There is no audio jack on my R5S, see [1] and I don't see it on R5C
either, see [2]. I don't see audio output on the pin header either.
How is it supposed to work?

It looks like rk809 doesn't have #sound-dai-cells property and it
results in a warning:
arch/arm64/boot/dts/rockchip/rk3568-nanopi-r5s.dtsi:48.27-50.5:
Warning (sound_dai_property): /rk809-sound/simple-audio-card,codec:
Missing property '#sound-dai-cells' in node /i2c@fdd40000/pmic@20 or
