Sound on Armbian

[Bram]

After trying DietPi and Manjaro, I've found that Armbian has been working best for me, with a working sleep and wake, e.g. But I have been unable to get sound from it.

Code:

$ sudo inxi -A
Audio:
  Device-1: simple-audio-card driver: asoc_simple_card
  Device-2: simple-audio-card driver: N/A
  Sound Server-1: ALSA v: k6.1.11-rockchip64 running: yes
  Sound Server-2: PulseAudio v: 15.99.1 running: yes
  Sound Server-3: PipeWire v: 0.3.48 running: yes

I know the speaker itself works physically, because I did have sound under Manjaro.

Does anyone know what could be going wrong with sound in Armbian?
