I am connecting a circuit for Texas Instruments TPA3125D2 Class-D Aplifier.

Datasheet here: http://www.ti.com/lit/gpn/tpa3125d2

The circuit design is here: enter image description here

The circuit that was tested is not on pcb but on a solderless breadboard.

The problem is, that ALL I get, is some kind of bumping sound in the output speaker which does not depend on the input (no matter if input is connected or not, the output is the same - some kind of pulsation).

I do not get any output except this mentioned bumping sound.

That would be a great help, if someone experienced enough could review this scheme and give some critics or comments, on what is wrong here?
