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!

my task now is to make the kernel's usb audio
driver more appropriate
to our sound card.
What specific problem do you have?
I was hoping that you could give me some
directions on how can I
optimize the driver latency wise, any tips?
For playback, you get lower latency by using a smaller buffer (which
also increases the chance of an underrun).

Clemens
