Windows 10: my computer keeps muting itself

This problem appeared last week. My computer permanently keeps muting itself. I am trying to increase volume, it battles with me to get itself muted. I cannot unmute. I tried every way uninstall- install drivers, windows 10 recovery, cleaning boots, deactivate even volume buttons. My laptop is lenovo yogo 300. Is there any way to fix it?

Mute-Mute-Mute

Guess I am joining the party. Have tried everything. Its a one shot deal with the microphone. I can do one command to Cortana and I get muted. Skype, I last a few seconds. My two computers are the same, a new Lenovo laptop, and my Asus Kabby Lake gamer. No malware or viruses, drivers are all up to date. Tried every suggestion I have found across Internet. Nothing has worked for me. Microsoft, you folks need to fix this bug, I'd call you and leave a message but I keep getting muted.

 

Constant Muting Internal Microphone

Hi Terri,

If the internal microphone of your device is muting on its own, it can be due to an incompatible driver, broken system components or a software conflict has occurred. To isolate your concern, we’d like to confirm if you’ve made some
changes and updates on your computer prior to the issue.

Additionally, we suggest that you run the troubleshooter to fix any sound issues. Please check this

Windows 10 Volume Mixer fails to keep System Sounds muted over Remote Desktop Connection

The problem:

after having muted the System Sounds on the remote desktop machine, it shall unmute itself after several seconds. This pattern is persistent.

The physical setting:

I use my laptop at work, and use Remote Desktop Connection to access my desktop machine left in my apartment.

The software setting:

I have enabled Remote audio through the Remote Desktop Connection, and chose Remote audio playback --> Play on this computer. Thus, I get audio streaming on my laptop at work.

My attempt:

I have tried to find a way to mute System Volumes through a shortcut, and the following pages appears to be helpful:

1. HowToGeek suggested to create a shortcut with the following executable command:
   
   “C:\Path\To\nircmd.exe” mutesysvolume 2
   
2. The same source also points me to the shortcut for opening the Volume Mixer. %SystemRoot%\System32\SndVol.exe. Yet, I failed to find a stable way to mute System Sounds through AutoHotKey.
   

The problem for the suggested approach is that, on Windows 10, nircmd.exe no longer take the option "mutesysvolume 2" as designed. Instead of toggling the System Volumes, it is toggling the Device Volume. This is different from what the specs have suggested: NirCmd - Windows command line tool
