Better than any internal audio card

I have had one of these for over a year now. Best thing about this card is the ability to have more than one input working at the same time. Windows DRM since Vista has disabled the ability to have Line in and Microphone working at the same time. Since I have two computers, one connected to line in on this and a microphone for talking to friends it does exactly what I need. I have purchased several audio cards and spent hundreds on some that couldn't perform as well as this one.

Works as promised!

This is an excellent audio addition with a 5.1 or 7.1 speaker set. I can work much longer when listening to music through this unit.

powerful and simple

I broke my headphone jack on my laptop and this product fixed all my problems quickly with no effort other than to plug it in and change a couple of settings in the sound options. Very happy customer right here!
