I have verified my sound drivers via system information / device manager, and they are determined as up to date. I have no unknown or drivers marked with a yellow triangle.
Maybe I just hit a row of videos with low audibles on youtube?
EX: YouTube - Good Size: The Pineapple Song
BTW, I found this song trying to identify lyrics for someone, but you have to admit it's a little bit catchy.
It's only spiking my sound meter to 50% at most.
