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?
