These problems turned out to be caused by the kernel side.
The issues is as follows (0.7.9: gitlab-ci-linux-build-67: 4.4.132-1075)
1. "es8316-sound" no sound.
2. "spdif-sound" no sound.
3. "serial-console output" contains garbage.
All of the above issues have been solved by modifying kernel.

*Additional information)
At currently the newest kernel (4.4.154-1122),
all sound (in addition to the above, "hdmi-sound" also) can not output.
I also confirmed that it works correctly with the same modification.
I agree with your findings on 4.4.132 & 4.4.154 kernels - what mods do youu apply to the kernel to correct things?

- PinePhone Pro Explorer Edition, daily driver, rk2aw & U-boot on SPI, Arch/SXMO & Arch/phosh on eMMC
