After updating to 10.4.8, my volume control is spazzing out. My external speakers are working, all my normal sounds are coming out... but the volume control keys on the keyboard are adjusting the volume for the Internal Speaker... ?? I can use the mouse and adjust the volume from the menubar, but not the keyboard. Anyone else having this issue? It worked perfectly up until about 30 minutes ago when I installed 10.4.8 edit: Sorry, it's a Mac Pro.
