Hello

I Have this DAC for my Pi Zero W (https://www.inno-maker.com/product/hifi-amp-hat/): in theory, powering the DAC with a 12V and 5A power supply should be able to use the raspberry with only one power supply.
I don’t understand why but when I power up the DAC the raspberry doesn’t start. Can you help me?
