• Test the speaker with a multimeter. Replace if damaged. The sound is distorted because the speaker is weak or it has burned out.
• If the speaker is good and there are no problems, make sure that the terminal is not biased. Then clean the contact pads of the buzzer connector to avoid possible oxidation (which can weaken the connection).
• Check each corresponding buzzer + and buzzer- paths to each component where it is being connected.
• If any speaker + or - track is missing then replay.

In this case, you can try a wire that connects directly from the speaker's pins to its retaining pins. I have fixed this problem many times by re-soldering the latches of the speaker cushions.
