  Jennifer DeleonSep 3, 2025
  If the sound coming through your Dell Headsets appears to be at a lower or quieter level when you open the system control panel for audio devices, close the control panel before using the headset to listen to music or audio. Accessing the system control panel temporarily switches it to call mode, but it reverts to music mode once you leave the control panel.

  If you experience issues when muting or unmuting the microphone using the Windows system control panel settings, use the dedicated mute button on your headset to control the mute or unmute feature in Teams and Zoom. If that doesn't work, click the mute control on Teams and Zoom. Also check the headset connection mode – audio receiver or Bluetooth, connect using the audio receiver because headset buttons don’t work when connected through Bluetooth. The Human Interface Device (HID) Telephony controls mute or unmute feature on Zoom and Teams.
