Hi Brigitta,

Thank you for posting your query in Microsoft Community.

There are possibilities that not all the drivers may be compatible with Windows 10. However, you refer to the computer manufacturer's support website and check if there is any update on the sound driver and its compatibility with latest operating system (it could be Windows 8.1).

There could be a possibility of any third party software conflict as you have to restart the computer in order to hear the sound. I would suggest you to place the computer in clean boot state and check.

To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a 'clean boot.' A clean boot helps eliminate software conflicts.
