I do understand that not having a scope can make things difficult, not being able to trace signals in and out of an IC to determine its integrity.Also, I understand that you might have seen that sort of problem before and thus you concluded that the audio processing IC was defective. You measured 12v on presumably VCC which is labelled as 9v operating voltage. This to me would suggest that the IC was not loading the circuit down. Also, you did not mention the measured voltage on the output pins.
