IMHO, faad can not really be blamed here:
* it is keeping up with upstream timestamps (good)
* (presumably) outgoing buffers have correct duration (good)
(that is, corresponding to the number of samples for the given samplerate)

So, the "discontinuity" is inherent (upstream), and it would be detected sooner
or later downstream.  However, if doing playback, the sink would not be so
fanatically picky and allow for some (e.g. 20ms) jitter.  (IIRC) vorbisenc does
not even allow for a (single?) sample variation.  That would practically force
using audiorate or a wavenc/wavparse trick in a lot of cases (and even then
results might not be so good as simply accepting minor jitter that averages
out).

As such, I would expect encoder (e.g. vorbisenc) to be consistent with sink
(and not to start creating discont or whatever if the sink would not).
