Hey,

recently I've encountered very similar problems with MP3 file decoded via
filesrc. The pipeline was roughly the same, my app basically takes some audio
sources, and mix them with adder. Adder always has at least one fake source
(audiotestsrc playing silence) to keep pipeline running and it whole pipeline
is forced to use 44.1KHz wherever possible via capsfilters.

That problem encountered only with MP3 files that were recorded in 48KHz.

Opus uses 48KHz, too.

So combining all this information plus beforementioned log I am starting to
think that this bug is not related to Opus, but audioresample. Or combination
of different sources where some are 44.1KHz, some are 48KHz, resampled to 44.1,
and then mixed by adder.

Is it possible be due to the fact that adder don't care about timestamps?
