What kind of problems do you have ?
I get nasty xruns everytime, my system accesses the disk (appr. every 3-4 secs). I posted this to the jackit-dev list and Paul Davis replied stating that jack is intended as professional (sic!) solution with very low latency, that he's using SCSI therefore and he didn't seem to care a lot. BTW: Increasing the period size doesn't help. I'll give it another try with a low latency patch applied to my system (Debian with 2.4.18). Maybe that fixes it. But for installations or concert situations I need a reliable system which works unattended for days and therefore prefer the direct way, where pd just grabs the driver.
The ALSA code in pd is just missing the direct way, that is, sending non-interleaved samples.
Are you sure, ALSA can handle this? I thought, ALSA doesn't work with uninterleaved samples. If that's the case, I'd much prefer the direct way of course.
Who can help in that respect? ALSA documentation is still hardly more than nonexistent and the API far from straightforward.
