a while ago i ran ardour a couple of times with the m-man audiophile,
which shares the central ice1712 chip with the delta series. there were
spurious strange discontinuities in the recorded signal then, but i
haven't found out what caused them - might be they were unnoticed xruns.
iirc there were interrupts with a very small number of frames available
on one stream, and >= full frames / cycle for the other, which should
not happen at all with linked ALSA-streams (duplex setup) on this chip.
however for one i haven't run ardour or jack in a while now, for another
ALSA has evolved, and for yet another i have just seen the card perform
flawlessly at 16 frames / cycle with different code.
