Known issues

I have a Lenovo 310 Ideapad running Windows 10 version 1909. Some have reported replacing the Conexant audio driver with the Microsoft HD audio driver and then waiting several days for the regular Windows Update process to install version 2004. Does this actually solve the problem? For example, when I start to install the Microsoft HD audio. Depending on your sound card or the current version of the sound driver, you can face some sound problems in Windows 10. This time, users of Conexant HD Audio noticed sound issues after the upgrade to Windows 10. If you’re one of them, I compiled a few workarounds for this problem. Let us know which one worked for you.

This table offers a summary of current active issues and those issues that have been resolved in the last 30 days.
