I just installed Windows 8.1 Pro on my MacBook using Bootcamp. Before doing this, the startup sound that gets played whenever you turn on the MacBook would play through my earbuds if they were connected. However, after installing Windows 8.1 alongside OS X using Bootcamp, it always plays the sound through the laptop speakers.
I don't understand why this is happening.
It's a fairly trivial issue, sure. But if I'm in the library turning on my MacBook and happened to have left it at a high volume, I'd rather not have it make a loud, obnoxious noise.
