Awareness | unDUSB Volume Control in Zoom

Gain insight into how to use unDUSB Volume Control with Zoom.

Updated at May 18th, 2023

Information


In cases where the custom Attero Tech USB Audio v4.59.0 driver cannot be installed, the following workaround will allow volume control in Zoom Rooms. (Inability to install is most typical in SurfaceHub and SurfacePro devices as they require special administrative rights.)

The unDUSB has unique volume control in that the output signal must be handled by the application as Windows System Volume has no effect.

In the case of Zoom, the software volume control utilizes the System Volume rather than direct control from the application.

The following workaround will allow users ability to lower output volume from the application to a suitable level from the Windows PC running the Zoom software. 

Procedure

  1. With Zoom running, right-click the Sound icon in the system taskbar
  2. Select Open Volume Mixer from the list
  3. Click the Device list in Volume Mixer to ensure the unDUSB is selected
  4. The application volume slider may now be adjusted from this window and closed when desired level is set.
