Hi Friends,

I have a need to have an audio player kick off things at various points of time through playback of an audio file. I'm trying to hack aplay as a proof of concept.

If I understand correctly, the asynchronous handler seems to do what I want. I hacked in a handler to aplay and it works, but not quite like how I expected.

Oh, forget about async handler. It's a horrible hack, and in principle, never guaranteed to work.

We really need to put DONT_USE tag to async handler APIs...

I counted the number of times that the handler got called, and thought that if I multiplied that by the period time that I'd end up with the total audio length but that doesn't seem to be the case. I was under the assumption that the handler was called once per period.

I must not understand the relationship of the asynchronous handler and period_time. Does this make sense? Am I going about this all wrong?
