The capacitor C110 - 470 uF? Try replacing it?
"Try to add some capacitors to the audio amps power supply line and see" Can not you send me a diagram of where to place the capacitors and with what capacity? I'm not that specialized :(

You are hearing the LOOP refresh of the nano controlling the SI chip. What is strange is that you can hear it with the
volume control disconnected.
Try to add some capacitors to the audio amps power supply line and see. It should go away. The filter capacitor C110
may not be soldered properly or defective.
