This board is very new and not mature in any way. If you use the radxa bsp kernel (debian) you have video, audio, wifi, etc... but with a modified version of the kernel with drivers and binaries closed in some cases. Mainline support is being worked on but it will take some time for the developers to add the necessary drivers and some may not arrive and even free and proprietary drivers may be mixed to make some specific features of each board work.
warpme is merging Andre's work (mainline kernel) with drivers that are in the radxa cubie a5e bsp to enable network ports for example.
in the sunxi kernel repo revisions of the "Display Engine 3.3" are being sent which adds video support for the new generation of allwinner (h616) soc among them.
The GPU drivers for the Cubie A5e board are present in the mainline kernel, so once the graphics engine is enabled, it should be easy to enable GPU video acceleration.

Thanks Juan, I was able to boot the kernel with some changes.
 
I used this extlinux.conf file. Changed the kernel to /Image and fdt to /dtb. I manually created a directory called extlinux in the boot directory. I then moved the extlinux.conf there. 
/extlinux/extlinux.conf
label ARMBIAN kernel /Image fdt /dtb/allwinner/sun55i-a527-radxa-a5e.dtb append earlycon=uart8250,mmio32,0x02500000 clk_ignore_unused console=ttyS0,115200 loglevel=8 root=/dev/mmcblk0p2 rw rootwait  
radxa-cubie-a5e.csc
I changed one line BOOTSCRIPT="extlinux.conf"

Most Armbian boards use the boot.cmd for their bootscript. I found the line I missed in build/config/sources/families/sun55iw3.conf. I cloned a clean build and changed one line in sun55iw3.conf.

Hello, following the steps to add audio support to h3, v3s, a23 modified sun4i-codec to add support for r40, and if anyone else wants to try:

Hi everyone. I have compiled sunxi-next u-boot and activated the SoC internal analog audio codec, now I am testing the mali node. Audio Working!
