On output, when possible, your app should schedule outgoing packets in
advance. As little as 5 ms in advance may make a noticeable
improvement. Scheduling more than 100 ms in advance is probably not a
good idea, unless you make further calls to flush previously-scheduled
events when you stop etc.
As an aside, could you tell us how far ahead the built in MusicPlayer
schedules packets? Reason why I ask is that I have recently changed
parts of my app and am now getting a short pause when performing some
actions. This never happened before.
