Does anyone have any suggestions for fixing sound issues with the original GBA? The sound through the speaker and headphones is crackly at best and cuts out or is very very faint most of the time. I thought it was just the speaker at fault and switched that out but it’s still the same. Thanks in advance!
In the end, it was just a dirty headphone jack. I cleaned the headphone jack with a cotton bud and some rubbing alcohol and that seemed to do the trick. Thanks to @thisdoesnotcomp on twitter for the suggestion.
More than likely the issue will be with capacitors. They go bad after time and need to be replaced.
