I have a external usb soundcard. When i stalled my new keyboard witch have the same thing built in the keyboard my sound was totally distorted.
now i can only use 3.5 mm again too get a correct sound.
 
Most likely you can't have two sound devices plugged in at the same time as they are conflicting with each other.
Obviously you can't manage without the keyboard so the USB sound device will have to go, or get a standard keyboard which doesn't have built-in sound device.

Don't understand why you bought a USB sound card anyway if the computer's built-in 3.5 mm sound jack works.
If the reason was to get better quality sound with more features, you could install an internal PCI sound card and plug your speakers in to that. Then you wouldn't need the USB sound device anyway.

If it's not a device conflict problem, it could be that there's just not enough power available from the USB ports to drive both the USB sound card and the keyboard at the same time, so try a Mains Powered USB Hub and plug the USB sound card in to that.
