Public bug reported: This happens almost always at "cold" start (VLC not sitting in system tray or has not been used recently); this happens very frequently then vlc switches to the next song in playlist or then vlc drops the stream and re-buffers.
I've tried "default" and "pulseaudio audio output" in audio preferences under output module. Almost identical noise can be heard in a video game called "quakelive", in there it last longer and appears then new map loads. Strange workaround is to open sound settings > input devices > show monitors. Noise goes away after simply displaying "monitors" in sound settings.
