I have an Asus K52Jc and in sound configuration there is no independent sound device for the headphones, and so there's no way to have independent volume for speakers and headphones.

Is there a way to have independent devices? Or is this hardware specific?

lshw reports that I have an "Intel 5 Series/3400 Series Chipset High Definition Audio".

If I'm understanding you correctly, it looks like that the device driver for your headphones isn't installed - Can you check to see if it's showing as installed?

card 3: Headset [Logitech G930 Headset], device 0: USB Audio [USB Audio]
  Subdevices: 0/1

This is what my output looks like, and I can have separate audio output/input for both speakers and headphone

You have USB headphones, right? I want independent volume for normal 3.5 jack headphones. –  amfcosta Apr 21 '12 at 16:59
