Notebook Audio

Hello!

I've been having sound problems for like 3 months by now. I don't know where to contact someone. I used the HP Support Assistsnt app to leave constant feedback with my issues but never got any update or fix. So I made a fix, but it's only a workaround and it just made me more problems.

In windows there is an audio service called "Conexant APO Agent" (C:\Windows\System32\CXAPOAgent64.exe)

It started to consume insane amount of CPU. My laptop was running very very hot and the fans were always very noisy. However the sound output worked and at some point sound input also worked. Cortana worked etc.

I read online that "Conexant APO Agent" uses high CPU if the audio drivers are written very poorly. I tried to uninstall, install, reinstall audio drivers, force update it.. nothing worked.

Then I decided to do something manual. I renamed that executable to CXAPOAgent64_.exe. Fortunately windows 10 let me. And finally the CPU usage stopped and the sound output still worked sometimes. After playing games it broke tho. I had to restart the computer frequently and run windows audio troubleshooter to "enable audio enhancements" all the time, then another restart is required to start some buffers. Was really annoyed by this. It's a freaking 2019 laptop and the sound system is a garbage...

I tried to do windows updates and try the  CXAPOAgent64.exe but it was high CPU. In the meantime my microphone input disappeared. Cortana and Skype and Discord.. nothing works with audio input now. The build in microphones are unusable.

What should I do to make sound work again? Reinstall the whole windows 10 and start from scratch? Buy a new laptop? Bring the laptop into a repair store?

Also is it okay that the fans never stop spinning? Even if i close all applications and don't use the laptop the fans are spinning. I installed QuickCPU app because the HP applications (including HP Command Center) nor Windows 10 power plans (which are basically got removed from the OS completely) doesn't allow me to control my CPU boost frequency and stuff. I tuned everyting down to minimum using QuickCPU app yet my fans are still spinning.

If you need more information let me know. Also if you know a support channel where someone can contact me, or where I can contact someone let me know.
