Hi Vincent Christopher
Sorry I'm a little late with my reply.
“Hello, after reading the reply I want to perform the Uninstall update driver step but after checking the sound, video, & game controllers section there are a lot of them and I don't know which one to uninstall, and afraid I will make things worst. I also fear the same thing on uninstalling all devices in the device manager universal serial bus. will it reinstall itself?”
Usually, the basic driver will be automatically installed after reboot. Only two types of drivers can not be automatically installed: 1, notebook-specific drivers, such as camera drivers, etc., this kind of driver you can find in the computer's official website to download the corresponding driver connection. 2, some graphics cards, sound cards can use Windows self-installed drivers, but also can use their official website to provide the driver. If you use the driver provided by the official website, you need to reappear the download on the official website of the graphics card and sound card after uninstalling.
You can open Device Manager, plug in the headset, and check whether there are new devices in "Sound" and "Universal Serial Bus Controller". If there is no new device, it means that your headset is not connected to the computer.
In "Sound", find Realtek (R) Audio, right click to uninstall it and restart.
“I have 191 GB available storage space. is the non-system disk the data (D:) drive? and will it keep my Windows activation key or not? because mine activated using a digital one”
40G of storage space usually refers to the system disc C drive. However, this condition is usually not very precise, so you can try to override the installation first, and then clean up the disc space when it fails.
Overwrite installation is the replacement of system files on top of the original system, and it will not affect your Windows activation status.
“and yeah the earphones still don't work but I did found the Headphones Realtek (R) Audio option on Settings > Sound > more sound options. it says not plugged in even though the earphone is connected rn. Also, it's not disabled”
The fact that you are showing unconnected here means that the headset is not connected to the computer.
Let's summarise the current situation:
You see in "More Sound Options" that the headset is not connected. If you look in the Device Manager, you see that the headset device does not appear when you plug it in. These two phenomena can be a good indication that your computer is not recognising the headset.
There are two possibilities for your computer not recognising the headset: the lack of the underlying driver, or a hardware-level problem that prevents the computer from recognising the headset. So you can first try the above steps to override the installation, or if it does not work. We suspect that there is a problem at the hardware level, such as dust accumulation, poor wiring connections, or even hardware damage. We recommend that you visit an offline shop for testing.
If my description does not match your reality or if you have questions please let me know in a reply.
