tonight I heard distinctly the disconnect and reconnect sound at 6.46 and 7.16.

Have only integrated graphic card with last driver and already changed the hdmi cable.

Hello Bazzu85, 


Thank you for posting on the Intel® communities.   


In order to better assist you, please provide the following: 


1. Run the Intel® System Support Utility (Intel® SSU) and attach the report generated:  

  • Open the application, check the "Everything" box, and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".   
  • Click on the menu where it says "Summary" to change to "Detailed View".   
  • To save your scan, click on "Next", then "Save".   
  • Use the option under the reply window to attach the report to the thread (Drag and drop here or browse files to attach).  


2. Provide the Report for Intel® Graphics Drivers, follow this link

3. Is this behavior happening while the PC is in Sleep Mode or is it turned on?  

4. Have you tried to isolate the problem by disconnecting any extra peripheral? I.e. disconnecting all the not needed USB devices. Or, just disconnecting the HDMI cable from the PC.

Yesterday I tried to rollback to original windows driver and tonight I didn't ear (maybe I was sleeping) the disconnect and reconnect sound.


BTW with driver version (no problem as said before I think):

1. see attached log

2. see attached log

3. the behaviour was happening with pc turned off and video in sleep

4. the usb are not a problem. I use USBLogView to track the usb events


I'll attach soon a log with version.

another question. Why Intel® Driver & Support Assistant software with driver says "No supported driver or software updates are available for your system."?

from site the last driver is



Here are the log with fresh installed

Tonight I check again for disconnection sound with this driver..


Hello Bazzu85,  


Thank you for your reply. 


The Intel® Driver & Support Assistant (Intel® DSA) is mainly used for Intel® products (like Intel® mini-PCs). Sometimes, if you are using a system from a different manufacturer (OEM), the Intel® DSA might not always check the generic drivers that Intel provides, as the OEM systems will use customized drivers. You can try to click "Refresh Results” on the menu on the left-hand side of the scan page.  


Based on what you report, I understand the driver version (you mentioned it is the original Windows* driver) does not seem to have this behavior. However, in the ASRock's website, this driver is listed as the one they provide. Sometimes the OEM drivers are handpicked and include customized features and solutions to platform-specific issues: 


Something else I found, is that the SSU report using the .7926 driver, shows 2 different versions ( and, please check the "SSU-drivers" file attached. To avoid conflicts between the driver, please try doing a clean installation of the latest Intel drivers: 


1. Download the latest DCH drivers and save them on the computer.  

2. Disconnect from the Internet so no new drivers are automatically installed by Windows Update. 

3. Uninstall the driver and the Intel Graphics Control Panel from Control Panel Programs and Features

4. Restart the computer. 

5. Confirm in Device Manager Video Adapters the controller is listed as 'Microsoft Basic Display Adapter' > if not, repeat steps 2 through 4. 

6. If the adapter continues to be listed as ‘Intel HD Graphics’ or similar, and no other Intel Graphics driver is listed under 'Programs and Features' for removal, then it means Windows has switched to a previously installed Legacy driver. At this point we can remove Legacy drivers from Device Manager

  1. Right-click on 'Intel HD Graphics' or similar, and select 'Uninstall Device' 
    1. In the pop-up window make sure 'Delete the driver software for this device' is checked. 
    2. Click on 'Uninstall'
    3. Restart. (Repeat steps 6.1 through 6.4 until the device gets listed as 'Microsoft Basic Display Adapter') 

7. Install the DCH drivers downloaded on step 1. Try installing first the stable version and test, if the problem persists, try the BETA version 

8. Restart the computer. 

9. Reconnect to the Internet.

tried to uninstall all intel driver under device manager using "uninstall device" and flagging "delete the driver software for this device". I had to do this 3 times (7926/8587/8681).

After that I saw Microsoft Basic Display Adapter.

Installed stable 8681 then and now I test this configuration.

(see attached ssu)

I'll get in touch in a couple of days if the problem persist..



after some hours the disconnect and reconnect sound and related event popped out.. ‌‌ disinstalled all driver and now using from windows update.. if the problem persist I'll try the asrock site version of I don't know if is the same of windows update..

I attach the current ssu


Even with the basic windows driver the same problem..

I'm trying the Asrock site driver..

attached the new SSU..

I don't understand why the ssu sais always " Intel ® Graphics Driver Version:"" when the driver version below is different..


Hello Bazzu85,   


Thank you for the information. 


By any chance, do you have an update using the OEM driver 


Based on what you have reported so far, this does not seem to be a driver problem as we have tested different driver versions and they all face the same behavior.  


You may want to report this behavior to Microsoft*, I found some reports in which they recommend to disable this sound: 




  1. Right Click on Desktop screen and choose Personalize
  2. From the bottom panel click on Sounds
  3. Under Program Events, look for Device ConnectDisconnect and Failed to Connect
  4. Choose one option at a time and from the sounds option choose none.  


However, this will not fix the disconnection problem, you can also check the HDMI cable is properly connected, check different ports if your motherboard allows this (double-check with the OEM), check other cables and other displays if possible.

I'm continually testing and with any of the intel drivers (windows/oem/last official) the disconnect and reconnect event is always popping in event ghost.

Sometimes I ear the sound, sometimes no (I'm in another room for ex. but not sure if the sound pop).

BTW as you see in last page of the link you provide, there's a post made by me some days ago..

I tried to uninstall even the monitor driver. I've a BENQ GW2870H.

What I'm testing right in this days is to power off manually the monitor (windows is setted in any case to put monitor in sleep after 5 minutes as before) and this night I didn't see any eventghost log..

the strange things is that the same monitor was used about a month ago with the old builded pc with an amd apu and no problem at all.

As said before I'm continually testing different scenarios letting windows put sleep by hisself or manually powering of the monitor..



Hello Bazzu85,    


Thanks for your reply. 


As you mentioned, you have tested different driver versions with all of them having the same behavior, this shows it is not a driver problem. 


You may want to reset or reinstall the OS as an extra testing, following Microsoft's recommendations:

sorry but I was very busy in last days..

To recap..

turning of the monitor manually doesn't pop anymore the disconnect/riconnect sound..

Luckly my monitor has a auto off function after a minimum of 10 minute of standby, so:

1. after a while windows put the monitor in sleep

2. after 10 minutes the monitor auto power off by hisself

only one time I heard the sound in the time between point 1 and 2. in majority of cases the sound poped after an hour the monitor was sleeping. so now doesn't pop anymore..

I can still attribute the problem to intel driver/motherboard/windows because in my previous build with amd apu (A8 6600k) no problem at all..but I'm not a video engineer..
