We are already using a RT-kernel and I guess we already did everything we could do on OS changes to achieve a better latency. My doubt is if I can change anything on the snd-usb driver to make it specific to our sound card, aiming an improve in latency, since our pedalboard ( http://portalmod.com/en/index.html) has this sound card fixed and we won't need a generic driver to the usb connection. I'm gonna send an e-mail to the alsa-devel ML, thanks for the advices!
