Windows 10: why does my audio keep going to zero?

My speaker audio keeps going to off position. I move it up in volume and it immediately goes back to zero. there is always an "X" on the speaker when it goes back to zero. I upgraded from Win 8.1 which the problem existed there to windows 10 in hopes that that would help. But, alas, no help.

Audio volume keeps forcing to zero.

Tried your suggestion. Troubleshooter tells to increase volume in mixer, which I did. Volume quickly goes back to zero, as before. Troubleshooter says :unable to fix all of the issues found.

Problems found:

Low audio volume Not fixed

Audio device muted Not fixed

 

Can not record audio.

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.
