For Windows trying to standardize on HIGHEST_PRIORITY_CLASS, mixed with THREAD_PRIORITY_{IDLE,NORMAL,TIME_CRITICAL}. Which maps to {1, 13, 15} respectively. Then trying "Pro Audio" hack with AVRT to get whatever that gives in the 16-31 fake "realtime" bracket for highest.

Linux mapping will be {SCHED_IDLE, SCHED_OTHER with 2 settings of nice} to match. Unfortunately SCHED_FIFO is locked out by default, but if the user blesses the right permissions will get better audio latency. Maybe pause/unpause will trigger auto latency re-adaption.
