No[1], but the people writing the audio drivers and DSP firmware absolutely do. Kernel preemption isn't a feature for top-level apps. [1] Actually even that's wrong: for sure there are teams of people within MS (and Apple, and anyone else in this space) measuring latency behavior at the top-level app layer and doing tuning all the way through the stack. App latency excursions can impact streams too, though ideally you have some layer of insulation there.
