Sorry for your issues. We are looking into it and it seems like the problem is that Kodi recognizes the Digi as an analog output. We will try to find a fix for this to put in a later update. Right now, we would recommend using the HDMI output since it also puts out the same signal the Digi does. If you want you can also of course try and implement the fix from your link, but that should be a demanding task. For Kodi, HDMI should be the perfect solution.
