Is there a way to do this through a terminal command or an app? I often find my MacBook's speakers to be too dinky, no matter how much i crank up the volume, both the master volume and the app's volume. I have external speakers but sometimes I need to use the internal speakers, and often iTunes or DVD Player is far too quiet. Such a simple thing, but I haven't been able to find a way. Anyone know of the Terminal command? Thanks.
