New No sound in apps

[dragnus]

Hi,

I've been having issues with MIUI.

In many apps (Viber, Line), the other end cannot hear me. I can hear them fine.

In Viber, usually they can hear me for about 2 seconds, then it stops. In Line, they get no sound at all.

Any help would be really appreciated. I've already wiped my phone twice. And i really need this working.

Thanks in advance.

Edit:
Here are the details.
I have a MI3W running the lastest weekly of Miui. But the issue was present before.
