Anyone managed audio (line out) to work on Allwinner H3?

Included related modules in the kernel modules/sound support (sound-soc-sunxi), system has "sun4i-codec" running (but the platform is sun8i???), turned codec on in the device tree, defined audio routing. The log says

platform 1c22c00.codec: deferred probe pending

and that's all. Once, somehow, at some build, I was able to pass further when it said that it can't find routing (and yes, it was not defined in the device tree).

No idea what to do. Compared device tree with functioning Ubuntu, identical in codec section. Prebuilt image does not have sound driver at all.

No way - not supported?
