This test case is intended to fail, because there is no mechanism to turn off the sound. If the background sound is played (Netscape 7.1 does / Firefox 1.0.6, Opera 7.51 does not) it is to loud to understand the speech output - This testcase should be tested with different browsers.
Three or more accessibility experts.
“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case fails the following success criterion at line 8, column 10: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#visual-audio-contrast-noaudio.
The test case fails the following success criterion at line 16, column 18: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#visual-audio-contrast-noaudio.
Background sound can not be turned off and is to loud to understand the speech reader
The embed element works with MS IE and attribute hidden="true" (tested: Firefox 1.0.6, IE 6.0, Netscape 7.1, Opera 7.51)

The file is valid.
The embed is widely supported but not part of the W3C's DTD for XHTML,
so the file uses a custom DTD to ensure valid code.
