iPhone Facebook notification SOUND not working (and others)

Facebook worked great on iOS 5 for me. Sounds all the time.

Yep it did, until FB released their 5.0 app.

Okay now I thought I was the only one!

I get no notification sounds for Facebook. Recently I don't even get a notification at all and have to enter the app.
