If you check the manual for these monitors, I think this would explain
the phenomenon you're experiencing:

Generally speaking, if you're hooking up devices that expect line-level
audio signals to a consumer PC audio card, you'll want to set the volume
level of the output to between 75 and 100%, then adjust the volume
controls on the speakers themselves to achieve a comfortable listening
volume. This will help reduce interference / cable noise as well.
