CSS2: howto disable audio?

Bert,

I've already raised this issue twice***, but not received a response.

Please could you consider how to disable audio with CSS2?
and let me know asap?

copied to cdf as possibly relevant.

cheers

**CSS & audio

How can the user disable audio?

http://www.peepo.co.uk demonstrates one way that CSS2 can be used to
enable audio on event.

the user may for instance have a screen reader and it would be
confusing to hear both.
unplugging the speaker or turning audio off are not helpful solutions.

apologies if I already raised this issue, I'm known to have a
terrible memory.

*CSS2: howto disable audio?

http://www.peepo.co.uk uses css to provide audio on event.

It would be convenient for some users if a button to disable audio  
were provided.
How might this be done, without using script?

please find attached a reduced testcase, and brief instructions.

cheers

use the relevant nightly build from Camino, Firefox or Opera:
(if necessary place in a temporary directory)

camino
OS X: http://www.caminobrowser.org/download/releases/nightly/

ff
OS X: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest- 
trunk/firefox-3.0a3pre.en-US.mac.dmg
Win: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest- 
trunk/firefox-3.0a3pre.en-US.win32.installer.exe

opera
OS X: http://snapshot.opera.com/mac/o920w_3659.dmg
Win: http://snapshot.opera.com/windows/o920w_8762m.exe

and install an audio plugin such as quicktime:
http://www.apple.com/quicktime/download/

for mouse users: place the pointer over an icon, a speaker icon  
appears, move the pointer over the speaker to play the sound.

unfortunately, for keyboard users, the audio plays automatically: use  
tab or Q/A to navigate.
Is there any way I can improve on this, given that SVG is not read by  
screenreaders?

to change spoken language and text, use Camino,  and change your  
operating system language, then reboot
to change text only, use Opera in XP: tools,preferences, general,  
language...
