[Qemu-devel] [PULL 3/4] pulseaudio: process audio data in smaller chunks |

The rate of pulseaudio absorbing the audio stream is used to control the
the rate of the guests audio stream. When the emulated hardware uses
small chunks (like intel-hda does) we need small chunks on the audio
backend side too, otherwise that feedback loop doesn't work very well.
