Default Help regarding LA4227 wiring

This is my first attempt at wiring an amplifier that will accept PC lineout signal and feed to two 3ohm 3w speakers. For this I have used LA4227 IC and followed the recommended wiring by SANYO. But I must have goofed up something since when I turn power on, the speakers start to make loud roaring noise so that I have to turn off power to prevent damage to the speakers. This happens when I have not even connected the inputs to the amplifier, regardless of I touch the ground of the circuit. Can somebody shed light on what possibly went wrong?
