I've seen issues with the M-Audio Delta 1010 and other Envy24-based boards with 
IRQ steering; I have a laptop with a dock that has a PCI slot in it, and have 
run a Delta 1010LT (same Envy24/ICE1712 chip; and it's the older 'still works 
with Linux/ALSA' version) in it.  

If I loaded the nvidia kmod, the nvidia GPU grabs an IRQ; just so happens the 
PCI slot in the dock and the GPU share the same physical INT line, and either 
the nvidia or the Envy24's driver apparently doesn't handle IRQ sharing very 
well.  With the nvidia kmod loaded, I get frequent ALSA xruns, which glitch the 
audio.  Running the alternative nvidia drivers found in Fedora just causes 
performance to drop substantially; I then get JACK xruns, and still have 
glitches.... This is both with and without the preemption-RT patched kernel.  
But it was an older Fedora; haven't tried in a while, since I installed the 
Delta 1010LT somewhere else and began using a different audio interface on the 
laptop.

To the OP: try putting the Delta 1010 in a different physical PCI slot, or use 
a USB keyboard (just make sure, using 'cat /proc/interrupts' that the ice1712 
entry has its own IRQ and doesn't share with anything else).
