[Bug 28723] Sound stutter in Rage when emulated windows version is set to "Windows 7" (XAudio2 -> mmdevapi sound output path)

A quick question from "just curious" series: on a native system Core Audio API
in shared mode implements a mixer. My tests show that on native system it
operates in 10ms chunks of data (as observed by GetCurrentPadding). I don't see
any signs that current implementation of mmdevapi in Wine has it's own mixer
(either witch emulates behavior of native OS and drains data from buffer in
10ms chunks or really does some mixing duties). Does it means that design
decision when implementing mmdevapi for Wine were to use mixing capabilities
from downstream subsystems (ALSA dmix, PA, hw mixing in sound card)?
