Decide how many times you want your sound to be played. Enter this number into the Loop spin control box. If you want the sound to play continuously, click the Forever check box. Click OK on the Page Properties dialog box. Think twice before you click the Forever check box.
Some sounds can be very pleasing, while others can be very annoying.
Don't forget to save the sounds. According to the instructions, we should save our sounds individually, just like we would our image files. Saving your sound file When you add a background sound file to your web page, it isn't a permanent part of the site until it is saved individually - just like image files. Click the Save button on the Standard toolbar. The Save Embedded Files dialog box will appear and you will see your sound file on a list.
