How do the audio and video subsystems of standard Linux systems deal with real time requirements?

  Buffers.

  Badly. Only macOS has an architecture to deal with low-latency audio and video properly. Presumably iOS has some of those features as well, but it was on OS X that Apple did some deep architectural changes for proper low-latency audio and video.

    It was admittedly several years ago, but I worked on a voice chat app for iOS and Android, and the behaviour on Android was horrifying. iOS had very consistent and great audio latency (approx 10ms if I recall). Android devices were all over the place; I think the worst one I tested was over 150ms.

  Using the RT Preempt kernel patch, if you care about latency.
