The Pacamara uses the audio interface as its clock source. In Kyma, it will display whatever the USB audio interface presents as the clock source choices. If the DSP window in Kyma shows "Internal" it means that the LIO8 is not presenting any choices for the clock source (or that they do not publish a name for the clock source).
I have noticed that at 96K, there seems to be clock sync dropouts. Any solutions to this?
Can you please test whether this might be an out of realtime issue by switching to the built-in 3.5 mm audio outputs temporarily?
