I'll do more testing later today. I could see some issues with networking or interfaces like S/PDIF or HDMI, where the receiver needs to relock. But for local playback we should be fine. You will still send zeroes out as soon as the sink-input is created, and there'll be an interval before the first valid sample is provided by the application. -Pierre
