Route INCM between associated

left and right signals of same channel

The INCM trace ends at the same point where the connector ground connects to the board ground (thru-hole connector pin).

Place test points, resistors near audio connector. Connect the other side of the resistor to GND as close as possible to the ground connection of the associated audio connector.
