suggestions. 1.- check the voltages of each pin of the audio ci. 2.- remove the ci and check the voltages, this so you can compare the voltage drops. 3.- with an external audio amplifier, you use it as a "tracker" you place a 0.022 uf capacitor, and check if you find the signal. With this you can inject signal into the amplifier input. Regards. Felipe ascencio
