I observed one difference between ioreg's for the:
for the working one (Sierra version):
IOAudioEngineClockDomain = 0x4178f00
for the problematic one (Mojave):
IOAudioEngineClockDomain = 0x737973
I wonder if this clock value difference could be the trouble with coreaudiod failing to work.
I figure out why the audio didn't work after the update.
There was in the log something like:
localhost kernel: (AppleSystemPolicy) <AppleSystemPolicy`AppleSystemPolicy::logExecutable(char const*, char const*, int)> log-executable mig callout failed 0x10000004 (path: /Library/Audio/Plug-Ins/HAL/InstantOn.driver/Contents/MacOS/InstantOn responsiblePath: /usr/sbin/coreaudiod isExecution: 0)
And I observed that coreaudiod was quarantined and after boot it wasn't launched.
Once that I delete the old content from /Library/Audio/Plug-Ins/HAL/ and I reboot the audio panel and audio was present again.
