HP Omen 15-dc0xxx Randomly decreases in volume

[HemantSuresh]

Initial Problem

My Omen by HP 15-dc0xxx has a problem where when I was watching a video, It randomly decreased the volume even though the windows display still says 100% Volume. So, I did a couple of things like reinstalling some old 2016 driver and switching Audio Enhancements on and off to no avail.

Restore

At some point I thought it might be something I messed with in the settings by mistake earlier that made this happen. So I restored to an old restore point 2 weeks before any of this started happening. After the restore, it seemed to be working fine. But I started watching a video and the volume slowly decreases until it becomes inaudible again. I don't know what is triggering this. It still says Volume is at 100%.

Additional Information

My Current Windows version is Win10 Home 1909, OS Build 18363.900 installed on 30/9/2019

My Realtek Audio Driver version is 6.0.8716.1

I have Audio Enhancements on because turning it off makes it significantly worse.

I'd say I have  tried everything, but I really don't know. Please help...

Hi @Banheim I deleted the Realtek device as well as it's driver. Then I hard rebooted and when I downloaded the Driver you told me to then tried to install it, the following warning showed up. I still have a restore point for 2 days ago so it shouldn't be a problem going back but I currently don't have any driver installed because that installation has failed.
