My laptop's sound has decreased

[Oz654]

My hp laptop recently had a crackling sound issue but i solved the problem deleting the 'realtel high definition audio device' from device manager and restarting my pc, after the restart windows 10 automatically installed the audio device but i noticed that my laptop's sound decreased a lot. it used to be much higher. 

and i remember before the crackling sound issue when i clicked on sound icon it was saying 'realtek high definition audio device' but now it says 'high definition audio device'

any help?

The Realtek audio driver can be restored.

This looks like a driver conflict between Realtek Audio and the AMD Audio CoProcessor.

Which driver version (Driver) and hardware ID (Details) does the AMD Audio CoProcessor have? Can be found in the Device Manager > System devices > AMD Audio CoProcessor > (see above).

If hardware ID:

PCI\VEN_1022&DEV_15E2&SUBSYS_(can be different)&REV_00

or

PCI\VEN_1022&DEV_15E2&SUBSYS_(can be different)&REV_01

then the driver version should be 2.xx.x.xx, version 6.x.x.xx causes these problems.

The correct driver can be found in the Microsoft Update Catalog.

Install:

Uninstall AMD Audio CoProcessor from Device Manager (remove with software) > Restart > Windows reinstalls a version 2.x driver

You can upgrade this to a higher version:
Download the driver > Unpack it into a folder with an unpacker like 7-Zip > in the Device Manager > Update driver > Browse my computer for drivers > Browse button and select the folder with extracted files from the CAB file > OK > Next > Close

or

In the folder with the unpacked driver files > Right-click amdacpbus.inf > Install > Restart

Right-click on the loudspeaker symbol in the systray at the bottom right > surround sound > click on deactivate (even if a check mark has already been set) should also eliminate the noise, but only temporarily.

 there's no 'AMD Audio CoProcessor' in my device manager so I dont need to remove anything from device manager, right? Could you tell me which driver should i download from the microsoft update catalog?

Without AMD Audio CoProcessor there should be no sound via HDMI... Your computer is a little older, perhaps this is done via other hardware.
