BalenaSound (balenaOS 2.48.0+rev1) not working after installing JustBoom Digi HAT on Raspberry Pi 4

Hello there, just to confirm. When installing a DAC there are 2 extra configuration steps you have to make:

  1. Disable the on-board audio by adding ”audio=off” to the DT parameters in the device configuration screen;
  2. Add custom variable called BALENA_HOST_CONFIG_dtoverlay with DAC’s own dtoverlay value.

Did you set up both? If so, what value did you use for the dtoverlay?
