[LEDE-DEV] Enable sound Olinuxino micro

[sufi al hussaini hassani kamili raheemi]

Hi,

Sound doesn't seem to have been enabled for the sunxi Olinuxino Micro A20 board.

I found this LEDE patch
(https://github.com/lede-project/source/blob/master/target/linux/sunxi/patches-4.4/150-dt-sun7i-enable-codec-on-pcduino3.patch),
which enables sound for sunxi PCDuino3.

I created and applied a similar patch for olinuxino-20-micro, but the
generated dtb doesn't enable sound.

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sun4icodec [sun4i-codec], device 0: CDC PCM Codec-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

# aplay beep.wav
Playing WAVE 'beep.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

I'd appreciate if you could point me in the right direction to solve
this problem.

Thanks and regards,
Shoaib Ahmed.
