LED indicator for mute sound isn't working

[Mitke97]

Hello,

After last uppdate to version 1803 led indicator for mute tone is not working, but led indicator for casps lock is working. How could i resolve this problem? Please help, this is very disturbing because this is my new laptop. It is HP 15 with intel i5 7200u.

I have tried to troubleshot, reinstalled keyboard and reinstalled sound drivers and it is still not working.

Hi,

Try the following.

Download the Realtek HD Audio installer on the link below and save it to your Downloads folder.

https://ftp.hp.com/pub/softpaq/sp83501-84000/sp83941.exe

When done, hold down the Windows key and press R

Into the Run window, type devmgmt.msc and hit enter.

In Device Manager, expand Sound, Video and Game Controllers.  Right click the Realtek device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

When complete, restart the notebook.

When windows has reloaded, open your Downloads folder, right click on the Realtek installer and select 'Run as Administrator' to start the installation.  When this has completed, restart the notebook again and let windows fully load for a few minutes before checking the function of the mute led.

Hi,

Try the following method with a slightly earlier revision of the audio driver package.

Download the Realtek HD Audio installer on the link below and save it to your Downloads folder.

https://ftp.hp.com/pub/softpaq/sp79501-80000/sp79991.exe

When done, hold down the Windows key and press R

Into the Run window, type devmgmt.msc and hit enter.

In Device Manager, expand Sound, Video and Game Controllers.  Right click the Realtek device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

When complete, download and reinstall the Chipset driver on the following link.

https://ftp.hp.com/pub/softpaq/sp83501-84000/sp83858.exe

When the Chipset reinstallation has completed, shutdown the notebook.

Unplug the AC Adapter and then remove the battery. 

Hold down the Power button for 30 seconds. 

Re-insert the battery, plug in the AC Adapter and start the notebook.

When windows has reloaded, open your Downloads folder, right click on the Realtek installer and select 'Run as Administrator' to start the installation.  When the installation has completed, restart the notebook one more time and again, let windows fully load for a few minutes before checking the function of the mute led.

Should i downgrade to the last update and see if led is working?

Hi,

It may be worth checking if the Realtek installer package on the link below helps first.

https://ftp.hp.com/pub/softpaq/sp87001-87500/sp87168.exe

Additionally, install the latest version of the System Event Utility on the following link.
