Can I use headphones with sound audigy 2 card?

Absolutely not. In many parts of the world, using headphones with Audigy carries up to
fifteen years in prison, and in one Asian republic, carries death by caning.

Seriously: you can use headphones with any device, program,or pci card that
is supported by your system. Your computer has headphone outlet, which is why you need amplified speakers...it is not too powerful, but it enough for headphones, which are actually just very little speakers anyway.
