Hi,

Have you checked if there is a listing for "other devices" in Device Manager to see if the sound controller is there?

Have you selected Device Manager > View > show hidden devices, to see if it is listed there?

If it is listed in either place right click on the entry and select Update driver and follow the prompts and then check if it is shown in the Sound, video and game controllers list in Device Manager.

How did you prove that it is a driver issue and not an audio hardware issue, did you try the HP hardware diagnostics option in BIOS see user manual p.44?

完成的

Also check control center > sound devices and make sure its outputting to the correct device. After updates windows tend to change sound settings. If that doesnt work contact hp and ask for driver help
