I've newly installed a desktop system with dual boot 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.
