Frequently Asked Questions

Why is there no sound on my ThinkPad X201 Tablet after upgrading to Windows 10?

Upgrading to Windows 10 can sometimes replace proprietary hardware drivers with basic generic ones. Your ThinkPad requires the specific Conexant 20585 SmartAudio HD driver to properly communicate with its internal sound card.

Can I use a generic Windows 10 audio driver instead?

While a generic High Definition Audio driver from Microsoft might produce basic sound output, it usually lacks support for model-specific features like advanced equalizer settings, noise cancellation, or proper headphone jack detection. Installing the official Conexant driver is highly recommended.

How do I check if my Windows 10 system is 32-bit or 64-bit?

Right-click the Start button and select 'System'. Look under the 'Device specifications' section for the 'System type' field. It will display whether you are running a 64-bit or 32-bit operating system, which will help you select the correct driver file.
