I bought a lumia 720 phone 2 months back. It was working fine till yesterday. I am facing an audio issue wherein i am not able to play music through the loud speaker. But when i use my headphones, i am able to hear the music. Also when i am not able to hear the other person nor the phone rings when i call someone (both with and without earphones). But when i try the same with the loud speaker on while calling someone, then i am able to hear the phone ringing and even the person's voice on the call being picked. 
Please help me with this issue.
