I've been having a problem with the volume on my macbook. The volume buttons make the sound, but the volume doesn't go up or down. The problem sometimes goes away when I plug my headphones in and out, but not always. Is there a fix for this?
Sometimes the volume keys work, other times they don't. When they don't work I have to go into system preferences and manually change the volume. I'm using the 2.0 alum macbook.
