The behaviour of winsound.Beep() seems to differ between different versions of Windows when there's either:
a) no sound card entirely
b) legacy beep driver has been disabled
c) the legacy beep driver has been uninstalled
Sometimes RuntimeErrors are raised, sometimes they're not. If _have_soundcard() returns False, don't expect winsound.Beep() to raise a RuntimeError, as this clearly isn't the case, as demonstrated by the various Win32 XP buildbots.
