I'm a ubuntu noob. Speakers work fine, but plugging in headphones = no audio. Take it out and speakers work fine again. Checked alsamixer, saw that the head phone jack was "muted" (MM) and 0. If I make it (00), and up the volume, the headphones work. Unplug headphones and plug back in, and it's muted once again (MM).
