I searched the archives and found only a couple of references regards
this without much  more info than the documentation provided in the
header.

I have tested on several hosts and none seems to have it implemented
including AULab.

Perhaps AudioUnitProperties.h misses to mention its only applicable to
output AudioUnits?

As a workaround, is there a way for an AU to get a reference to the
AUGraph it is connected to?
This way I could iterate thru the graph collecting latencies and
calculate a persentation latency for mine - based on buffersize, out
device safety buffer size, latency etc...

is there any other way?

tia,
I.
