Matrix Analog Direct port: After upgrading a frame from ECS to EHX direct ports won't pass audio IF they are part of a PL group

Problem:After upgrading a frame from ECS to EHX direct ports won't pass audio IF they are part of a PL group.  Monitoring the direct interface (port) works fine, but there's no audio if the port/interface is in a PL group.

Fix: The way around this is removing the port, applying changes, and re-configuring the interface.
