    Hi Julian,

    I'll add some comments below:

    • Common mode filter capacitor is not needed for this device, so you can either remove or keep C385 as DNI
    • I can't see decoupling capacitor on SPK5V0 in the schematic, you should at least place a 0.1uF capacitor close to the device, if possible add a 10uF along with 0.1uF

    Best regards,

    Julian,

    The layout is looking good. I would keep short traces at the outputs but I think the speaker connector is not visible in the capture.
