Sound question

I have managed to add sound to the home page on my forum that can be heard whenever the home page is accessed, that's pretty good going for me! The problem I have is that I only want the sound to be played after a user logs in, I don't want it heard every time he visits the home page after or it become annoying. Is this possible?

Add the code in a widget. Change the permission for that widget for only for Guests.

Thanks Sanket, it works perfect and is just how I wanted it!
