HP Envy x366 laptop sound randomly goes up and down, as well as crackling noises.

[will_80]

I purchased this laptop and ever since I have had issues where the sound is randomly decreases and increases. Also I am sometimes getting crackling noises. I have tried all the ideas posted on the internet, e.g. remove and re install the sound drivers, and the laptop has just had a factory reset and re installed all of my programs. I am using Windows 10 Version 20H2. 

System Spec

AMD Ryzen 5 4500U with Radeon Graphics

8GB RAM

AMD Audio Device & AMD High Definition Audio Device & Realtek High Definition Audio

Is anyone else having similar issues?. as this. I'm not sure if it's faulty hardware, bad sound drivers, or has it got anything to do with windows 10. 

I would be helpful if anyone could help with this issue, as it's driving me crazy when i'm using my laptop to watch films, listen to music etc... and then the sound becomes so quite. 

Thanks....

This is something to do with AMD drivers. Please

   (a) Uninstall Audio driver

   (b) do a cleanup using following information/fix:

                https://drivers.amd.com/drivers/amdcleanuputility.exe

   (c) reboot machine

  Machine will re-install Audio driver for you.

I have followed the advice of Banhien (Thanks) and ran the AMD and then used the HP Support Assistant to reinstall the drivers. Hope this fixes the issue and the fault does not return.
