Firstly thank you for such a good and progressive operating system. Here is the problem: Normally, sound works perfectly when the output device is speakers. It is also works when I plugged in the headphone on PC when the system is on. However whenever I try to plug in the headphone when the system is locked (on locked screen) the headphone does not work anymore even I restart. But it works when I try to plug in it when the lock screen is not active on next day. It is not working right now. The list of Output Devices in the Settings: - Speakers - Built-in Audio - Headphones - Built-in Audio When I select headphones, the sound is gone at all. Also yes, I tried to use headphone on another devices and they work perfectly. I will put all informations that you might want. Please let me know if you need more information. I am also not sure if I chose the right output device. Thank you.
