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.
