GameCube handheld audio issues
Posted: Sun Mar 20, 2016 6:31 am
I have this issue with the gamecube handheld I've been working on: there's this grating buzzing coming from the speaker that I can't get rid of.
I've tried a different amplifier, speaker, power sources (for both the entire thing and just the amplifier), I even tried pulling the signal from different places on the board.
When I disconnect the speaker, I can hear the amplifier making a very quiet buzzing sound too.
The sound changes drastically when I use a different power supply.
I don't know what to do at this point. Anyone have any ideas?
I can't figure out how to properly imbed a youtube video, so here's a regular link:
