Audio Question

Hello, I am a mega noob when it comes to just about every electronical. So I feel as if I am asking a dumb question. Anyways I have gotten my whole gameboy to work very well by studying every piece of information I could gather. The only thing that I can not get to work is the speaker I bought. I just wired it up as the diagram stated for the Helder 2.2 board. Just wondering if there is a blatant miss-step I'm taking because that could very well be the case. Thank you ! :)

No

Put your sd card into your computer and open the file named config.txt with a text editor add this line
at the end of that file:

Code: Select all

dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

I got the audio to slightly work, but it sounds off and is very faint. could be a volume wheel problem? I'm not sure.

Maybe
But check the system volume first
Start > Sound setting > System volume

Alright that did help significantly, but now it sounds like slowed down or almost like inverted? I guess that its good that were showing progress with each step at least lol.
