Hello. I have a T-mobile Galaxy S 5. Recently I tried CyanogenMod 12.1 and several derivatives (such as Resurrection Mix). All share the same problem: during a call, if I plug in a earpiece without a microphone, the microphone in the phone will not work. The other side can't hear me. I can hear the other side though. If I instead plug in a earpiece with microphone (like the one from the phone), everything works. Or if I turn the speaker on from the phone app, the phone's microphone also works.

I remember when I was using the Samsung TouchWiz there is no such problem. Is this a known issue of CyanogenMod? Is there any ticket tracking this issue? Is there simple way to fix?

Thanks!

Hi everyone!

Since hours ago my earpiece doesn't work in a call and the speaker too, but in the others apps it works...
For example, in Whatsapp I can listen voice notes on speaker and on earpiece, listen music, and other things; but in a call, for some reason the earpiece and the speaker doesn't works...

If anyone know how to fix this issue, please tell me.

PD: I am on stock D800 Lollipop Rom
