No sound from DAC+

A little update from me, I just installed HifiBerryOS to check, whether my DAC might have a hardware problem.
With HifiBerryOS the RPI with DAC works flawlessly out of the box, so there must be something wrong with my setup in BalenaOS.

I also tested with my DAC+ Zero with BalenaOS, changed “BALENA_HOST_CONFIG_dtoverlay” to “hifiberry-dac” which works perfectly.

Here is what I do to install:

  • Download OS for RPI
  • Boot RPI up
  • Change Define DT parameters “i2c_arm=on”,“spi=on”,“audio=on” to Define DT parameters “i2c_arm=on”,“spi=on”,“audio=off”
  • Add BALENA_HOST_CONFIG_dtoverlay hifiberry-dacplus
  • Disconnect power
  • Boot

Is there something wrong with my way here?
