    My sounds icon on the task bar is gray now and I am unable to adjust the volume or mute, though the sound does play at about 40% (probably last setting before upgrade). Not sure what's going on and I'm done all the searching I can. Aside from fresh install, anyone know what I can do?

    Try going into the Sound Settings in System Preferences and make sure everything is working there. If everything checks out, try resetting PRAM.

    Have you tried plugging and unplugging some headphones?
