I can say that I've definitely seen cases where if you configure a
device as the "default" capture device in PulseAudio, then pulse will
continue to capture from it even if you're not actively capturing the
audio from pulse. I only spotted this because I had a USB analyzer on
the device and was dumbfounded when the ISOC packets kept arriving
even after I had closed VLC.
