The XPS 13 9370 may experience high CPU usage. The Realtek WavesSysSvc process may show over 20% CPU usage in Task Manager when the system is powered on with a USB audio device attached to a Dell type-C dock/dongle (including TB16, WD15, D6000, DA200 and type-C to type-A dongle etc.).
To resolve this issue, update the Realtek High Definition Audio Driver from the Dell Support website.
