Hey guys, we’ve made the changes required to integrate pisound into Raspberry Pi kernel and submitted a pull request. https://github.com/raspberrypi/linux/pull/1684
It is functionally equivalent to the out-of-tree kernel module which is installed with the current installation instructions, but if you’d like to try it out anyway, you may find it here: https://github.com/BlokasLabs/linux/tree/giedrius/rpi-4-4.y-pisound and you may build it using instructions provided here: https://www.raspberrypi.org/documentation/linux/kernel/building.md
Having it integrated into mainline kernel will allow us to get rid of the bulk of the steps that are currently necessary to get started.
