Problem In Dell Vostro1440 Sound

In case it’s a recent phenomenon that you have experienced on the system, would recommend you to do a system restore and take the system to a prior date when it was working fine.

At times it might also happen due to the updates not being properly installed on the system.

To perform System Restore click on the link below:

You can refer the Dell Article 266590 on www.support.dell.com

Note- Any application recently installed on the computer would be erased. However, the files and folder would be safe.

If the above mentioned steps don’t resolve the issue, update the Audio drivers by clicking on the link below:

Enter the Service Tag, select the Operating System you are using and then download the latest Audio driver.

Also, run Windows Audio Playback Diagnose and Repair from the below MS FIX-IT

I also would recommend you to plug in the Headphone/external speakers on the computer to check functionality. If you are getting sound then it’s an issue with the speaker of the laptop.

 Please reply if you have any further questions.
