I have a Game Boy, and whenever it tries to play sound, the sound is very quiet but there's a loud clacking sound.
Here is a sample. In this case, it is Tetris Attack playing:
(I am not the author of this music. All credit goes to the composers (Masaru Tajima, Masaya Kuzume, Yuka Tsujiyoko).)
All of these sounds are created by the Game Boy. Even the large clacks at the beginning and end.
What might cause this? How can I fix this, preferably without replacing the speaker?
