lost audio output device

Recommended Posts

I just installed 3.6.1 and suddenly I have lost audio. It states "no audio output device installed". Could 3.6.1 have caused this? I've tried recommended reinstalls but no luck. Can I temporarily disable Malwarebytes to fix this problem?

Greetings,

While rare, it is certainly possible that there is some kind of I/O conflict with one of Malwarebytes drivers and your audio device causing this.  What happens if you uninstall Malwarebytes, does the audio issue go away?  I just want to verify for certain that it is being caused by Malwarebytes first before proceeding because I don't want to alter your system configuration without knowing for certain that it is necessary.

thanks for your reply . How do I uninstall malwarebytes temporarily to test this? I had some difficulty reinstalling malwarebytes when I had some problems a few years ago. Is there a quick disable to malwarebytes so I can repair my driver and then reactivate? thanks.

Just open Programs and Features and locate Malwarebytes and uninstall it.  No special procedure is required to remove it.  When you're ready to reinstall it you can download and install it from here.

You're very welcome :)

Also, if you have Malwarebytes Premium it should save your license key so that you won't have to activate it again once you reinstall it.  You can also create an account here if you haven't already (just click where it says Sign up down at the bottom of the sign in area and enter the requested information) and it will allow you to see and manage your subscriptions/licenses that you've purchased from Malwarebytes.

My guess is that this is nothing to do with Malwarebytes but is the same problem which millions of users are having with a failed Windows 10 update, now withdrawn by Microsoft.

You may be correct.  I recall hearing about audio drivers getting messed up with the last update to Windows 10 as well so it's certainly possible.

Further to AP2012's comment, see Woody Leonard's 15-Oct-2018 ComputerWorld article at https://www.computerworld.com/article/3313322/microsoft-windows/a-second-bad-driver-this-one-for-audio-gets-pushed-out-by-windows-update-protect-yourself.  According to that article a bad Intel Smart Sound Technology driver (version 09.21.00.3755) was delivered during the October 2018 Patch Tuesday of 09-Oct-2018 that turned off the Intel Smart Audio sound on some Win 10 machines, and Microsoft released bug patch KB4468550 to to the Windows Update channel on Saturday (13-Oct-2018) which uninstalls the bad driver.
