In Windows 10 the volume can be per app. So right click on the speakers in the task bar and "Open Volume Mixer." Now push all items to the top then pull the one on the left to where you want it.
I can get good sound from my speakers from my computer off of the Internet through songs and videos, but I can't here anything anywhere on the Internet. I have tried several places: Youtube, Facebook, Yahoo, etc. I can't hear a thing anywhere.
