Why do you say it's not related to pools ? When using fixed size buffers, we
should always use a pool to allocate. Those are parameters that could be passed
to our local pool if downstream does not have a pool. But also, sometimes the
pool won't be NULL here. It's just that for audio it should have the semantic
that if possible, you use that extra space. If not, you'll be better allocating
smaller chunk (otherwise it's a waste).
