Reboot your Mac Pro.
Music still playing?
Press Command + Option + Esc and see what other apps are running.
Go from there

I feel like an idiot that I can't figure this out. Every time I un-mute my mac pro I get the same tune playing, it is not familiar to me, does not seem to be in my library (using command L) I cannot stop it, it continues to play even if I play another tune. WTH is this? How can I get rid of this monotonous, unwanted tune? I don't even know where it came from.
very frustrated! Thanks for any assistance
