Yes, if it is a clocking issue it should show everywhere when you do this simple test:

- create a new session
- hit default to your system setup
- add 18 mono audio tracks to your session
- make sure all of them get discrete inputs from analog 1-8, adat 9-16, spdif 17-18
- route them to your monitoring output
- record enable and hit record
- record for a minute and take a look at the waveforms in the edit window

You should see spikes in regular intervals on every track at the same position. Height of the spike does not matter, nor does it matter whether your dummy session is recording silence or something more useful. For testing purposes silence is better and spikes more visible.
