I've been using an Octamic II and an Audient ASP880 with my UFX+ for quite a while, probably over a year.

I've had no problems with sync until a few days ago, when I noticed that the Octamic II was no longer synced. I unplugged and re-plugged some cables, and then everything was working fine. Except the problem came back a few days later, this time with the Audient not being synced. Again, I juggled some cables, the ADAT 1 and 2 lights on the UFX+ came on, and all seemed well. Then, today, the Audient was unsynced again.

I did the unplugging and re-plugging thing again, but now neither the Octamic II nor the Audient will sync. I've tried different light pipe cables, different BNC cables, and different T-splitters. I've tried putting the splitter on the Octamic and terminating the Audient, and I've tried putting the splitter on the Audient and terminating the Octamic. I've tried connecting only the Octamic (terminated) and only the Audient (terminated) to the UFX+ word clock output. No ADAT lights on the UFX+, and no sound from the inputs of either the Octamic or Audient.

The flashing light on the back of Octamic (beside the ADAT output) goes off when the BNC is connected. The green light on the front of the Audient goes off when the BNC is connected. But no lights for ADAT on the UFX+ and no sound from either device.

I dug out an old Behringer ADAT that I don't use any more and hooked it up. It reports "locked" on its front panel, but the UFX+ ADAT light doesn't come on, no sound comes through (like the others, no response in TotalMix), and like with the others the Settings app shows sync only with MADI.

The UFX+ seems to be working fine otherwise. It plays, and the analog inputs work fine. I also have a 12mic connected via MADI, and that works fine.

Please help! I now have sixteen inputs that don't work. I've pored over the manuals for all three devices without finding anything to solve the problem. I fear it's a problem with the UFX+.

Thanks in advance.
