Alert sounds turned off

[buymeaniphone]

All my alert sounds stopped working on my PowerMac G5. Even audio on videos on line and my email alert sounds dont work. I can play music using iTunes but thats it. I checked System Preferences and everything looks fine there. Any advice?

Your prefs look like this?

And check the Output tab. That all looks OK too?

yep, looks exactly the same

Well, I'd start by removing ~/Library/Preferences/com.apple.systempreferences.plist
Then restart.

Unfortunately, this will reset everything you've changed in your System Preferences.
