DiY DAC

Hello Guys,

I’m pretty new to this forum, I hope you’ll be able to help me on my project.

I’m building a HIFI DAC based on the PCM1792. I designed the board with an embedded clock and I want to make the raspberry Pi a slave regarding the clock. I have tweeked the drivers for raspbian and it was working without being user friendly and required the full build of the kernel.

I know would like to use and enjoy the evolution of Volumio and don’t want to build the image every time (I confess I’m unable to do it for volumio). Could someone tell me how to build only one module directly from the raspberry pi ?

Thank you in advance for your help !

I think you should add a reclocking type of circuitry.this would require a lot of work. You could however add an existing i2s reclocking circuit in-between the pi and the dac.

I’m not expert in this field, but maybe you can inspire by audiophonics way. They have source code for volumio plugin for controling they DAC. Plugin contains modeles for kernel. It must be compiled for every new volumio version because new version of volumio have new kernel. Here is link:
