You are waiting probably because no one has the guts to be blunt: adding sound to navigation is so unprofessional and tacky that it is usually obvious to most as "cause to pause" to re-think the idea ....
unless your site is completely done in Flash, the "effect" is lost entirely if presented to visitors alone without complimentary action (and Flash add-in sounds are of a
much higher quality as well).
IMO
Second part of it is the adding of sound to links is an easy procedure, and when asked, telegraphs to all that you still have much to digest about a core process: the
Tutorials on
LINKING and
MENUs clearly show the small tick box and
BROWSE function to locate and add a /
WAV file to the action of hyperlinking. It is especially visible vis the
NAVIGATION and
ROLLOVER icons in Blue Voda (lower left ).
When you get done configuring the sound in the
PROPERTIES of your object, then simply upload your sound file to the
public_html/ directory of the site so it can be located via the link and played as designed.
If these instructions are not up to par, simply do a Search of the Forums to find others (located top of every Forum page).
