I have been trying to use this LM386. Actually, when I used breadboard to build my 1st prototype, it worked fine (yeah still had noise but acceptable, at least i can understand the sound)
But now I am doing the prototype using PCB and its performance is very bad. I cant even hear anything except noise and buzz.
I also used decoupling cap for the power supply and an 8Ohm speaker.
