it's unfortunately not so easy to fix like other consumer cards. since ice1712 *always* needs 10 channels x 32bit samples and its max. buffer size is limited to 64kB, *at most* you have 0.1 or 0.2 sec buffer size. when the task is switched for longer time than that (which can happen easily), you'll get dropout. one of the workaround is to start the application with the higher (RT) priority, so that it gets scheduled at the right time. also, using a sound server running with the RT priority, other apps can run with the normal priority.
