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

[LudekMatyska]

Hi,

I installed Windows 8 Pro on my HP 450 G3 and upgraded to Windows 10 (I had to upgrade because there was no display driver allowing diming of screen). Now there is SmartAudio error message after startup "A conexant audio device could not be found. The application will now exit."

CxUtilSvc is running and set to automatic startup type.

I already tried to uninstall drivers (tried to uninstall in both normal mode and safe mode) and tried to install drivers from driver CD and HP website.

Any ideas?

I have a few new ProBook 440 G3, just upgraded from Win 7 Pro 64bit to Windows 10 Pro 64bit that had the same problem. What I did is.

1. Download the latest Audio driver from HP site (http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7834513&swItemId=ob_158042_1&swEnvOid=419... a SP73979.exe file.

2. Extract it to the ProBook and install it.

3. Reboot after the installation.

4. You will still get the error after login again. No worry.

5. Goto 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 goto the taskbar and look for the Speaker icon, click on the Troubleshoot sound problems and the problem will be fixed.

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

Thank you for your post.  Your fix resolved my issue with an HP G450.  We just purchased this machine and ran the upgrade to Win10 when this error started.
