WhatsApp Web and Zoom Audio Blocked since Upgrade to 11.4.0.233. [MOVED]

[Rico]

Hello,

I recently upgraded my Windows 10 19043 laptop to KAspersky Endpoint Security for Windows 11.4.0.233 from 11.1.

Previously, everything was working fine but, since the upgrade, I cannot get WhatsApp Web or Zoom to recognise the PC Speakers. The microphone works absolutely fine in both. If I use MS Teams, both microphone and speakers work perfectly.

I’ve checked the trusted apps, and both Zoom and WhatsApp Web are listed in there, and they both have access to mic and speakers.

Any help would be greatly appreciated.

Many thanks.

Greetings Rico,

The speakers and microphone will be blocked if the application falls into a group other than trusted on Host Intrusion Prevention; please check this article:

https://support.kaspersky.com/KESWin/11.6.0/en-US/134861.htm

You can add the application to trusted using these steps:

Changing the trust group of an application (Section-How to change the trust group of an application in the Administration Console (MMC))
https://support.kaspersky.com/KESWin/11.6.0/en-US/123280.htm

You can find general information about Host Intrusion Prevention here:

Host Intrusion Prevention
https://support.kaspersky.com/KESWin/11.6.0/en-US/39265.htm

I will also recommend upgrading to the latest version of endpoint 11.6:

I hope this information helps.

Hello,

Thank you for the reply. I’ve tried upgrading, and adding both WhatsApp Web and Zoom to trusted applications (they were already). This didn’t fix the issue.

I have also tried to turn off “host intrusion detection” completely in the interface, and that hasn’t made either work.

With Zoom, if I go in to settings my microphone is working fine but the speakers aren’t. In WhatsApp Web I get an error message saying there is no microphone available when I try and make a video or voice call. This only happened in upgrading from 11.1.

I have also tried uninstalling and reinstalling both applications, and that hasn’t resolved it either.

I’m at a bit of a loss as to what to try next, short of uninstalling the client (which I don’t really want to do).

Many thanks.
