Thank you for information, gentlemen.

The frequency difference may be caused by firmware, even with all clocks locked 
to TCXO.

The only reliable way is to look at the actual codec clock source.
In Orion I it was a 14.360 MHz crystal connected to the main codec
(page 6 of Orion I logic board schematic).

Has anybody dared to look at Orion II logic board, or at least the schematic?
