Hi, I'm using HP Pavilion 14 and windows 11. I found that my laptop's audio muted and there's no sound output. It occured when I let my screen and sleep automatically. After a while, I open my laptop then it goes wrong with sound output and the laptop must be restarted to fix. It happened several times with text "No audio output device is installed". I've tried to upgrade my audio drivers and update windows.
