Context and environment...?

Is there by any chance sample rate conversion going on somewhere?
(Hardware or software; usually behaves in about the same manner.)
Since buffer sizes in most environments need to stay fixed, and usually
also have further restrictions, this tends to affect buffer/callback timing.
As a result, input-to-process and process-to-output latency drift over
time, and pop back (buffer drop, or extra buffer) on a regular basis.
