I don't know if this is the new code that was added recently.

If its the old stuff then it absolutely is not zero jitter. You're
confused about the difference between "real time", "low latency" and
"jitter". The whole problem of the old code is that was absolutely
"deliver it as fast as possible" and that is precisely is what causes
jitter.
