Hello!

I don't have hyperthreading, atleast there's nothing about that in bios.
It's a dekstop computer though.
Hmm, alarming! I do use both USB keyboard and USB mouse. My soundcard is
also USB. I do have alot of other devices plugged in aswell to my USB. Is
there any way I can fix this, other then getting "real" plugs for the USB
keyboard/mouse? Like I said, there's still a couple of devices that uses
USB even if I get rid of the mouse/keyboard.

@ Jeremy "So the xruns are not completely gone? And what if you force the
Lexicon to only use 2 ins and outs with -i2 -o2? Could you also post your
jackd command (run JACK and check with ps -eo cmd | grep [j]ackd)":
No, not completely gone. Running a project now that has ~70% cpu load
(never goes above that), and that gives atleast 4-5 pops each second. It's
not inaudible, but it's very prominent. That command told me something like
"/some/path/jackdbus auto" which I figure isn't of much help? I start jack
through Cadence, so I don't know how to extract the command from that
really =(.

I will try forcing the use of 2 ins and 2 outs!

Also, the MIDI issue turns out to atleast 1st be a problem with either the
keyboard or the actual soundcard. I suspect the keyboard, it has been
messing with me before. Gotta crack it open and take a look.... =/

Anyway, thanks for all help! I really need this working, if the pops can go
away for this I'll have a golden production environment =).

Cheers,
Gabriel

This is not great, both USB are on the same irq. do you use a USB mou=
se or
KB? That could cause problems. If you have the plugs for mouse and KB use
them even if you need adapters. Some bios let you tell the bios not to set<=

irqs for the USB or video. That might help as Linux seems to be a bit more<=

inteligent at doing it. In the end usb1 and usb2 may be hardwired to the
same irq. That probably means you can only use one of them.

Laptop or desktop? in either case a USB card may help.
