Fix Repeated Windows Device Connect/Disconnect Sounds When Using Multiple Monitors and a Docking Station

Troubleshooting Steps

1. Update the Intel Graphics Driver

Dell has identified graphics driver updates as part of ongoing improvements to display and docking station behavior. Systems experiencing this issue should install the latest Dell-approved Intel Graphics Driver available for their model. A specific driver release was previously reported to improve the behavior on affected systems, but newer versions may now be available.

1. Go to Dell Support and identify your system.
2. Install the latest Intel Graphics Driver available for your model.
3. Restart the computer.
4. Verify whether the notification sounds stop.

Note: Driver version availability varies by system model. Always install the most recent Dell-recommended graphics driver listed on the support page for your device.

2. Update BIOS and Dock Firmware

1. Install the latest BIOS update.
2. Update docking station firmware.
3. Install current chipset, Thunderbolt, USB, and graphics drivers.
4. Restart the system after updates. 

3. Test Display Sleep Settings

As a diagnostic step, temporarily configure connected displays to remain active and test whether the behavior stops when monitors do not enter sleep mode. This may help determine whether display power-state transitions are contributing to the behavior. 

4. Disconnect Non-Essential Peripherals

Remove USB accessories connected through monitors or the dock and test again. Reconnect devices individually to identify whether a specific peripheral contributes to the behavior. 

5. Review Event Viewer

Check Windows Event Viewer > System logs for recurring graphics, Thunderbolt, USB, or Plug-and-Play events that coincide with the notification sounds. 

6. Contact Dell Technical Support

If the behavior persists after completing the steps above, collect the system model, dock model, monitor configuration, BIOS version, and driver versions before contacting Dell Technical Support.
