As a first check, I ran my 96kHz sine-wave files though
sndfile-resample, which is an example application that comes with
libsamplerate. In every case, the files produced by sndfile-resample do
not have the clicking which implies that libsamplerate is OK.

Then I took a close look at the clicks and they have resemble a sinc
function, which suggests that the error is in filling the input buffers
to libsamplerate.
