You're not seeing the sun4i-codec module (which works for sun5i too) because it is build into the kernel.

You should see some audio devices under /dev/snd and /sys/class/sound

While checking things work with Fedora 19 ARM remix for Allwinner SOCs release 1 I did notice that there
is an error in the fex file for the A13-OLinuXino, causing only audio-out to be present, I've just pushed
an updated fex file here:
https://github.com/linux-sunxi/sunxi-boards/blob/master/sys_config/a13/a13-olinuxino.fex

If you save this file, convert it to a script.bin file using the fex2bin utility from here:
https://github.com/linux-sunxi/sunxi-tools

And then overwrite script.bin in the uboot partition of your sdcard with the new one you should
also get a capture device.
