Windows 10: No sound on Thinkpad T520

I have no sound on ThinkPad T520 except at headphone jack, Win 10 version 1607 OS build14393.351, I have a ThinkPad T420 with Win 10 version 1607, OS build 14393.447 the T420 has sound from speakers and headphone jack. I have the latest Conexant driver in the T520, I have done all the "problem solvers" i can find online and nothing works. Is this a software problem or equipment problem.

Sound is not working on Lenovo Thinkpad T400 after Windows 10 upgrade????

I had a similar issue after upgrading a T520 with Mini dock series to Windows 10.

Analog sound connected via 3,5 plug in the dock (!) did not work.

Re-installed the Conexant drivers version 8.32.43.0 under Windows 10. (these seem to be the newest)

Products :: laptops and netbooks :: thinkpad t series laptops :: thinkpad t520 :: downloads :: ds032124 contentdetail

This fixed the issue.

Kindly let us know if you need any further assistance with Windows, we are glad to assist you.

 

Troubleshooting Thinkpad audio - You have described a hardware problem with the T520. Download the hardware manual from Lenovo and determine if the headphone jack is part of a replaceable assembly and replace it if so. If the headphone jack is part of the system board the problem is more complicate to repair. You can go to Lenovo's site, plug in the full model number, like 5170-339, and locate the hardware manual--Lenovo's forum is the best place for help with a ThinkPad.

 

Try to manually update to the latest driver posted on Lenovo Support.
