Most audio boards have an LED that lights up to indicate power and operation. You could also verify that the driver for the board is configured. You would see the line below in /boot/config.txt
Code:dtoverlay=justboom-digi
If the driver is correctly specified then reboot and look in dmesg log for i2s success line or i2s error lines. Below is an example from my Allo Boss2 DAC.
Code:pi@rp2:~ $ dmesg | grep i2s

Hello Tim, I checked the point you mentioned :the driver is correctly specified in the file config.txt and the hat is OK (initially I thought it was fried). Would you mind having a look at the driver justboom-digi.dtbo (maybe an issue with the compile?, the chip seems to be Wolfson WM8804G)
