sms sound not working

[nursemm05]

I did a search and found a cab for email sounds not working and tried that but it didn't solve the problem. When I get a new sms the sound fails to play. It's checked under sounds and it plays there but not when new sms comes in. Doesn't matter which file I chose either. I can chose one of my own in storage (used to work), move that file to windows (never worked) or a stock on in the windows directory already loaded on the phone (doesn't work either). any suggestions?
