Windows 10: Audio muting itself

Does anyone know what might cause the audio to mute itself . Ive seen the behavior on a couple of different machines now, mainly HP Probook laptops. It seems to happen most often during Zoom meetings while talking the microphone and speakers randomly mute. Ive tried the following with no luck: Audio drivers are up to date (tried rolling back but no change) Exclusive mode is disabled for both mic and speakers Hardware acceleration is disabled Audio enhancement disabled Power management is set to continue running when on battery Communications activity set to do nothing Adjusted the multimedia power plan settings to optimize All background apps disabled Install all latest windows updates (inlcuding v1909)

Its not only the Zoom sounds that are muted but the entire machine with the mute light indicator on the keyboard

Volume goes to zero and mute.

Hi William,

If the volume of your computer automatically mutes, it could be that the audio drivers are corrupted or damaged, or that there are software conflicts occurring within the system. As a first troubleshooting step, we suggest that you run the audio troubleshooter
and lets Windows find and automatically resolve problems with your audio. Here's how to run the audio troubleshooter:

• Select the Start button, then type troubleshoot, and select
  Troubleshoot from the list of results. From there, select
  Playing Audio > Run the troubleshooter.

If the troubleshooter does not help resolve the problem with your volume settings, we suggest that you check Device Manager and update your sound card drivers. Updating would replace any corrupted or damaged components of the audio driver. Here's how to
update your audio drivers through Device Manager:

• Open the Start button, then type device manager, and select
  Device Manager from the search results.
• Under Sound, video and game controllers, right-click your sound card driver, then select
  Update Driver.
• Select Search automatically search for updated driver software.

If Windows doesn't find a new driver, you may look for one on the device manufacturer's website and follow their instructions on how to install their driver.

If the above steps doesn't resolve the problem, feel free to post back to us.

Volume Mixer not showing muted app

The application was muted on Windows 10 with November update. Now I am using Anniversary update, on build 14393.10

The initial step did not help make Banished show up in the Volume Mixer, nor did the article.
