I am able to control the left and right speakers on my MacBook Pro in Audio Midi Setup, but the master volume is completely disabled, as in I can't use the keyboard or audio window in preferences to change volume. The only way to change the internal speaker volume is if I manually change both left and right speaker outputs through audio midi setup. Would greatly appreciate any help.
