I have a Raspberri Pi 4 and had set up BalenaSound so I can use multiroom when connected via bluetooth. It seemed to work fine so I thought I would add a HiFiBerry Digi+ as one speaker doesn’t have an aux input. Unfortuantely after connecting it via optical cable and adding the BALENA_HOST_CONFIG_dtoverlay hifiberry-digi`
no music would play through it. It did however send audio through to the other Raspberri Pi running BalenaSound.
I have tried changing the Define DT parameters to "i2c_arm=on","spi=on","audio=off"but still no dice.
I have put HiFiBerryOS on the Pi and the Digi+ works fine through the optical cable.
The only thing that looks odd in the logs that I can see is
