Thanks for clarifying that.

The H9000 does not do any latency compensation or syncing etc, all of that must be done in the DAW.

Looking into the Pipeline plug-in a bit further, it seems that the ms readout in the top left always displays the round-trip latency of the interface, regardless of what hardware is connected. It looks like when you ping the hardware, it will add that additional latency to the round-trip latency. The latency sample amounts you have reported from the H9000 seem correct.

If you click the little wrench icon in Pipeline, that will display both waveforms and you can line them up manually if the auto button isn’t working (but the auto button should do this correctly for you) – https://youtu.be/6cKMcxpaIFk?t=431
