It's not that simple. It's not cpu power that counts, but, mostly the
latency.

So, if i read this correctly, you share your wct4xxp IRQ with some hdd
controller and usb?
Try to move all of the traffic to another one wct4xpp card, and try to put
this card with shared interrupts temporarily out of the box.
Also: might be a good idea to disable software echo canceling.

Note: i've have got very similar issues some years ago, but it was (that was
suggested by Digium) a reason of using a clone card, not orginal Digium's.
