HP OMEN SW/HW ISSUES - keyboard, sound

[MTysonFG]

Hey anyone,

 

I just bought a used HP Omen 15-En0025no. 

My key letter "R" is laggy, not working very often, or not responding at all sometimes. Very frustrating playing SC2 online and your Roaches not comming to w*r.

 

Well, I have already spent a lot of hours by looking for solution. I have also tried to find a solution on my own by unistalling drivers (official ones) and reinstalling once again. All updates done from the side of HP support assistant SW, also from W10 updates side. Nothing of that was really helpfull. It is a really well known issue in the world of HP Omen users, but still no solution or cause of that problem. 

 

Hand in hand with this, I have also issues with volume drop down. It is really sudden, without any reason and there is also no solution in the drivers.

 

Reddit and HP support pages are full of these problems, but non of their advices were really helpfull.

 

Does anyone knows what to do? If it is a HW or SW problem? Any solution?
