There was a new lost spoiler posted on spolier buzz today and I was going nutz cause nomatter what I did I could not hear the fricking thing. Then I noticed it wasnt just there it was Flash. After hours of searching forums I came across the dumbest solution….
Open up garageband play the piano, close garageband, reboot.
Guess what… it worked.
So anyone out there if you run into this its the ONLY thing that I could find fixing it and I tried everything believe me.
