1. Go to the setting and select profile management there. Then select normal profile and with it in enhancement mode select the headset mode.
2. Now first open the mobile and change the handsfree jack and check problem.
3. If the problem still remains after changing the handsfree jack, then we have to use the jumper for a sound IC.

5. Then connect point 2 of the handsfree jack to the transistor as shown in the image.
