Try Equalizer and pick a preset that cranks them all, or at least one that cranks most of them. I use the Rock preset. My phone has been a bit louder since installing this. Pocket mode probably works off the proximity sensor, maybe even a light sensor. But I'm betting just the proximity sensor that is built into the ear piece. It must figure that if the phone isn't making a call and the proximity sensor senses stuff around it, that it must be in a pocket. But that is just me guessing.
