I will try to reproduce your scenario.I have only one monitor. When I boot I have no sound, unplug hdmi and plug it again and sound starts working. It would be interesting that sound works without needing to replug cable (using only one monitor).
Right now the hardware I usually use in the NUC7 Dawson Canyon is sitting in my NUC8 Bean Canyon.
It probably won't be until tomorrow.
In the meantime, test on High Sierra to see if it is a new problem in Mojave or something that was also present in 10.13.
Also, you could enable FakePCIID_Intel_HDMI_Audio.kext by changing FAKH to 1 in SSDT-NUC7-DC.aml.
