I installed v4.8.1 drivers as a test, and the audio was delayed by three quarters of a frame. Going back to v6 reset the delay to one frame. In both cases the delay was consistent and repeatable.

I tried two other manufacturers cards, and both functioned correctly in the same chain. The CPU is an HP xw8200 that was used for over a year capturing HD without issue (using another brand of card).
