The resistor values depend entirely on the kind of LEDs you are using, the value can't be predicted without knowing their forward voltage drop and the current you intend them to pass.
TIP31 has emitter, base and collector pins, you don't show which is which. It might work if you connect the negative side of the battery and the 'ground' side of the loudspeakers to the emitter pin, the other side of the loudspeaker to the base pin through a resistor (100 Ohms is a good starting value) and connect the collector to R1 - R5. Don't expect spectacular results but they should then flash.
