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.
