Thanks for the reference, this helps.

Thats fine on one site, on the other NTP is not always "audio time" to
synchronize to Audio clock.
BTW.: We kind of "miss-used" OSC for audio streams now Version 2.0:
- https://git.iem.at/cm/aoo and tested is within http://vrr.iem.at/
with still some issues, so we want move forward to V3.0, so this discussion is
welcome trying to implement in ESP32's.
