While it is possible to synchronize the sample clocks of these cards probably by either sp/dif or by wordclock, i do not know if this synchronizes interrupts, though. I don't even know if ALSA has a mechanism to start two devices at the same time (or as close as possible). I suppose that when opening and starting a "multi" pcm device, the two devices are started closely in time. How close is an interesting question. So it's probably a matter of luck, but once started ok, it might work very well. I would love to be proved wrong though :) The other question is: How well does jack for example work with a multi pcm device? Could the userspace nature of pcm plugins possibly interfere with the low latency requirements? Does it "inherit" the SCHED_FIFO scheduling of jackd (in case it was started with -R)? What about mmap'ing and additional latencies? Flo -- Palimm Palimm! http://affenbande.org/~tapas/
