>ordered cheap PAM8403 as headphone amp
>hook it up, notice humm/ static noise
>Google the issue, find something about caps/ low-pass filters
>add 1000Mf cap across 5V input, gets rid of some of it, low-pass filter distorts audio
anything else i could try or keywords i can look up? I'm using it with a 5V powerbrick and audio coming from my pc's 3.5mm out. I'm a beginner when it comes to electronics
