garbage at the start. 2. I am using a laptop with a second monitor. At certain times when the guest is doing something, the display will dim. Any suggestions on either of the issues?
