Realtek HD audio driver is important if you want to use all features of Realtek. I have no way to test this here so I leave the rest for you to find out.

The Audio manager gives control of many extra settings that are not in Windows 10 such as speaker configurations, Sound effects and Virtual Surround settings.

Now, head to the recording tab to check your headset microphone volume. Realtek’s onboard sound card device drivers include an Audio Manager that is packaged with the installation of the Codec. If not, then it is simply a matter of telling windows that you want sound through this device instead of the other device used before. Make sure the microphone device is set to your headset microphone in the audio inputs section. In the case that you do find your headphones there, it should have a green circle with a tick inside it like the screenshot below telling that is the device being used for outputting sound.

Chances are that you just need to install proper drivers for it. If it is not there then Windows is not recognizing your headphones and you have to find out why. You should be able to see your headphones there. If you right click your speaker symbol down to the right on your screen and choose Playback devices, you will be given a list of devices which can output sound, like the screenshot below. In the case that you have a built-in sound card on your mother board, something most consumer motherboards have now a days the case might be that Windows is still trying to output sound through the built in sound card instead of sending the music through your headphones.
