Our Motorola One (XT1941-4) has a curious audio fault: No audio is heard during a voice call when using a mono earpiece with microphone, connected via the 3.5mm jack; although the other caller can hear what is spoken.
On the other hand, using a stereo headset with microphone yields no problem at all either way.
Also, using the same mono headset, audio from music and video playback can be heard without problem.
What is happening here? Can this be fixed?
We've tried rebooting the device but this makes no difference.
