I was listening online music without earphone but suddenly audio stopped. Rechecked internet connection. Every thing was fine but no audio.
Connected device with blue tooth of home theatre ,surprisingly audio was available on other device connected by blue tooth.
Got a call, the caller ring was ringing but no voice was heard in normal mode Switching the call in loudspeaker mode the audio was heard but not in normal mode. Audio is also available through yearphone .
Tried to solve the problem by factory resetting but no result.
