Dell Optimizer Displays a Notification When a Zoom or Teams Call is Active, and the Call is Muted

Dell Optimizer users may receive a notification with the message "Your voice quality is poor, try moving closer to the mic or move to a quieter location" when on a Zoom or Teams call and the call has been muted (Figure 1).

(Figure 1. A notification with the message when on a Zoom or Teams call)

The third-party application (Zoom, Teams) is muted by the user, but the audio driver is not aware of the mute state of the application.

The hardware state of the microphone has not changed, and the microphone remains active.

The audio driver detects variance in the input signal from the microphone and has Dell Optimizer display the message (Figure 1).

Laptop users may enable the hardware mute feature by pressing the F4 key (Figure 1). Doing so mutes the microphone at the hardware level. The audio driver will not receive any input from the microphone, and the notification will not be triggered.

Alternatively, the notification can be turned off by setting Voice Quality Monitoring to OFF in the Dell Optimizer Audio page (Figure 2).
