Hi, Welcome to Microsoft answers forum. You can check for the sound drivers,whether they are installed correctly. if not uninstall them and install again. I suggest you to verify that the default sound device is set correctly Click Start,type Sound in the Start Search box. Click Sound in the search results at the top of the Start menu. Click the Playback tab. Notice the check mark next to the default device. For most users,the default device is Speakers. Make sure that your audio settings are configured as expected. Follow these steps: On the Playback tab, select the playback device, click Properties, click the Advanced tab, and make sure that the Default Format is set to the value that you expect. When you finish, close this window to return to the previous window. On the Playback tab, select the playback device, click Configure, and then make sure the configurations are set correctly. If the sound settings are set correctly, you are using speakers as the sound device, and your speakers are already set as the default device, go to method 5 now. Select the sound device that you want as the default sound device, and then click Set Default. Click OK to save your settings and to close the Sound dialog box. Determine whether you can now hear sound. If you can hear sound, the issue is resolved.

Followed Azam K's instructions. (my sound was not working at the time) When i got to the Advanced Tab, it gives you format options. Mine was on 24 bit, hit test and it did not work. I set it to 16 bit 192000 and hit test and it worked. Has worked ever since :)

Alright the fix is simple, uninstall your audio driver and reboot. Windows still has the catalog which means a malware must have created a fake one. Tested with VIA HD audio codec.

Nikhil Daund you posted to me? I can't see your post here, I thought it was a reply to my post so I deleted the email. Anyway the fact that the sound device works perfectly with the generic Microsoft driver indicates that the whole problem is a driver issue. I tried to update my Conexant SmartAudio HD drivers from the Device Manager and it said that I had the newest ones but in the Lenovo's site I found a slightly newer one than the one I had (8.64.52 instead of 8.64.49), I updated and I hope that the problem is solved - no it isn't (no sound again)!

if not uninstall them and install again.

I suggest you to verify that the default sound device is set correctly

Click Start,type Sound in the Start Search box.
Click Sound in the search results at the top of the Start menu.
Click the Playback tab. Notice the check mark next to the default device. For most users,the default device is Speakers.

Make sure that your audio settings are configured as expected. Follow these steps:

When you finish, close this window to return to the previous window.

If the sound settings are set correctly, you are using speakers as the sound device, and your speakers are already set as the default device, go to method 5 now.
Select the sound device that you want as the default sound device, and then click Set Default.
Click OK to save your settings and to close the Sound dialog box.

Determine whether you can now hear sound. If you can hear sound, the issue is resolved. If you cannot hear sound, try method 5.
