One problem is that some motherboards and sound card drivers can only be installed after a bus driver is installed, and then they can make noise. Check whether there are other things with question marks or exclamation marks in equipment management.

Sometimes the system confidently installs the driver automatically, but it just doesn't make any noise. You can do it.

Uninstall the sound card in the device management, scan the hardware changes, and then manually specify the location of the driver (there is a sound card driver in the CD attached when buying a computer), ignoring the prompt that the system prompts that there is no digital signature. Let's see if it works.
