Skip-free audio and video playback is a fundamental expectation for many - if not most - Linux users. Given the importance of this feature and the increase in hardware performance over the years, one would think that the audio latency problem would have been solved some time ago. The recent posting of (and mixed reception for) the "RealtimeKit" mechanism shows that this issue remains open, though, and that we are still short of a consensus on how it should be solved.
