Solved!

A Conexant audio device could not be found. The application will now exit

HP Recommended
ProBook 470 G4
Microsoft Windows 10 (64-bit)

As APM-Raymond said but upgrading the information

I have a ProBook 470 G4, Windows 10 Pro 64bit that had the same problem. What I did is.

  1. Download the latest Audio driver from HP site https://support.hp.com/us-en/product/hp-probook-470-g4-notebook-pc/10477368/document/c05519670 according to your type of HP.
  2. Extract it to the ProBook / EliteBook / etc and install it.
  3. Reboot after the installation.
  4. You will still get the error after login again. No worry.
  5. Go to this folder C:\Program Files\CONEXANT\SA3\HP-NB-AIO, run setup64.exe.
  6. You will be prompted to UPGRADE, go ahead.
  7. Then reboot the laptop again.
  8. After login, the error is gone. But it is not done yet, you have no sound on the laptop.
  9. Simply go to the taskbar and look for the Speaker icon, click on the Troubleshoot sound problems and the problem will be fixed.

 

Hope this helps, it resolved my problem after I tried many different ways.

 

 P.S. I have tried several times but finally I did it!

Dear all,

 

For all of you having problems with the Conexant audio device (I had the same problems within a year...which is not that so good for HP and they have to find a solution in this regard) I will write you the steps you have to take in order to solve your problem. The last time it works from the first try but previously I had to do several times.

 

Thus, here what you have to do if you have an HP ProBook 470 G4, Windows 10 Pro 64bit:

  1. Download the latest Audio driver from HP site https://support.hp.com/us-en/product/hp-probook-470-g4-notebook-pc/10477368/document/c05519670  according to your type of HP or directily for this type of HP laptop: https://ftp.hp.com/pub/softpaq/sp80001-80500/sp80320.exe.
  2. Extract it to the ProBook / EliteBook / etc and install it.
  3. Reboot after the installation.
  4. You will still get the error after login again. No worry.
  5. Go to this folder C:\Program Files\CONEXANT\SA3\HP-NB-AIO, run setup64.exe.
  6. You will be prompted to UPGRADE, go ahead.
  7. Then reboot the laptop again.
  8. After login, the error is gone. But it is not done yet, you have no sound on the laptop.
  9. Simply go to the taskbar and look for the Speaker icon, click on the Troubleshoot sound problems and the problem will be fixed.

Anyway, when you are facing this problem you need to check the office website for the Audio driver from HP because time to time they update a new audio driver and then you have to download the latest one.

 

Hope this helps, it resolved my problem!

 

Good luck to all you !

Same here. After update the latest driver from Hp support assistant, there is no sound anymore. Actually after reboot the speaker can sound for several minutes. After that I have to reboot to make it sound some other minutes. **bleep**ing ridiculous.

Fabulous review, it helped me a lot with the same problem. I am also on a ProBook 470 G4 with WIndows 10, 64-bit.

 

In my case the only thing that I had to do additionally was to run the HP "Operating System Diagnostics", where a fix was performed. Afterwards your fix worked perfectly. Thanks for that.

I have been through the solutions as I have this very problem. 

I am getting errors with the update or driver software not being able to be accessed.  Therefore I cannot get rid of the flag that appears 

 

I have a HP Envy 360 laptop

 

Any assistance would be appreciated

 

Thank you 

 

Regards

Simon
