The problem is in the sun50i-a64-pine64.dts the lines to enable i2s2 and sound_hdmi or missing. If you add those lines, you get the allwinner_hdmi sound card. But as mentioned before the sound is not OK, it goes constantly on and off. If somebody has a suggestion what could be the problem... Maybe this is the reason they dissabeld hdmi sound in the dtb.
I found the problem of the crackled hdmi-sound. Seems to be the RTL8723BS driver when you enable it to get the wifi add-on board working. When you want hdmi-sound and wifi working together, you may not build the other RTL8723 stuff in the kernel or as module. When you compile the kernel with only the RTL8723BS as wifi driver, hdmi_sound and wifi are working nicely together.
