After checking I wasn’t going deaf I figured out the left speaker was louder than the right speaker from my PC. I only noticed this on Windows 10 and I have been dealing with the issue by moving the speaker balance more to the right in the Realtek Manager. This is very evident when using Chrome for things like Google Music or YouTube.
This wasn’t ideal because it shift all the speakers to the right and also the volume was a lot lower all round (Not that I crank it up to 11).
I found I had to close Chrome and open it again before this took effect.
