FIX Sound broken/no audio output device after using Avast Driver Updater

Avast Driver Updater
1

Hi everyone. After a day trying to fix the problem, I finally bring back my audio. What I did is restore all the driver that has the “Audio”, and “Sound” in its name. In my case, these drivers are:

  • Intel Display Audio
  • Intel Smart Sound Technology Audio Controller
  • Intel Smart Sound Technology OED
  • Realtek Audio Universal Service
  • Realtek Audio Effects Component

After I restored these drivers, I restarted my laptop and the audio came back.

Hello,

first of all let me sincerely apologize for all troubles associated with usage of our product.
We really try to make the product better but there are still cases when a wrong driver is installed and then it causes such issues.
We also work on a feature which should help users to easily revert all drivers connected to a particular device (e.g. in your case it would be sound) so in future there will be no need to find them one by one in Windows but you should be able to revert them from one place directly inside our product.
What is probably more important though is that we are also trying to improve the detection and installation process to eliminate such issues at the first place and there will be a better detection in one of the future updates.

I know that all of this does not “erase” what already happened to you. I just want to tell you that we are constantly doing our best to improve our product to make sure that such situations either won’t happen at all or at least there will be a bare minimum of them.

Thank you for your feedback and have a nice day!

Hi. The same is happening to me and I don’t know how to fix it.
Avast Driver Updater installed a new version of the Realtek Audio in my computer 2 weeks ago and since that day the audio doesn’t work.
But I don’t know how to restore the old version or fix this issue, because when I click “Driver versions” it only shows this current version, installed now.
How can I fix it then?
thank you
Helena

Hi Helena, I already answered in “your” thread. Best regards, Uli

I’m having the same problem. I updated my drivers and now my sound doesn’t work. I used your support chat and that was a joke… They spent 1.5 hrs and barely did anything at all. Most of the chat was me sitting there wondering where they went, because they weren’t doing anything and weren’t letting me know what was going on.

They tried one thing to solve the problem in 1.5 hrs (uninstalled the driver and restarted) which I’d already done and it didn’t work. They sent my issue to their team who takes care of these things but I haven’t heard back and I need this fixed asap, as I work in the audio industry, so this is a big deal not to have working.

After the chat, I went into the Avast Driver Installer app and clicked on “Sound” and reverted all of them, then restarted but that still didn’t work. This makes no sense. I’ve reverted all drivers that have anything to do with sound but my sound still isn’t working…

A quick Google search shows that this is a common issue, so I’m not sure why it’s such a headache to get this resolved.

Hello,

first of all let me sincerely apologize for all troubles associated with usage of our product.
We really try to make the product better but there are still cases when a wrong driver is installed and then it causes such issues.

In order to be able to help you I would like to ask you to send the log files so we can investigate where the problem is.
We replaced our previous log collector tool with the official Avast Support Tool which is more or less the same however just to make sure here is the process:

[ol]- Open Driver Updater - Menu - Settings - Troubleshooting

  • Click “Open Support Tool” button at the top
  • Confirm the Windows User Access Control dialog to start the tool
  • After the initial check click “Next”
  • Fill in your email address so we can contact you afterwards if necessary
  • Click “Generate” button to start the process
  • When everything is finished, send me the code displayed in the final screen (see the attached picture) so we can find the right package associated with it[/ol]

Thank you for your cooperation. We will try to investigate this issue as soon as possible and get back to you.

I’m having this issue also. What little sound comes out is all tinny and muted. I tried the instructions from the moderator above, but my version of Driver Updater (I just downloaded and installed) does not have anything called an “Open Support Tool” under Troubleshooting.

I have the same problem. I’ve tried to click on button “Solve now” but it doesn’t work. So I don’t have any sound after last installation of drivers recommended by Avast :-\

this function doesn’t work, I’ve tried it :-\

None of these work for me. I have a new laptop - less than 24 hours old, and driver updater has completely corrupted my audio drivers. I can’t even see Realtek audio, nor can I install the driver from the laptop manufacturer’s website. Avast has lost me as a customer over this.

After using Avast Driver update my audio in and out is not working anymore on a Windows 11 Lenovo Thinkpad T15; also Windows reinstalation and Realtek reinstalation and Lenovo updates dont change “Audio is not available”… so a 3-year old problem still producing headache.
