Hi, Lin,

Thank you for the circuit schematic. What I would recommend is to remove the output components between the LM4871 and the speaker. This device doesn't require of intermediate components for the correct behavior. Otherwise, there could be an additional current demand and pop issues due to these components.

Best regards,
