selct play calibration tone from your meter menu until you see all your output meters showing tone, then put you pvw in local and hold the record button down, if both meters respond then your cabling is correct.
If not then trying swapping the input cables around, if the other needle now moves then you have a cable / avid issue, if not then it is a vt issue. I haven’t looked recently but there may be routing options in the pvw menu settings.
Then let your sequence play as normal and press the record button again to monitor incoming audio, if both needles respond then you need to check track selection in your digital cut tool.
As I recall the audio mix button on the front of a pvw only effects monitor out not input.
