Hi!
I'm right now building my portable gamecube, and I already soldered the component cable to the device, but I kinda noticed that If I turn my Gamecube on (it uses some custom regulators with 1.9v,3.3v and 5v ( for the 12v line, the audio amp, the rumble function and the screen ) the sound is pieeping I dunno how to describe it, if im in the bios or the original gamecube menu (not swiss) I hear next to the background music some weird noises, as if the amp is giving too much voltage on the speaker, I also directly connected my headphones to the audio out of the gc and there I heard the same noise.
D: What should I do?
(I also tested different wires and shielded wires with no success)
PS: my current 5v audio amp is the PAM8403 Mini Power Amplifier Board
