Hi, look in archive of this mailing list, there is a message from me with subject 'Pine64+ HDMI output note' sent at Sun, 16 Jun 2019 09:34:39 +0200. Basically, I used some snapshot, then recompiled newer system from sources, and added line hw.regulator.disable_unused=0 into /boot/loader.conf file. I verified it with fresh CURRENT stable, just this one modification was all needed to get HDMI output working. It was actually working, just line driving circuit was switched off without this line. See message mentioned above for full details. Hope this helps. Milan
