So I listen to music on Pandora and Youtube quite a bit on my PC with some headphones. I noticed one day that when playing music on iTunes that when I play it on max volume I get max volume, it's really loud, but when I play music on the internet no matter what browser I use at max volume the sound from the internet section of the volume mixer is only half of the max. In other words if speaker volume is 100 and so is the internet I only get 50 from both.
Maybe I didn't word it right. In the volume mixer both volume bars are set all the way up yet the output never actually gets close to the max. So lets say chrome is set at 100 (max) the output is more like 50-55.
When I play music through iTunes also maxed at 100 in the volume mixer the output is also 100 and is significantly louder than any music played through the browser. So if iTunes can reach the actual max volume of the system why can't the internet browsers.
