UR44 multiple problems


I got my new UR44 the other day and have had a few problems with it since installing.

First of all I’m getting a weird high pitch buzz during recording only on the first input, like this:


It happens randomly every minute or two in Pro Tools 10 and it also happens in Audacity, on both my computers. This brings me to my next problem.

I tried installing Cubase AI to see if it would happen in there, but it says my serial is invalid after getting it from the eLicenser.

edit: it actually doesn’t happen on both my computers after another test. So it’s either a hardware issue or driver issue i guess. Also I’m running windows 7 64bit.

Any help would be appreciated.
