WaveRT pin stream: exchanges the frames its device's tick hands it with its stream's ring.
moves the frames elapsing with this tick between the WaveRT buffer and a ring
A render endpoint's buffer feeds the ring, a capture endpoint's is fed from it, each wrapped at its own end. The ring's producer index is shared, its consumers are not: this endpoint keeps its own read position, so control clients reading the same ring take the same data rather than each other's.
