MacBook Pro 2020 Speakers/Volume Issue

Hi Guys/Gals

So recently I've noticed when listening to music on my 2020 MacBook Pro the music will start playing loud and then drop down a noticeable amount of volume after about a second or so, it also does this when listening to music through earphones too.

Is anyone else experiencing this? Hoping I can get some help on this one as it's quite annoying given the whole reason I bought a MacBook Pro was for my music and DJ software!

Thanks in advance for any help/tips/guidance.

Nathan :)
