Hi ,
no iam just using the physical outs – no usb involved yet but as you said it i tied it out of connecting usb makes any difference but sadly it doesnt.
Same noise when the h9 is connected via usb.
Heres a recording of the noise ( if links are allowed) : http://www61.zippyshare.com/v/D3uJF9ms/file.html
Its amplified a lot so you can hear it better – in reality its not that noisy but it adds up if it was on every recording.
