The sound of silence !

Hi Beto1331, 

Did you make any recent hardware or software changes to computer?

You may check the connections of speakers if they are loose or not seated properly. You may also run the Windows Audio Playback Diagnosis and Repair from the below MS FIX-IT: http://bit.ly/10sF5Vm 

Another step you may try is to uninstall and re-install the audio drivers on your computer and see if it makes any difference. You can follow the steps below to uninstall and re install the audio drivers:  

• Click on “Start” and right click on “Computer”.
• Click on “Manage”.
• Click on “Device Manager”.
• Under “Sound Video and Game controllers”, you will find the audio driver listed.
• Right click on it and click on “uninstall”. (Check and make a note of the driver installed on your system and re-install the driver from the below steps accordingly).
• Check the box to delete the software.
• Restart your system and click on the below link: http://dell.to/14LfU0G
• Click on “Download File”.
• Select “For Single File Download via Browser”.
• Click on “Download Now”.
• Save the driver on your desktop.
• Once the driver is saved on desktop, right click on it and select “Run as administrator”.
• Install the audio driver by following the on screen instructions.
• Check if the issue is resolved. 

Please share the findings.
