OK, but did you check the status of the sound controller in Device Manager when this occurs?
To get to Device Manager in Win 10 from the desktop right click on the Windows Start button, left side of Taskbar, select Device Manager link from the drop down box. When Device Manager opens, scroll down to Sound, video and game controllers, click on the + symbol to expand the list and see if there is a red cross or a yellow exclamation mark against the sound controller entry. In your laptop it is a Conexant controller I think. Right click on the entry, click on Properties and then view the info in the Device status box in the General Tab.
If there is a yellow cross next to the sound controller entry, try installing the latest Asus Win 10 audio drivers from this link. Ensure that you install the ones appropriate to your audio controller. Also take heed of the Notes: regarding driver installation found near the top of the webpage in the link provided.
