The laptop is totally new. It's delivered 2 days ago. Everything is fine until I find the sound issue.
The sound is working as I turn on the laptop, but if I restart the laptop, the sound is gone.And if I shut down the laptop completely, then turn on the laptop again, the sound is working again.
Sound device is Conexant SmartAudio HD CX20722, OS: WIN10 home 64-bit
I have tried re-installation of the audio drivers which is download from the Dell website, reinstall WIN 10, and all other kinds of suggestions. But sadly they are all failed.
I am really appreciated anyone can help me with that. Thanks so much.
