I have finally assembled a complete PCB, there are few change I will make on rev 2 but I have a prototype working. The power down function on this prototype isn't working yet and is kinda fixed by adding a slide switch. I've also decided to switch back to a PCM5102 DAC because I couldn't get a good enough clock pulse from the RPi to provide the CS4344 DAC with a MCLK. If I want to use this DAC I will have to add an external clock and for this I would have to redo the PCB and hope that I could get the drivers working. That's why I have decided to go back to the PCM5102 DAC on this prototype the DAC is sandwiched between the PCB and the RPi.

Just wondering, do you have any headphones amplifier? PCM5102 minimum load resistance is 1kOhms according to the datasheet.

  Are you sure? yes | no
