xperia ZL microphone issue

[sunit1990]

I have xperia ZL from past 1 year(now out of warranty).today while making call i realised the other person can not hear anything,but having checked microphone on diagnostics software or while using on other apps like whatapp or even on ok Google it works fine.I am having kitkat 4.4.2 (.230) update.so please help me with the issue.
Is this software issue?
Whether I should repair my phone?
Or there is something else that can be done?

I also face the same issue. Caller on other side cannot hear my voice clearly. My voice is getting suppressed. I tried after disabling the Noise Suppression, but not helping. Please help me
