how do I tell the computer to stay mute no matter what

Solution 1:

You can turn off Windows's Audio Service at any time, which will disable all sound devices, by typing this in the command prompt:

net stop "audiosrv"

Start it back with:

net start "audiosrv"

Most applications will deal somewhat gracefully when the service stops (read: not crash), but it's not a mute in the sense that the software is unable to send audio signal to Windows anymore. For example, Winamp and iTunes just stop playing and hold.

Also, when you start an application or a game while the service is off, it's unlikely that it will suddenly start working after turning it back on - you may need to restart the software. So your mileage may vary, depending on your intended usage.

If it works for you, you can easily assign to a hotkey (using your keyboard's software pointing to a batch file, or a third-party such as AutoHotKey).

Solution 2:

AFAIK, sound volume as well as mute are functions exposed by the base Windows API to all applications. This simple application seems to bear that out. I do not know of any way to prevent software from altering the current sound settings if the Windows API exposes them.

For the most part, I believe the idea was that if you really didn't want sound you'd just turn off or unplug the speakers. On a laptop, you could go into Sound Options (or Device Manager) and disable the audio device completely. Very few applications are going to try to enable a disabled device.

Solution 3:

I was thinking this should be possible like we can set a settings that tells the computer to heys stay mute no matter What

Just unplug your speakers.

Raymond Chen explains why what you want is impossible, at a software level.

You might want to make some software that keeps the computer mute no matter what. But then somebody else might make some software to unmute the computer, no matter what.

As Bacon Bits said, you could always disable the sound device. But another application could re-enable the sound device. You could uninstall the sound device drivers, but another application could just reinstall them.

You could uninstall the sound device drivers and flush the Windows driver cache, but another application could take the device ID of all unknown devices on your system and then send them to a web service to identify if they're sound devices and automatically reinstall the right drivers.

Why not schedule a task to uninstall the sound device drivers and flush the Windows driver cache? Make it run every 10 minutes. What is the other application going to do now? Scan device IDs every 9 minutes.

This is like saying, "Sometimes I'm in a hurry, and I want to make sure I am the next person to get served at the deli counter. To do this, I find whoever has the lowest number, knock them unconscious, and steal their ticket. But sometimes somebody else comes in who's also in a hurry. That person knocks me unconscious and steals my ticket. My plan is to set my watch alarm to wake me up periodically, and each time it wakes me up, I find the person with the lowest number, knock them unconscious, and steal their ticket. Is there a better way?"

Solution 4:

Turn down and mute the WAVE volume and turn down and mute the MASTER volume.

What exactly is the problem? Is there some software that suddenly makes noise? Turn the volume down in that software or get rid of it. If it keeps ignoring your volume setting and insisting on making noise, then it is poorly written junkware and you don’t want it; if it is decent, goodware, then it will let you decide the volume/mute setting and respect it. Also, try contacting the developer and giving them a piece of your mind; maybe they’ll fix it.

Solution 5:

Find a old pair of headphones you don't use anymore, and cut the cord at the plug and keep the plug with you. Anytime you want things muted on a hardware level, just plug the plug into the headphone jack. Since most headphone jacks use pressure switches to check if there's a plug in the jack, the plug will make the computer redirect the sound to headphones that don't exist.

Alternatively, you could try using a toothpick or a coffee stirrer, but if it breaks off you could have trouble removing it.
