Assumptions about the hardware buffer size shouldn't be made,
but it seems reasonable to assume that the driver will make
the device work *as if* the buffersize were framesize * periods
if these parameters are set without error. I've never seen any
driver for which this is not the case.
Otherwise there is no point in setting the amount of buffering
via periods at all !
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
