I was having same issue of showing cross on volume button (No audio device is Installed) but now my issue is solved.
try to follow these steps
- Open your Device Manager and Go to Sound Video and Game Controller and then expand it to and right click on High Definition Audio Device and click on Update Driver
- Now a pop-up screen will appear. Click On Browse My Computer For Drivers
- After this a new pop-up will appear click on Let me pick from a list of available drivers on my computer
- After this click on High Definition Audio Device and click Next.
- After this a warning will appear, it will not impact your system simply you can Yes.
- And finally a finished message will appear and you problem would be saved hopefully.
THANKS FOR READING. THIS WAS MY FIRST RESPOND TO ANY COMMUNITY ISSUE. I WAS FACING THE SAME ISSUE THEN IT WAS RESOLVED BY ABOVE MENTIONED WAY. HOPEFULLY THIS WOULD WORK ON YOUR SITE.
