Crackling sound HP 17-ca1176ng

[Maxim95]

Hello everyone I have a problem with the Realtek sound drivers on HP.

After some time of operation, the laptop freezes slightly for a short time after which the sound becomes crackling.
I tried to change the device driver to "High definition", then the crackling disappears. But in this case, after a few seconds of idle time without sound, the driver switches to power saving mode (turns off the sound card) and when the sound signal reappears, the sound card turns on with a loud click, which is very unpleasant.

I also tried disabling the AMD High definition driver, which doesn't help.

I tried changing the power saving mode, which also doesn't help.

I even reinstalled Windows, which was not successful.

This is terrible! Realtek has the latest driver from 2020! And there are no updates!

Does anyone know a solution to the problem, or alternative drivers that don't cause problems?

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.
