Install Conexant SmartAudio HD driver for Windows 10 x64, or download DriverPack Solution software for automatic driver installation and update. Jul 14, 2016 Conexant HD Audio Driver for Windows 10. Ship Loading Software. CX20751 SmartAudio HD Driver 8.66.4.0 for Windows 10 64. The Conexant HD Audio driver.

I bit the bullet and tried the Windows 10 upgrade (from Windows 7) on my older laptop. Everything seems to work except the headphone jack. I've tried the latest version of the Conexant driver I could find (4.98.4.60 8/24/2009) and the Windows default HD audo driver (10.0.10586.0 10/29/15). The Windows driver at least shows 'Headphones' in the playback list but with both drivers Windows fails to detect when the headphone plug is inserted into the jack - status is always 'Not plugged in'.

Anyone have any luck finding a driver for the Conexant card that works with Windows 10? The Windows troubleshooting tool is useless for this - actually causes the sound to stop working altogether while proclaiming that it has fixed my problem. Hi @, Thank you for posting at HP Forums! I have read your post and wanted to help I understand that after upgrading to Windows 10, the system cannot recognize headphones plugged in.

Have you tried to uninstall all the audio drivers in Device Manager, and click on the Action on the top of the Windows, and select Scan for hardware change to let the system install the drivers? Let me know if it works for you. By the way, I doubt if HP has the Windows 10 drivers for your laptop.
