Symptoms

Audio issues on C2422HE, C2722DE, and C3422WE monitors connected to an Intel 11th Gen CPU computer

 

An audio issue has been identified with the C2422HE, C2722DE, and C3422WE monitors. It happens when they are connected to an Intel 11th Generation (or newer) CPU desktop or Laptop. It only happens when the Intel Smart Sound Technology (SST) for USB audio driver is enabled.

This occurs when you connect:

  • The monitor and Intel 11th Gen CPU (Tiger Lake) computer use the USB Type-C upstream cable.
  • The monitor and Intel 11th Gen CPU (Tiger Lake) computer use the DisplayPort (DP) and USB Type-A to Type-B upstream cable.
  • The monitor and Intel 11th Gen CPU (Tiger Lake) computer use the High Definition Multimedia Interface (HDMI) and USB Type-A to Type-B upstream cable.

The monitor appears to have no audio, or the audio lags. This happens once you enable the Intel Smart Sound Technology (Intel SST) for the USB Audio driver on the computer.

Note: The Intel SST driver is enabled by default on these Intel 11th Gen (or newer) CPU computers.
 

This issue impacts any Dell desktop or laptop with the Intel 11th Gen (Tiger Lake) or newer CPU.

For example:

  • XPS 13 9305 Laptop
  • XPS 13 9310 Laptop
  • XPS 13 9310 2-in-1 Laptop
