Windows 7: No sound Dell Inspiron - culprit Windows updates? ERUNT? anti-virus?

No sound Dell Inspiron - culprit Windows updates? ERUNT? anti-virus?

Several weeks ago my laptop stopped producing sound. I have investigated multiple options and am wondering if there have been any recent known bugs in lost sound, due to upgrades or something else that caused problems for others. I have tried the following:

- double-checking all the keyboard "F" function keys
- using Dell's trouble-shooting tools and instructions, which tell me the sound components are in good order
- updating drivers/removing and re-installing drivers
- using Windows' and control panel's trouble-shooting tools
- altering the sound "theme" offered by Windows
- adjusted the volume settings on my laptop

My laptop has IDT High Definition Audio CODEC as the default sound device. I don't use plug-in speakers or headphones.

I haven't dropped, jarred or otherwise damaged the laptop.

However, over the past several weeks I have:

- installed ERUNT as an emergency recovery utility (I receive error messages when I log on, so I think this utility is not working properly, but I haven't had a chance to troubleshoot it or remove it)
- installed suggested Windows updates
- installed MS Office updates
- regularly run Spybot and Spyhunter in addition to Malwarebytes

I noticed that my browser is slow and often locking up. I have to go into the Task Manager to get things moving again. I wonder if this is caused by script problems - Java, Shockwave? Could one of these be affecting my sound?

Thanks in advance for any assistance. It's driving me crazy not to have any sound.

Try System Restore, choose a restore point before the issue began.

Thank you for the fast response!

I've never done a system restore. I understand the concept but am worried about what I will lose. How do I anticipate that, or is there a way to selectively restore?

Hi sweetpatootie,

Welcome to Seven forums.

System restore doesn't affect your data files. It would remove any installed updates or programs on the system which were installed after the restore point.

So you can go ahead with the same. Also, let us know the model number for the system you have so we can advise you on updating the audio drivers.

Kindly update your system specs here by following this.

You can try updating the audio driver for your system by following this video below:

Updating Dell Drivers

Keep us posted with the results so we can advise you further.

Sorry, I didn't realize you wouldn't think to click on the blue "Restore" hyperlink. Doing so, will take you to the System Restore tutorial. The steps are explained there.

Afterwards, we can work on scanning for and removing Viruses, Malware, and Spyware from your system.

Then troubleshoot the sound issue.
