I agree. Developing our own audio subsystem has been
forced by circumstances, but if libao now fulfills all our
needs, we should use it instead. That would be a big

That sounds like something connected with buffering
settings. From what I've seen, our latency requirements
are quite special compared to other applications in the
desktop world, so I think the important think is whether
libao allows us to negotiate these requirements with the
target audio system (like the various buffering parameters
in Pulse Audio etc.).
