unfortuantely both cards can't work with such a small period size. i don't think any consumer card works with 64 bytes per period. > > Basically, we are trying this 'cos we want the card to raise interrupts > as frequently as possible. > > Is this a h/w limitation of ymf724 card or is there any way we can get > to reduce the period size on a ymf724 card to around 64 bytes ? no. ymf724 produces interrupts with a fixed frequency (256/48000 = 5.333 msec), independent from the buffer or period size.
