No sound on Pine A64

Hi,
I’ve installed DietPi and Squeezebox/Squeezelite on a Pine A64 2Gb, but I can’t get sound out of it.
I’ve tried selecting all the three options in the Audio Config, also tried adding a USB DAC that worked on my Raspberry Pi, but I can’t hear any music whatsoever. :frowning:

Also this:

dietpi@DietPineA64:~$ squeezelite -l
Output devices:
  null                           - Discard all samples (playback) or generate zero samples (capture)

does not look normal, it should show the available soundcards…

Any suggestions appreciated.
Thanks
