Simply put, the RPI firmware does not work with USB audio correctly yet. See this thread: http://lists.puredata.info/pipermail/pd-list/2013-07/103261.html
I keep looking for fixes, but the way USB is handled, the only way for it to work without dropouts is to have *nothing* else plugged into the usb bus and ethernet disabled ... sucks.
