Sometimes, my phone plays sound (both music and voice calls) only through one earphone. In such cases:
- Unplugging/re-plugging the earphones doesn't fix it, including a different earphone set.
- Restarting the phone does fix it.
Is this a known issue? What is the cause of it? How can I avoid this state?
OS: Windows Phone 8.1 version 8.10.12359.845, but happened in previous versions as well. Phone: Lumia 920, with included earphones.
