Hi, everyone. I'm having a problem with my MacBook's volume control. Whenever I turn it on and log in, the volume is turned way down. Even though it was turned all the way up when I turned it off. If anyone can tell me why this is happening and how to fix it. It would be greatly appreciated. In case it's needed, I'm running an Intel Mac OSX. Latest updates. It's a mid-2010 model. Almost brand new.
