Hi Alexander,
You can try to play the sound through HDMI or DisplayPort, the sound quality is better and it's one less cable to manage. If you still want to use the 3.5mm audio cable, try connecting it directly to the motherboard or sound card rather than using the front audio jacks on your desktop (that might be the issue).
