Audio Missing on Yoga 2 Pro

My Lenovo Yoga 2 Pro no longer has audio and it says that hardware changes have been detected but when I try to get a new driver/update the driver, I am unable to get the audio to work again. What should I do?

Re: Audio Missing on Yoga 2 Pro

Hello Papageorgio9

Thanks for using the Lenovo forums.

Have a read of the following, see if this is able to help at all:

Method 1:

You may run the fix it provided in the below mentioned article and check if it assists you resolve the issue -


Method 2:

If the issue persists I would suggest you to try uninstalling and reinstalling the sound drivers. Follow the steps to checking the sound drivers in device manager:

a.     Click Start, and then click Control Panel.

b.    Click System and Maintenance, click System, and then clickDevice Manager
Note If Control Panel is in Classic View, double-click System, and then click Device Manager.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed.

c.     In Device Manager, expand Sound, video and game controllers. Now you may right-click the listed sound driver. Here you will get all the option to update or Install/uninstall drivers. Click on Uninstall.

d.     Restart the computer. This will let the computer automatically detect the device drivers on restart of the computer.


Refer to the below mentioned link for assistance on updating the drivers –
