Aha. _That's_ the problem. OK, I won't be able to use the OSS emulation, because I need to chunk in multiples of 5ms. Thanks! > If you have problems actually, let us know :) Well, it took quite a while to figure out how the trigger() and pointer() hooks were supposed to work for a non-DMA device. (DMA is of limited use on this device because it can only interact with on-chip SRAM.) When I have my ducks in a row, I'll post this driver along with some theory of operation; it would probably be nice for the next poor sod if it made it into the documentation.
