I just build my own computer with core i7 4770k, 16 gb ram and nvidia geforce gtx 660 ti graphic card.
then I bought the Motu audio express and connected everything using firewire and at first I do get Normal good sound but then all of a sudden it simply turns into a loud noise and wont work again until i restart the audio express, and it starts all over.
I have downloaded the latest motu universal audio installer, i have tried switching the firewire driver to legacy.
I tried another version of windows 7, and even changing my audio express to a new one in the shop where i bought it.
I am not an expert and hope someone here might be able to help me out.
Here is a link to a video where the problem is shown, just fast forward to 1 minute.
