the RME cards can't run with a smaller frames-per-interrupt setting of
64. at 48kHz, thats 2.6msec round trip. any problems above that are h/w
and s/w configuration. alas, there is so much to look at its hard to
even list it all. googling for "linux real time audio latency" will find
lots of stuff to provide you with clues. note that on many laptops, you
will never solve the problems because the BIOS doesn't allow proper
control over IRQ assignments (this is true of my laptop, for example).
