Bear in mind that I'm talking about round-trip: the time it takes for the
sound to go out and come back in again. If only you're interested in the
time it takes to generate a sound and send it out so it appears in sync
with screen action then the output latency is probably about half the
round-trip latency.

In any case, the ear tolerates more latency when syncing to image, because
we are used to sound arriving after light in real life.
