Help in activating I2S in KODI plugin.

Installed the Kodi plugin successfully. Only thing is I2S DAC cant be enabled in SETTINGS menu of the plugin. I enable the I2S button SAVE and go out of the menu. I come back and I2S is disabled, which means that my “YES” option for enablibg I2S DAC was not saved. Moreover, my DAC is also not shown as a selectable option in SETTING -> AUDIO menu in KODI. BTW the DAC works perfect in VOLUMIO.
I use ALLO BOSS DAC 1.2 on a RPi3, both Rpi and BOSS DAC powered separately through different power adapters.
Kindly help in activating I2S in KODI plugin.

The problem is probably the current UIConfig file from the latest commit, see the solution here.
