These are instructions on how to add a startup sound to Mac OS X.
Step One Launch Automator from your Applications folder.
Step Two Click the New Document button.
Step Three Select Application from the list of document types then click the Choose button.
Step Four Drag the Run Shell Script action from the list off Actions to the workflow pane on the right hand side of the window.
Step Five In the text area, type Afplay followed by the full path to the sound file you would like to use as a startup sound. You can also just type Afplay then drag the sound file into the text area.
Step Six To make sure your sound file plays correctly, click the Run button at the top right of the screen. If you receive a warning that the application will not receive input when run inside Automator, just click OK.
Step Seven Once you've confirmed that the sound plays correctly, choose Save from the File menu.
Step Eight Enter a name for the application that you will remember, choose your Applications folder from the Where dropdown menu, and click Save.

For those of you having trouble with the "May only Specify one file to play" message…
I did some testing and figured out that, if the file's pathname has a space in it, it doesn't work… e.g. '/user/name/folder/song.mp3' seems to work,
but '/user/name name/folder/song song.mp3' does not… at least not on my MBP : )
I am about to delete this app. The f@€king ad that you have to "wait" until it allows you to continue is infuriating at the very least. As much as I like this as a source of news - I have better things to do with my time.
You must have a paid version - the ad stays for at least 8-10sec on my phone - often in some corrupted state - it took me at least 30sec to get to reply to your comment.
this command should disable the chime (haven't tried though):
sudo nvram SystemAudioVolume=%80
or you can run this AppleScript when logging out:
osascript -e "set volume output volume 0"
