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).
