non standard DAC

Hello,

I’m working on a homemade DAC which has already been built and is functional with an headphone amplifier. Since the beginning, I’ve used raspbian and a command line reader. I would love to use volumio and make the device userfriendly.

I’ve tweeked some modules sources to make the DAC work within the raspbian distribution. It works quite fine but I really struggle to export my “homemade” kernel into the volumio distribution. Until now, I have only modified existing code and used the following tutorial :
raspberrypi.org/documentati … uilding.md

When I install the kernel (I tried directly on the SD card and by importing built sources on a usb and install from a functionning volumio), volumio does not start properly.

Could you guys help me with this ?

Many thanks !
