I have been using mi-1 earphone for my lumia 920 quite a while. But just after the update to wp8.1, the earphone no longer works. The right side is totally dead.
My earphone is still in a good condition with other devices. I am sure that is a sole problem of the phone.

Haha try this.. Plug the earphone into the jack, put the one that is not working in your ear, play music, then gently start pulling the plug out of the jack, but not completely, just till you hear a sound..
Tell me if this works

I blew air into the jack and rotated the plug around inside the jack. Turn the volume to full then back down again. Unplug, replug, unplug, rotate, etc. Repeat and you should eventually get results.

This works, but to fix it so you can use your headphones normally, restart your phone. This happened to my 925 and I restarted it and it was back to normal, then it happened again so I restarted again and it has not happened again since.

Ok! When I have this problem again I will try this
