There is a closely related question for windows 7, though 8 has a lot of changes, so I am hoping things may have changed.
My laptop speakers need to be at 100% and still it would be nice if the sound was louder. But I usually run my headphones at about 8%.
The problem is when I forget that I have the volume set for speakers and plug in headphones and start some music. OUCH!!! And it may damage the headphones too.
Is there a way to automatically cap playback volume over headphones?
