They probably adjust the incoming / outgoing buffer sizes (and therefore the audio delay, since it's live) to account for packet loss.

They might also prioritize traffic depending on how full your buffers are.

I can only assume Youtube and Netflix do similar parameter tweaks to optimize their video delivery based on the connection (totally filling the buffer to a max size all the time would waste bandwidth, but if the client has lots of packet loss they need a larger safety net).

Right, looks like we're up to maybe 6 parameters. The claim was dozens which i take to mean at least 24, possibly 36 as the lower bound.
