Subject: The behaviour of winsound.Beep() seems to differ between different versions of Window... 
X-Git-Tag: v2.5.3c1~124
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=549171e1ab84e9812965050d25ab2e25dbb8d90a;p=python

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.
