Good to know I'm not the only one.
Are you on firmware 8.02?
I use an Apogee Rosetta -> MOTU 828mk2 -> Logic X (OSX 10.9.4)If you are able to, what's your audio interface and which operating system are you on? If you're unable, same question?
The reason I ask (and have posted about it before) is that I am unable to use mine successfully via s/pdif hooked up to a NI Komplete Audio 6, on anything from El Capitan to Sierra, on multiple Macs. In a nutshell, Audio MIDI Setup thinks it's getting 44.1k from my AX8 when I select External Sync, and there appears to be nothing I can do to change that.
Just trying to see if this is something that's unique to my unit, or a problem with the KA6, or something else entirely (including user error). A user in a recent thread had s/pdif problems with the Focusrite Pro 40 and Scarlett 18i20, but was successful with an Mbox Pro 3. What's your experience?
Me too.
I have the exact same problem with my new Scarlett 18i20 Gen2. With my Mbox 3, S/PDIF sync was not a problem (same Macbook Pro same OS (Sierra), Q 0.02). But with the 18i20, I can get it to sync no matter what I try, but... the one thing I discovered is that when everything is hooked I turned the tuner on and suddenly the thing synced!!! Once I passed audio the lock was broken...
I know the quality of S/PDIF vs Analog Out is pretty much the same, but i'd like to work with S/PDIF for it's convenience as it's one stage less of A/D D/A for tracking/reamping.
UPDATE: IT IS DEFINITELY THE AX8.
I hooked my TC Electronic Nova System (also at 48KHz) with the same cable and all, and locks/syncs just fine, so it's something with the AX8. Hope @joe rogers and/or @FractalAudio chime in and take a look at this.
Seems like we're at an impasse with this... Most devices work with the AX8's spdif, some don't. Strangely, it seems like even within the same brand, some do and some don't, like the Scarlett 18i20 that seems to be pretty much incompatible. And alas, my Komplete Audio 6 falls into that category too, which is a bummer cause I specifically got it so I could have that extra channel 5 & 6 to hook up the AX8.
For whoever is interested in getting an interface and using the spdif with their AX8, I thought I'd summarize this thread here. Not a complete list obviously, but the findings of this thread so far:
COMPATIBLE:
Focusrite Saffire Pro 14
Focusrite Scarlett 6i6
MOTU Ultra Lite
MOTU 828Mk2
ESI - U24 XL
SPL Crimson
UAD Apollo 8
UAD Apollo Twin
Behringer FCA1616
Presonus Firestudio Mobile
Presonus Studio 192
Mbox Pro 3
Apogee Ensemble
Audient iD22 (with coax to opto adapter)
INCOMPATIBLE:
Native Instruments Komplete Audio 6
Focusrite Scarlett 18i20
Focusrite Saffire Pro 40
I don't think the available data allows to put together this list. As mentioned before I do successfully use an NI Komplete 6. There are obviously more conditions that influence a successful connection than what your list implies.
Using s/pdif with ESI - U24 XL on my Macbook Pro with latest OS X. No issues at all.

Hello Johan, I would appreciate if you can please assist me, as I have just bought an U24XL interface, and bought a coaxial cable for digital connection between my interface here going into my DAT-30 Tascam. The Tascam is set to 48khz, but it keeps changing to 44khz. In the U24XL software, all things are set to 48khz even my Logic DAW. But still. If You can please help me figure this out. Any instructions and advice really appreciated as I am losing the enthusiasm for this device. BEST / brian
Thanks, Johan, for coming back. I have pulled out a second Tascam that I had and the same results, however, I discovered that from the U24XL panel, when changing the sample rates, the 32khz and the 44khz change accordingly on my TASCAM. It's just the 48khz that it shows for a split second and then jumps back t 44khz again on my Tascam. The signal is showing on my Tascam meters, so I can guess the digital out of my U24 and the cable work well. However, I noticed that when I highlight DIGITAL from the U24 panel the sound becomes erratic and stuttering, perhaps this has to do with the optical out of the U24? -That sounds like it would be something for Tascam support if it keeps changing. My understanding of spdif is that it’s just a bit stream and we have to configure each device to pickup the stream correctly. i.e. there’s nothing in spdif that sends any form of metadata like: “currently sending 48khz 16bit” so we can’t just plug it in and have it work automatically. So if the U24XL is picking up the data correctly, it’s doing it’s job and the problem would lie elsewhere.

Also note: the ESI has a panel software as you know, so even in there 48 is set, and in my DAW and on my MAC Audio, Midi settings. It's just my both TASCAMS not accepting 48 with digital cable hooked in. When the digital slider is set to analogue on my Tascam, no problems there. 48 shows and stays there. BEST/BRIAN
Yes, it's a very good clear sound, I sometimes think that this unit deserves more attention. Regarding my tech query, was thinking that perhaps continuing to record at 44khz via my digital connection, which works fine, is a very good idea after all.No worries, the only time I’ve heard any weirdness is when there’s been a mismatch in frequency with the U24. I never use the U24 control software, I only ever look in the Mac Audio/Midi settings panel and make sure it’s set to 48khz digital there and it’s always worked brilliantly.
