I've newly installed a desktop system with dual

windows/ubuntuStudio and discovered something exiting.
If I play around with ZynAddSubFX in Windows, I can adjust the card to
64 frames 96000KHz and play with 1,5 ms latency without any kind of
sound glitch or interrupts at all.
If I try the same with UbuntuStudio and jack I get a lot of X-runs as I
play, in a serious situation it's no good, especially as I'm beginning
to use effects in and out of my Multiface in real time for example guitar.
Now that I discovered that my card is fully capable of playing with
extreme low latency I'm not quite satisfied with running 20ms or more in
UbuntuStudio or any other Linux DAW.
Is there anything I can do to tune my jack installation to obtain lower
latency and more stability with my card, so far I haven't had any luck
tweaking the jack settings.
How are you using Jack, specifically? Is your kernel real-time? I have
a similar setup (Windows and Fedora/CCRMA) and HDSP worked out of the
box for me in Linux. Granted, I don't use the card at 96K, though.
