Oh, I see...
On my side I didn't succeed to run without distortion (but no xruns
strangely!!) with jack 103 or without xruns (with jackdmp) at lower
frames, i.e. 64 samples.
It's weird because I can easily run at 64 samples under WinXP under
heavy cpu load...
I have an Echo Mia first generation BTW coupled with an Athlon XP 3800+
dual-core on a Gigabyte K8U-939 (Uli chipset).
To go back to your situation, I do not know what to suggest and I hope
your problem will be solved soon.

Your AMD
dual-core is not 64 bit?
In my case, I have also an AMD dual-core (64) but I run 64Studio 32 bit
version.
Also, the fact that your soundcard shares an interrupts with other
devices is (I think... correct me someone if I'm wrong) less than ideal.
Is it possible to try another PCI slot, thus giving its own IRQ to your
Echo card?

I have two (32-bit) AMD Athlon MP 2800's (an older Tyan motherboard,
the Tiger MPX). It still performs very well though. I will try
swapping PCI slots, though this seems to be more related to the
software side of things, because as I said when I use just the analog
i/o (the first 8 channels, i.e. hw:0,0) and not the alsa multi plugin,
Jack suddenly becomes ridiculously rock-solid (it's actually *hard* to
get xruns, even running at 64 frames). Such a vast difference in
performance almost has to be software related, probably (as the
previously linked web site mentioned) something clock-related but then
I don't know much about what's going on at the driver level.
