Hello and Thanks for the response.
You cleared up a lot of misunderstandings especially with the chip.
Journey of discovery.
With a little bit of work, I now have sound.
I was powering the unit through a USB powered Voltage Regulator which I guess was not putting out enough mA.
I hooked up a 9V through a Voltage Regulator 7805 to power the project. This fixed the sound problem. So I now have enough mA.
Please see my youtube video for demonstration.
Now all the issue is, that I cannot see the bottom of the screen completely and the words as chopped off (See Video)
Here is the Sketch I am using;
