For the records: We don't need simple-soundcard, but we seem to need an
audio routing entry. So I tested this successfully on the X96 Mate with:

&codec {
	allwinner,audio-routing = "Line Out", "LINEOUT";
	status = "okay";
};

So can you add a patch adding those properties to the boards with a 3.5mm
jack? The OrangePi Zero2 and Zero3 do not have such a jack, but route the
LINEOUT signals to dedicated pins on the 13-pin header. Not sure that counts?

Cheers,
Andre
