Linux Mint audio static

[SystemCrash86]

Hi guys, i am having a bit of a nightmare with this one and i have been pulling my hair out for nearly two weeks trying to fix this issue and finally i decided to ask for help from this great community.

I have a standard Linux Mint installed on my laptop and everything is updated.

The problem that i am having is that there is a loud static noise coming from my speakers whenever my laptop is on battery power.

I get no static at all when my laptop in connected to AC power which leads me to believe it is a power saving issue of some kind but not sure.

I have tlp power saver installed and tweaking the settings does little good.

On battery power though sometimes the static is a bit quieter to the point of stopping completely. So i think great my issue is solved, only for me to load media like vlc or clementine etc and i get the loud audio static again and when i close these windows it all goes quiet again. There is also the loud static type sound when powering on and off my laptop.

 

I am completely stuck. Please i really really hope someone can help
