It would be more helpful if you told us what the notification(s) said.
And what were you doing when this happened?
And does this happen every time?
And what version of MB are you using? (Help > About)
And how was MB installed? (Installer, Portable, Store)
Have you checked for the latest audio drivers?
Have you done a recent Windows update?
I can't recall anyone else reporting something similar, so my initial thoughts are that it's something on your particular set up.
