To add to this, I am wondering, because of the higher latency of some of
the newer USB AIs, if it would make sense to have a jack backend that
allows jack to run at a lower latency than the AI. So the AI would run
64/2, but jack would run at 32/2 or less so that there was time to offload
processing on more cores/threads.
