Hi Jeffrey,

1. I saw you add 4.7Kohm resistor on each audio input pin. This resistor will affect the gain setting and also have pop noise risk.

2. Suggest the LC caps of one channel can share same GND points. For example, the GND pins of C36 and C40 are connected together on PCB layout.

3. Add GND vias between OUTP/N.

Regards,

Derek

Hi Jeffrey,

Add GND vias between OUTP/N.

Others are fine.
