Hi roadrunner_7a, 

Please follow the below mentioned steps to troubleshoot the issue:

1. Run the Windows Audio Playback Diagnose and Repair from the below Microsoft FIX-IT link: http://bit.ly/JvQScV
2. Perform System Restore (only if Software Configuration Changes were made) providing the link for your reference: http://bit.ly/c6PWjX
3. Power off the computer.
4. Press and hold the FN key and then power on the computer. Release the Fn key when the diagnostics screen pops up.
5. When the LCD test you would see plain colored screen flashing, you would get a prompt with Yes and No as options.
6. Please select No, by using the letter N key and the system should beep.
7. If it makes a beep sound, then it would indicate that the internal speakers are working.

NOTE: With system restore you will not lose any data from the computer, any new programs installed in the computer has to be reinstalled on the computer. 

Hi roadrunner_7a,

Hi roadrunner_7a,

It looks like the issue is with the speakers and needs a replacement.

You can check the warranty status here.

If the computer warranty is active, I request you to private message the system service tag number. To private message, accept my friend request; click on my user name and click start conversation.

In case of expired warranty scenario, we would not be able to extend warranty entitled services. If the warranty on the computer has expired, you may contact our Expired Warranty Support  (this is for US based customers).

Hi, the first problem is that the microsoft fix it, didn't work, because it shows that the os(win 8) is incompatible yet.
It happens to me also, but it's interesting, because the sound gone while I tried to answer my friend on skype(skype showed me that unable to play the sound via speakers), and now when I try to open a video on youtube it shows me an error on every video. The sound isn't going trough the headspeakers too.

Hello. Please tell us what is your model of Dell laptop. In your "tags" field you put both Inspiron N5010 and Studio 1647. Is it one of those models.

You mentioned Win 8. Is that your operating system? Neither the N5010 or the Studio 1647 was shipped with Win8. Are you having this problem right after installing a new operating system?

You mentioned no sound on Skype and youtube. Did you get any sound when simply playing audio files?

Sorry mine is 5423. And it has been solved after reinstalling the sound driver and rebooting the computer. But issues with missing drivers aren't for first time. Before this I had some issues like this with the synaptics mouse.

Thanks for the update. Glad it's fixed.

Hello,

I have a similar problem after upgrading to window 8. Kindly provide solution for this

Hello Manpreet Singh. You have not yet shared the name of your Dell laptop with us. At the moment all I can say is to install or re-install the audio driver for your model from the Dell page.
