For those looking for perfect alignement, you can use this one loop of 500hz sine wave :
Put this wav in front of the DI-signal and use it for alignment, works like a charm.
Using SPDIF, I get an audible shift so this is very useful to align perfectly.

Could you, or anyone, clarify this process? I think this method would work for me but am unsure of the best way to use the sample.
