I have a question about the status of Allwinner D1 audio codec driver (sun20i-d1-codec).
Currently its status is marked as work in progress by Samuel Holland. And sure enough the audio capture doesn't work at moment, at least on Lichee RV dock where on-board mic is wired to ADC3. alsamixer is unable to set levels for MIC3 PGA even with fixed sun20i_codec_pga_vol_scale values.
I would like to capture sound with that onboard mic for my project :) There are a lot more important things indeed and there is a lot going on with upstreaming bits and pieces for D1 (I can't be thankful enough for that!). But can we hope for a working audio capture in near future? :)
