I love the latest 18.3 release, it works perfectly.
Currently I have two Minix X8-H Plus units, one in the bedroom using the latest 18.3 which runs like a charm.
But I have a second one that is part of my Hifi system. This Minix is still running a 17.3 build which has a great advantage - it starts up without a TV connected. Nothing is connected to it, only an network cable and an optical SPDIF cable to my DAC. I control it using Kodi Music Remote, a great app from the app store. Like this, the Minix acts as a streamer/bridge with a sound quality as good as high-end streamers such as the Auralic Aries mini.
Problem is, that this 17.3 build doesn't have Wifi. So I'm still looking to get the 18.3 from datrh to work without HDMI connected. Then I can disconnect the network cable and use the streamer/bridge anywhere in my house (and I want it in my bedroom headphone rig).
datrh, if there is any way I can help getting the Minix to work without HDMI connected, let me know. I have the 17.3 one working, I can SSH into it and do anything you'd need. Otherwise, I'm pretty much a noob on this, but can do what you ask me to do.
I know many may want to retire their Minix X8-H Plus devices, or have already done so, but believe me, I'm an audiophile and I've compared the Minix to very expensive streamers and it is a shame to retire a device that makes such a good audio streamer. So if we get this to work, maybe many other owners can make it a great streamer/bridge or sell it to audiophiles who want a cheap and high-quality streamer that works up to 24/192 bit-perfect.
