i have a dual core system, so what i'm going to mention may not apply to your situation.

what i noticed is that when i put my second audiophile 2496 into my computer, i heard the "clicks" that you mentioned.

they were random - not really consistent, and sometimes would not happen for long periods of time.

so the problem was hard to diagnose.

what made it even more complicated, was the fact that at the same time as i put the second 2496 in my computer, i also installed a UAD-1express.

i am not sure if the clicks were coming from the UAD or the second 2496.

but it all went away when i switched to using 1 processor for RTAS (prior to this it was set to use 2 processors for RTAS) - so this leads me to believe it was the UAD-1 trying to tie up the processors.

i thought i would mention it, because perhaps it would help.
