Logic Pro 9 - I/O Safety Buffer? | Logic Users Group
https://logic-users-group.com/threads/i-o-safety-buffer.2255/
Phew. So finally it does appear that AU Lab reporting 24+24 samples safety buffer is not quite right but not far off and yes Core Audio does impose a safety offset that "apparently" varies from device to device - but it (Core Audio) does impose an offset for every device that uses it and that's all of em except Digi TDM AFAIK. Kind regards

objective c - core audio: is zero equivalent to silence ...
https://stackoverflow.com/questions/13565904/core-audio-is-zero-equivalent-to-silence-only-for-pcm-audio
PCM is the raw encoded sample. All 0 (when using signed data for samples) is indeed silence. (In fact, all of any value is silence, but such a DC offset has the potential to damage your amplifier and/or speakers, if it isn't filtered out.) When you compress with a lossy codec, you enter a digital format where it is not trivial to just add silence.

figure for output latency (sans D/A and mixer) = working buffer size (ASIO) + safety buffer + offset In case of this MOTU driver it is: 64 + 64 + 16 = 144 samples, 128 + 128 + 16 = 272 samples and so on. For vast majority of other drivers, that safety buffer is fixed (either like 32 samples, or 1-2 ms) regardless of working buffer size.
