Hello,
My Z2's microphone and speaker have suddenly stopped working.
1) Can't play any sound for music and videos, or cannot hear anything during calls.
2) Microphone also won't work, as I can't record my voice, nor can anyone hear my voice on calls.
3) Also, it won't even recognise headset or earphones 
I have tried rebooting in safe mode, and even repaired with PC companion, but nothing helped Is this hardware or a software issue?
Hi @sankarshan, welcome to the community. I am sorry to hear about this issue
As the software repair using Xperia Companion has not resolved the issue then I recommend you contact your Local support team to arrange a repair.
