I bet this is just the way the hardware behaves. It probably takes a few seconds to turn on its amplifiers and audio path when USB streaming starts.
If it doesn't happen in other OSes, then most likely those OSes continuously stream audio to the device even when it is unused. The workaround would be to do the same, e.g. use pulseaudio and disable suspend-on-idle, or use JACK, or something along those lines that always keeps the device running (with silence when no app is using it).
