How do I remove the plastic trim covering the left speaker?

How does one remove the light gray plastic trim that goes around the inside of the tablet after removing the back? The plastic trim is covering up a screw that needs to be removed to replace the left speaker. It also covers the 2 screws that hold the micro USB charging port.

The tablet needs to have the back cover removed by gently prying between the chrome trim and the display, not between the chrome trim and back plastic.
