Hello Kevin, thanks for the results!

Ok, that looks good, so it's about a Delta 1010 card which uses the
snd_ice1712 kernel module.

There you go, looks kinda busy there. Looks a bit like the situation on
my notebook:

16: 320312 30 IO-APIC-fasteoi uhci_hcd:usb3, mmc0,
firewire_ohci, jmb38x_ms:slot0, eth1, nvidia

But I manage to use to run a FireWire audio card just fine on this
notebook so there's still hope for your Delta 1010 ;)

Here it's sitting on it's own interrupt so it'll probably run fine

Nice, 4 cores and hyperthreading? Or really 8 cores? But the ondemand
governor might be a culprit (I say *might*, I'm still not 100% sure in
how far the ondemand scaling governor affects JACK's performance).

>> More information on tweaking your setup:

Then also install rtirq (or rtirq-init) and check the section in the
Wiki on rtirq. Make sure you put snd_ice1712 in the list of softirqs
that need to get prio. Put it first or second in the list. This will
free it from the burden of having to share its hardware interrupt with
all the other stuff. You could also try moving the Delta 1010 to another
slot, if possible a slot with a free IRQ. that would be the best option.

Best,

Jeremy
