Excuse me for not following here, but Walker, could you point me at
where in the schematic for the VisionFive 2 that this wm8960 actually
is?
I know ~nothing about audio, but good old Google tells me that this is a
dedicated codec chip and I was looking at [1] and could not easily find
it on the schematic.
Thanks,
Conor.
