Adds an additional buffer. To reduce latency. No, really.
...
Specifically: there's no way to guarantee no overbuffering due to the startup race, other than having QAudioOutput obtain data by pull rather than push. But if it's pulling then that implies an extra buffer. And since the sizes it may pull are not explicit, there's guesswork involved there.
So: no extra buffer => uncontrollable risk of over-buffering. Extra buffer => a controllable risk of over-buffering.

Actually, QIODevice is listed as reentrant. So no need to forward audio.
...
That said, latency is still absurd for some reason.

QIODevice isn't guaranteed thread safe, so use of it is now thread confined.
