BTW, when you plug headphone and the system is not locked, does a pop-up dialogue show and let you choose what audio device you plugged? If it does and you select the Microphone (the rigtmost one), it is expected that the headphone can't output sound.

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.
