I was working on my gameboy zero and everything was going fine. When I started testing sound and such It's been having problems. I get sound through both the speaker and headphones jack, but the jack has loud static with a good loud sound of the sound test and a the speaker is very quiet on the loudest setting but also has static. What can I do to fix it? Do I need to get some resistors or ferrite beads to fix such a problem?

did you add a low pass filter to the audio line(s)?

after that volume levels can be adjusted in the Mixer under audio settings
