Using the 31 May image for opi zero, it installed nicely.
Two issues occur, first one is the missing sound from the 3.5mm jack. This can be solved by adding the audio-codec line into armbiantxt env, which will then allow to use it with alsamixer as well as with the volumio build-in settings.
Second issue is the integrated wlan, that i can not get to work (it works fine with other images like diet-pi or any of the armbian images).
@Paul: stunning job you are doing, really appreciate it !
