Two main steps are required :
1] Alter the /boot/config.txt file to add the device tree :
echo 'dtoverlay=audioinjector-isolated-soundcard' >> /boot/config.txt
2] Make sure the Linux kernel is a recent version, post July 17 2020. That is kernel versions : 5.4.58 or a 4.19.xx version

The DAC compatibility should be updated here to automate this process :

Turns out that Volumio Buster beta has a recent enough Linux kernel to support the isolated soundcard.
I just made a pull request to add The isolated and ultra soundcards to their system :
volumio/Volumio2#1999

Which was merged blindingly fast :) !!!!

A soon future release will support this out of the box ... nice 👍

Just testing volumio beta, which includes audio injector Isolated support.
Unfortunately I had to login and execute :
sudo modprobe snd_soc_cs4271_i2c

This is because it is using the 4.19.118 Linux version, rather then the 5.xx.xx linux version.
