In theory, when the device is configured for a specific period size, its
interrupts (and therefore the application wakeups) will arrive spaced at this interval (modulo any scheduling delays).
However, if you're using the dmix plugin, the period size of your application's device will not necessarily be identical with the period size of the hardware device. To see the actual period size, look into /proc/asound/card?/pcm0p/sub0/hw_params.
Would dmix allow me to control this better than pulse audio? (I'm still looking into how to get pulse audio to do what I want.)
