Two nights ago, I noticed that I had several missed calls and messages that I didn't know about. I observed that my phone was not making any sound when calls or messages were coming in. Earlier in the day it had been ringing and giving other audio alert. I checked to ensure that the profile is set to Normal or even Loud. I have tried opening Slacker Radio and Pandora, and it will say that the station is playing but there is no audio. I have tried restarting, taking the battery out and replacing it, and have tried to adjust settings but nothing is helping. Anyone have any suggestions how I can get my audio back? My phone is my alarm clock so I really need to figure this out! Thanks!
