We were able to control a LED strip using audio input. A simple which is shown below was created:
Audio output from the computer was provided to the circuit using a 3.5mm jack. The black wire of the LED strip was connected to Vcc(+12V) and one of the wires Red/Blue/Green was connected to the collector of the power transistor TIP31.
We made a short video to illustrate this:
