1. Method to control a hybrid powertrain comprising an engine, an electric machine, and a transmission, the method comprising:
- monitoring operation of the powertrain;
determining, by a processor, whether conditions necessary for growl to occur excluding motor torque and engine torque are present; and
if the conditions are present, controlling the powertrain based upon avoiding a powertrain operating region wherein the growl is enabled.

11. Method to control a hybrid powertrain comprising an engine, an electric machine, and a transmission, the method comprising:
-
monitoring operation of the powertrain; determining, by a processor, whether conditions making growl more likely to occur excluding motor torque and engine torque are present; and if said conditions are present, controlling the powertrain based upon avoiding a powertrain operating region wherein the growl is made more likely.
