Re: xCORE-AUDIO Hi-Res DAC/HPA Platform Hardware(DAC) volume

Absolutely - XMOS could take this product to the next level very easily - I am trying to help them see the light. I already have a working solution - but XMOS solution "could be" as good and a bit simpler than the one I am using if they just implemented volume control via I2C. :) That woul...

Re: volume control in DAC and DSD volume control in DAC. It all depends on the DAC, some just have basic digital volume control DSD volume control can just be digital after DSD->PDM conversion Case in point, WM8742 You should consult the data sheet of your DAC.
