USB record and sample rate playback glitches/pitch error.

Hey All, when I record to USB ( internally with the desk ) from the LR of the Avantis I’m getting strange pitch changes and occasional glitches from the recorded files
kinda like there’s a change in the sample rate of the recording. FTR I’ve tried changing the clock from external to internal on the desk and it’s the same.

It becomes really bad if trying to record the LR from a virtual soundcheck from the desks Dante card.

Anyone have any ideas why this would be here?
