HP Pavilion Gaming 15-ec0013ur (8NF73EA)
Microsoft Windows 10 (64-bit)

Greetings to the community.
The situation is as follows:The HP Pavilion 15-ec0xxx gaming laptop associated with the windows 10 - 64 update was not observed in build 1909. The problem appeared in assembly 2004!
The problem with AMD Audio CoProcessor drivers (amd - system - 2.89.0.57, .... 58) included in the HP package  sp105486 causes a long reboot (2 - 2.5 minutes) and a long shutdown.
Temporarily fixed the problem by prohibiting the group policy of updating and installing this driver from the update center, and replacing it with the driver from the package  sp100168 - dchu Audio / amdacpbus.sys - from 20,11,19.
Who knows another solution, share the information!

Hi there, where can I find this driver? I have the same issue on 15-ec0001ca

HP Recommended

Hello!
Download a driver - AMD High-Definition Graphics Driver - Picasso Windows 10 v1909 - for your laptop from the HP Download Center. sp100168
Unpack and in the folder  - dchu_Audio. Remove the driver through the device dispatcher, or roll back - if the required driver was installed earlier.

Where would I remove the driver? I'm unable to find it within the Device Manager, and if I try and run the dchu_audio installs from the extracted package it says it is not compatible.

HP Recommended

system devices, then you will see in the list

Thank you, it seems more stable now. The rollback driver version is 1.17.0.91, dated 2019-10-01. Is there another version I should load?

HP Recommended

there is no other. I didn't find

HP Recommended

It may be helpful to install the latest Radeon driver. The Factory Reset option during installation removes all previous versions.

HP Recommended

so tried the same. only replacing the audio driver helps.

I reinstalled windows yesterday. now only the required driver is downloaded from the update center. the system works stably.

AMD Audio CoProcessor drivers amd - system - 2.89.0.57 was loaded from the update center again, another problem appeared, after 20 seconds the volume decreases. Rolled back to 1.17.0.91, this is the most stable one.
