Does any streaming input utilize the buffer that AIR does? I only see the buffer setting in the device settings for the AIR inputs, not the others (RAAT, Spotify Connect, etc). But I'm guessing that all streaming inputs must have some kind of buffer or cache to avoid drop outs. Does anyone understand how different non-AIR inputs are processed?

Each protocol/driver has is own approach regarding buffer. Don't bother about buffer, unless you have a problem, and changing buffer is helping you dealing with that problem.
