Sounds to me llike you have the wrong sound card line out setup.

When you plug the USB cable in the computer there should be three 
entries in device manager in control panel once the drivers are loaded. 
One under the "ports" heading which should say "USB serial port" write 
down the Com port number you're going to need it. The other two will be 
under the sound heading in device manager. One Microphone labeled USB 
Audio Codec, the other a Speaker with the same label. Make sure the 
Speaker with the USB Audio Codec label is set active instead of the 
onboard sound card of the computer.

That speaker setting is your line out level from the computer to the 
K3s. The microphone USB Codec is the line in level for the K3s to the 
computer. Both need to be enabled on the PC and levels set properly.

If you have two USB sound cards you need to figure out which one is the 
K3 and which is the computer.

This applies to a Windows 7 and up computer.
