My Music Code has stopped working

I've been adding music to the forum for Birthdays & events & up 'til today it's been simple.
I add this code
<embed src=?wav hidden=true autostart=true>
<noembed>
<bgsound src=?wav>
</noembed>

Into the Display..homepage, generalities, homepage message, using the HTL editor.

Today I've done it & can hear the music clearly when I'm in the admin panel, but not on the forum .
Any ideas guys ???

...after struggling for hours a friend pointed out that all other members could hear it.
The probler, was my recently upgraded browser.
