My laptop upgraded from Windows 7 to Windwos 10.
And it worked well for a while.
But yesterday it got a new Windows 10 update and started to update the OS automatically.
The update took a long time.
After update, it seems okay but I found the audio function can't work.
It shows error icon on the status bar in the right-bottom corner.
I click the error icon and it launched the diagnostic program.
But this program can't fix it.
I checked the device manager and there is no any error for audio device.
But I also downloaded driver and installed it again.
It still can't fix it.
Please tell me how to fix this issue.
