XPS 15 9500, cracking noise on WiFi activity

Since I updated the audio driver of my XPS 17 15 9500 to the latest version yesterday (Realtek USB Audio DCH Driver - A18 - 21.19 MB - Optional - Install). I hear cracking noise coming out of the speakers whenever the WiFi card is transmitting. Of course this becomes worse the more traffic is ongoing. From a HF perspective, this is definitely an EMI / poor hardware design issue with HF-energy coupling into the audio inputs/amplifier. Can anybody confirm the issue?

I fear it's not only related to Wifi activity alone.
