This is a long-standing issue -- I'm off about 3 frames, via Decklink HDMI, with analog out from the monitor looped back to the receiver. The same setup, with HDMI from the gtx card, is in sync.
System audio is also out of sync with UI, by two frames.
Going through something like VLC, sync is frame-accurate, with both system and GTX audio.
OP: Voxengo has a free sound-delay plugin. You can put it in the main output in the Fairlight page, for each timeline, if you don't have a hardware delay available.
