interrupt-drivenからtimer-basedになったという話。なるほどなー。
The PulseAudio sound server has been rewritten to use timer-based audio scheduling instead of the traditional interrupt-driven approach. This is the approach that is taken by other systems such as Apples CoreAudio and the Windows Vista audio subsystem and has a number of advantages, not the least in reduced power consumption, minimization of drop-outs and flexible adjustment of the latency to the needs of the application.
alsaもtimidity -iAもtimer-basedにすれば負荷が減るのだろうか…?
