The issue arises when the user’s system repeatedly plays the device connect/disconnect sound when the monitor of his system is powered on/off. Before proceeding, make sure no device (like a USB hub or speaker) is attached to your monitor (as the PC may try to connect to that device and thus the problem). Also, check if changing the cable (connecting the PC and monitor) and its type (e.g., if using HDMI, then try DVI) sorts out the sound problem. Moreover, it will be a good idea to make sure that all the attached devices to the system are properly inserted and seated. Last but not least, check if performing a cold start of your system solves the sound problem.
Solution 1: Change the Monitor Settings
The connect/disconnect sound may be a result of the wrong configuration of the monitor. In this context, editing the relevant monitor settings may solve the problem. The instruction may not be the same for all users.
Solution 2: Update the Windows and Drivers of Your System
The repeated sound issue may arise if the Windows and drivers of your system are outdated as it can create incompatibility between the essential OS entities. In this context, updating the Windows and drivers of your system to the latest releases may solve the problem.
Solution 3: Edit the Playback Settings
The connect/disconnect sound may emerge if your PC is continuously trying to route the audio of your system to the sleeping monitor (which is set as the default playback device). In this scenario, disabling the monitor in the playback settings of your PC may solve the problem. If that did not do the trick, then enable all the devices in the Playback tab of the Sound Control Panel and set the monitor as the default device. Now, set the speakers/headphones as the default device (as per your liking) and disable all the devices that are not essential. Then reboot your PC and check if the monitor is working fine.
Solution 4: Uninstall the Problematic Applications
The issue at hand may occur if an application on your system is continuously sending requests to the sleeping monitor (or playing the Windows Hardware Insert.wav file to notify about its notifications). In this context, uninstalling the problematic applications may solve the problem. The Daemon Tools, Discord, and Pidgin (a chat client) applications are known to create the issue. For illustration, we will discuss the process for the Daemon Tools.
Solution 5: Reinstalling the Display Driver
The repeated playing of the sound can be a result of the corrupt (or incompatible) display driver of your system. In this case, reinstalling the display driver may solve the problem. If the issue persists, then check if using an older display driver solves the problem.
Solution 6: Edit the Power Options of Your System
The sound issue may arise if the power options of your system are not properly configured. In this case, editing the related Power Options (for example, disabling the USB Selective Suspend) may solve the problem.
Disable USB Selective Suspend
Disable PCI Express Power Management
If the issue persists, then either you set the sleep timer of your PC shorter than the monitor timer (so that the PC goes to sleep before the display) or set your monitor to not go to sleep.
Solution 7: Disable Power Management of the HID and USB Devices
The issue may arise if the system’s power management of a device is hindering the display modules’ operation. In this context, disabling the power management of the HID and USB devices man solve the problem. If the issue persists, then check if uninstalling the USB Billboard Device (if present) resolves the sound issue.
Solution 8: Edit the System’s Registry
If the issue is still not solved, even after attempting the above solutions, then editing the relevant Registry key of your system may solve the problem. But keep in mind that the mentioned key may not be available to all users. Warning: Advance with extreme caution and at your own risk, as editing the system’s registry is a proficient task, and if done wrong, you may cause everlasting damage to your system/data.
Solution 9: Disable or Remove the Problematic Devices
The sound issue could be a result of a malfunctioning of a device attached to your system. In this case, disabling or removing the problematic devices may solve the problem. Once the problematic device was found, you may try one of the following:
Clean the device/system’s port and reattach the device.Disable the problematic device (right-click on the device in the Device Manager and choose Disable).Replace the problematic device with a working unit.
The following types of devices are reported by the users to create the issue: If the issue persists, then you may set the Device Connect and Device Disconnect to None in the Sounds tab of the Sound Control Panel (till the issue is resolved) or simply unplug the monitor cable. You may also manually power off the monitor till the resolution of the issue. You can also check if performing an In-Place Upgrade sort out the sound problem. If even that fails to sort out the problem, then check if using another graphics card, that is compatible with your monitor sorts out the problem.
