Ensure you are running the latest version of iOS.

1. In the FB app, tap the options icon on the bottom right.
2. Swipe all the way down to the bottom and tap on Settings
3. Tap on Account Settings
4. Tap on Sounds
5. Perform Happy Dance

If it's still not showing up you'll need to report it as a bug to the Facebook iOS developers.
