If I am understanding correctly....
You could use the PS as is, and add a linear regulator (LM317) circuit to the tail end of your 9V supply to create the 5v source. Something like this: http://www.energiazero.org/arduino_sensori/lm317_dc_dc_converter_step_down_circuit.pdf but there are others. I see that a few of these modules are capable of 1.5A, but the device itself is capable of over 2A, probably determined by heat sinking. or a DC-DC (switching) buck module, something like this https://components101.com/modules/xl6009-dc-dc-step-down-voltage-regulator-module that would supply more current, run more efficient, and require less heat sinking, but because it is switching, not sure if it would cause any emi problems to the pi or any nearby low level audio signals. Note that I am familiar with both circuit designs, but have never used the modules in the links I supplied, I just went out and looked for examples.
