if so probably need an amp!

He's correct, you need an amp. Sound cards are usually not powerful enough to drive high impedance headphones such as the DT990 Pro at high volumes.

Even a basic little amp would probably do the trick. Something like one of the Little Dot amps or a Headsave Classic (if you can find one), Rega Ear, etc...
