When i mute my sound and then unplug my headphones sometimes music starts playing. Additionally when I plug my headphones in and change the volume the sound plays from the speaker. Common problem? Worth getting looked at? Software? Hardware?
 
There are two volume settings on your MBP. One is for the built-in speakers and the other is for external speakers/headphones. If you mute or set the volume with headphones/speakers plugged in, that has no effect on the mute/volume setting for the internal speakers, and vice versa. If you're getting sound from your internal speakers with headphones plugged in, make sure the plug is all the way in.
 
I just did it again. I plugged in the headphones and then played with the volume buttons, there was like a 3 second lag where the sound effects were playing out of the speakers. headphones were definitely way in.

There may be a short in the headphone cord or plug, or in the MBP audio in port.
