Almost every game I play has the master audio decreased to 50% or even less, some times even to 20%.

Dunno if it's a difference between over ear headphones vs external speakers or what, but the audio is almost always too loud.

or volume

There is a special place in hell for the devs that force you to sit through some shit before being able to adjust volume... I always have to dart towards my speakers before my eardums implode...
