Hi :)
OT:
Dunno why your Layla shows up as two independent sound-cards, however,
AFAIK when using a sound card with an ADAT device, just the optical
cable is needed, there's no need to sync by an additional word clock BNC
cable, as long as all cards are connected by ADAT.
IIUC there never ever will be perfect sync between cards using different
AD/DA converters.
My setup is based on a RME HDSPe AIO + a Behringer ADA 8000. IMO the
Behringer isn't a good audio device, OTOH at least my Behringer ADA 8000
is good for frying eggs. Some time ago I repaired a power supply for
another Behringer device, because it gets broken by undersized
semiconductors, that costs around 2 Cents.
Anyway, if I (would) use my ADA 8000, it (would) work(s) with jack, so
your trouble might be related to the issue, that your sound card does
appear as two cards.
Regards,
Ralf

not correct. sync just requires a shared sample clock. any two devices with
word clock connectors and a cable between them can do this.

If so, I should get a RME Word Clock Module (WCM). That won't make the
ADA 8000 a better device, but at least phases between the RME and the
Behringer (or some better ADAT devices) would be clean.
Just for the record. SPDIF and ADAT can sync two or more e q u a l

FWIW, I'm currently using a RME Raydat w/ word clock module. I have two
pres going into a RME ADI-8 QS Converter, and 8 pres going through a
Focusrite converter. Not sure I'm doing it right, but I simply put the
wordclock connectors from raydat out to QS in, and raydat out2 to focusrite
in. Seems to be syncing (and locking) just fine. No problems with jack,
either.
Not sure what I'd do if I needed to connect a 3rd converter, as there are
only two wordclock connections on the raydat.

I can confirm this. Syncing via ADAT can be problematic, and in
particular the B. AD8000 is quite sensitive to this - I'v got a
few of them that will fail to sync if there is a signal only on
one or two channels and 'digital silence' on the others. Using
the WC input instead there's no problem.

"ADAT clock has some issues, in my experience."
I experienced that the analog IOs of a RME HDSPe AIO and a Behringer ADA
8000, synced by ADAT only, can be used together, with THE exception: If
channels should be in sync, e.g. a right and left channel, than those
right and left channels must be from the RME or the ADA 8000 only, a mix
of both does result in unclean phases.
However, the OP doesn't have this issue.

The world wide web gives different information regarding to T connectors
and the "loop"/"thru" feature of some devices :S. I tend to trust the
most worse scenarios ;), IOW believing the world wide web, neither T
connectors, nor a loop function provided by some audio devices should
work with a 100% warranty.

ADAT clock has some issues, in my experience. S/PDIF
clock is better.
Word clock is best.
That sounds similar to "my girlfriend is a little bit pregnant (,but she
isn't completely pregnant)" ;).
Once upon a time Germany won the "Eurovision Song Contest" with a song
called "Ein Bisschen Frieden" (A little bit of peace).
Soooooooooooooo,
our girl friends simply are or aren't pregnant. [whatever] clock does
the job or it doesn't. There's peace or war, but not a little bit of
peace.
Between the lines there's some useful information ;), OTOH the info is
that >>clock by ADAT and SPDIF is "more worse" than clock by
"wc"<<?! Is
there any warranty that any kind of clock is available to do the sync
perfectly?

Ralf
