Re: Lenovo Y400 No Sound

hi orimac11,


Welcome to the Lenovo Forums.


Is the sound working fine before you installed the Windows Update?


Can you try to:

1. Navigate to the Control Panel > Hardware and Sound > Sound and under the Sound Properties, check if the built-in speaker is set as the default playback device.

2. Open Device Manager (press Winkey+R > type devmgmt.msc) and under Sound,video, and game controllers, right click and uninstall the Audio Device and reboot.

3. If you're still not getting any sound from the speakers and the volume bar fluctuates, try to plug-in a headset or an earphone and observe


If the sound is working by using a headset/earphone, it's possible that the windows update corrupted the driver or there's a short on the speakers. You can try uninstall the sound driver completely and re-install it back or you can perform a system restore to undo any changes that might have caused the issue. If this fails, you may need to contact lenovo for service.



Let me know your findings,
