They are not synced.
No HDA nor HDMI audio devices offer any mechanism for sync.
Thanks Paul for clarifying this, much appreciated! is there a way to
tell which of the two will eventually skip samples? Or would it simply be the
one card whose word clock is slightly late (which I can't really
measure)? Would such a drop-out be reported by jackd(2) in its
"messages"?
Thanks again!
Peter
