Windows 10: Realtek Drivers not present after download & installation, any help?

I'm having issues with a Dell Latitude 7410 audio system. I no longer have sound. I've attempted to update my drivers & uninstall my audio drivers. Realtek audio drivers no longer are present, even after reinstalling AND checking hidden. The volume is always on mute cannot unmute and the PC does not see an audio manager present. BIOS also says Audio Manager: None. Could this be hardware at this point?

Modding Realtek + Dolby Home Theater driver to install on any laptop

So, my laptop (Lenovo Legion Y520) uses the Realtek audio driver, which comes in combination with the Dolby Audio (DAX2) app. However, I don't like the official driver for my laptop much (distorted sound), so I would like to install a different driver. I've tried downloading the audio drivers for some of the Thinkpad models, which come bundled with Dolby Home Theater or Advanced Audio. However, when I install such a driver on my laptop, I do not get the Dolby Home Theater functionality or app. I've also tried editing those Thinkpad drivers' .inf file by adding my sound chip Hardware ID to the list of supported audio devices. But still I do not get Dolby Home Theater.

So, is there a way to mod those Thinkpad drivers (or some other drivers) to get Dolby Home Theater funcionality along with the Realtek Control Panel? I would appreciate any help or suggestions.
