Switched to a wired apple keyboard and now the play, and skip buttons don't work
Recently i switched from an aluminum wireless keyboard to the aluminum wired one (with the number pad) and the play and skip buttons don't work. I've already gone into preferences and turned on and off the F1, F2, etc settings and still not working.
Please help.
iMac (27-inch Mid 2010), OS X Yosemite (10.10.3)
