Its been days I'm getting no notification sound on my nexus 5. When I recieve a text, it just vibrates. No sound and then LED light shows that I have a notification. My sound are set to max and everything is ok in the sound settings. Notification sound is set to "hangouts message" but still no sound. I have installed CM 10.2, does it have anything to do with the sound? But sound was working for like weaks after I installed this rom.
