I have a Dell Inspiron E1505 Laptop. One day out of nowhere, my speakers stopped working. If I plug in my headphones, ii works fine. In device manager, it says device is working properly. I even ordered a new set of speakers from Dell and it still wont work. I searched everywhere. PLEASE HELP! Im over this!

Hi there!

I am glad that you are using Bleeping Computer as your help today!

Do you currently have an audio type named "Sigmatel"?

After you tell me this, we can diagnose the issue!

Hello again!

Thank you for your patience as we solve this issue.

If you have any questions about how to do any of this, please ask!

Assuming you have Windows Vista:
  • Please right click the volume icon in your system tray and click Playback Devices.
  • Please right click on the item that says Speaker/Headphones and click Set as Default Device.
  • Restart your computer! Your audio should work.
Please tell me if the above process did not work to solve your issue!

Please right click on My Computer and select Manage.

In the snap-in on your left, you will see "Device Manager."

Please click Device Manager. You will see a row of [+]Expand signs, please click the Expand sign for "Sound, video and game controllers" then please right click "SigmaTel High Defnition Audio CODEC" and click on Disable. Please restart your Machine afterwards! When you restart, it should make the Speakers/Headphones default. The CODEC is the underlying problem here.

Note: My confusing post was the error report and the workaround information for your issue.

Thanks for the help jay!! I did what you said and restarted. Now the volume icon has a red x on it and says ," No audio output device is installed." My speakers are not working and the headphones no longer work either. My computer now beeps. I havent heard any sounds from it in a long time, so I know we're on the right track. What do I do next?

The following step is safe, my friend. Let us do the following...

Go back in to device manager and uninstall both Audio Devices listed (HDMI and CODEC). After you uninstall the both of them, please click 'Action' at the top of the screen and click "Scan for hardware changes." Allow the wizard to complete its setup, and make sure the audio devices reinstall!

Edit: If you need any help, please ask!

Hi. I did everything you said. The red x is gone, but still I am not getting sound from speakers or headphones. When I click on the volume icon and choose play back devices, it lists: "Speakers/Headphones", and also "Digital Output Device (SPDIF Out)." Both say, " working." The speakers/ headphones are set as default.

One more time, please uninstall the audio device again and instead of scanning for hardware changes, restart your computer and allow the wizard to run. Now I know we are making progress! :thumbsup:

I had this same problem before, and I was able to solve the problem, so I know we can do this!
