"In particular, laptop/notebook users have often been out of luck in this respect. Most laptops do not come with 5.1 outputs (much less 5.1 digital output) and the internal sound options usually aren't upgradeable. Thus, those who have wanted a professional sound option for their laptops have usually be left less-than-satisfied. ASUS wants to change all of that with their new XONAR U1 Audio Station. This USB soundcard aims to provide high quality Dolby Digital audio as well as EAX and DirectSound 3D support for systems where other sound upgrades aren't an option. A slew of other features is also provided - let's see if the Xonar can deliver on all of this."
