This would indeed be annoying. Fortunately, it’s pretty easy to fix this problem, if your configuration is what I think it is with Yahoo Messenger.
Start up the application, it’ll look like this:

Now, click on the Preferences option in the Messenger menu along the top:

and you’ll be take to Preferences for the application. The second of the options is “Alerts & Sounds” and that’s what you want to check. Here’s how I have mine set:

The key is to ensure that you have “Enable alert sounds” and/or “Showing a message at the bottom right corner of the screen” (or both). If you have both set, then I suspect that your buddy list is messed up and/or your preferences are messed up. In that case, you might try uninstalling the application then reinstalling it again.
Good luck!

My messenger today suddenly stopped giving me alerts when I receive Email. Other alerts still work. Do you have any suggestions?
the above option didn’t work out for me…. as it is default and the sound alerts are enabled but i dont get any sound alert…, i don’t think there is any problem with the sound driver cuz rest of all the software works fine
