If anybody has an idea of what is going on, please help. When I make a call or get a call, there is no audio coming through so I cannot hear the person at all. I have not found anything in the settings that works to change this. Also during the call there I am unable to click on speaker and when I hit the menu button during a call, the speaker option is grayed out. I can hear voicemail and music fine (media vol turned up). Any ideas because I'm desperate?
