"Messaging:New text Message" sound not working :(

Hi all,

Whenever i get a new text message, the phone does not notify me by ringing ringtone or SMS tone sound or audio alert, nor vibrating the device when there is any incoming text message or SMS message.. This is happening with new ext message or SMS only..

I have checked settings-->Sounds&notifications. I have checked the play sound option.. Still its not workin..
Please help..

Thanks in advance
