Re: 1.4 sounds.

The context for this is issue 1840
<http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1840>

In the example provided, sound only seems to play in IE, but can be
easily turned off by using the escape key or UA configuration.

If a UAAG conforming User Agent is in use, this is covered by UAAG 3.2
Toggle audio, video, animated images at level 1, but I think Sailesh has
a good point about non UAAG conforming plugins or other embedded content
here though.

Should we consider bumping this to Level 1?
