true, but i take it you get the way CoreAudio is doing
it: it means you
can drive audio processing from a different interrupt source (e.g.
system timer) because you have very accurate idea of the position of the
h/w frame pointer. In CoreAudio, the "callback" is decoupled from any
PCI, USB or ieee1394 interrupt. Tasty.
The price for this is afaik an extra period worth of latency. I'm not
sure this is the way to go. Sure it makes handling of devices easier
that do not generate irq's like pci soundcards do (all this USB and
IEEE1394 stuff), but isn't the price too high?
