Before you get confused by reading this guide and seeing all of the commands and scripts used to mute players in CS:GO, read

If you do know how to input binds using console in-game or how to create a script cfg file, which would be placed in the CS:GO directory, then you do not need to read it and can skip to the next part of this guide.

This is probably the easiest and shortest way to mute your teammates. However, it does not give them any information that you've done so. So if a teammate calls something out that is useful (ha yeah right) and you miss it, which ends up making you lose the round, you might find yourself wondering why your teammate is mad at you for the rest of the match..

bindToggle 'h' 'voice_enable'

Explanation:
What this does is creates a toggle between the values of 0 and 1 for the command voice_enable. When you click on it once, assuming you have it set to voice_enable 1 by default, it will switch the value to 0. When you click on h again, it will toggle the value back to 1 and you are then able to hear your teammates again, sadly.

The following piece of code is when you would want to mute your teammates completely.
It also contains a little team chat message for them to know they have been muted. The chat message may serve as a reminder to you to unmute your teammates when you're done clutching.

bind "h" "mute"
alias mute "muteOn"
alias "muteOn" "voice_enable 0; alias mute muteOff; say_team MUTED"
alias "muteOff" "voice_enable 1; alias mute muteOn; say_team UNMUTED"


Explanation:
What this does is binds any key, in this case it's the letter h, to the command we made called 'mute'. We then renamed mute to be called muteOn. When we call muteOn, it sets voice_enable to 0, muting everyone's mics and putting in team chat that you muted everyone. It then reassigns the command which we renamed to muteOn to be muteOff. That way when we call the command again it executes the part of the code where we re-enable voice_enable, setting it back to the default value of 1 and assigning it back to the name muteOn. It then tells your team you have unmuted them, sadly.

The following piece of code increments the level of your team's mics. You would want to use this if your teammates are unusually loud in a certain match you're playing or if you're in a server and don't really feel like having your ears bleed but would still like to hear what is going on.

bind h "incrementvar voice_scale 0 1 0.2"

Explanation:
What this code does is increments the variable voice_scale from the minimum value (the first number in this case 0) to the maximum value (the second number in this case 1). The 0.2 is what you are incrementing by, which is called delta. This means each time you press 'h' the variable voice_scale will go up by 0.2 until it gets to 1. Once it reaches 1, it will reset back to 0. So it goes from 0 to 0.2 to 0.4 to 0.6 to 0.8 to 1 and then finally back to 0.

Here is just some situational incrementvar voice_scale binds you may find useful depending on what you're looking for.

So let's say for example I have sensitive ears and hate the sound of nerds. I would set my bind to be something like this.

bind h "incrementvar voice_scale 0.1 0.5 0.05"

What this does is makes my minimum value 0.1 as I do not want to mute my teammates at all during the match. It sets the highest value to 0.5, which is half of the maximum value possible for the variable voice_scale. Then I set my delta, the increment value, to 0.05. So this makes the values possible to be 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5.

These might seem like a lot of values to toggle through so I might change the bind to be something like this to shorten the time I have to spend toggling to get from the lowest value to the highest.

bind h "incrementvar voice_scale 0.1 0.5 0.1"

This sets the values I can toggle through to now be 0.1, 0.2, 0.3, 0.4, 0.5.

NOTICE:
If you've noticed I made sure to use delta values that are divisible by the range between my minimum and maximum values. This means if I were to have a minimum of 1 and a maximum of 10, I would use a delta value of 1, 2, or 5. If I used 3, my toggle values would be 1, 3, 6, 9 and would skip 10 and go back to 1. If I used 4, my toggle values would be 1, 4, 8 and then back to 1. You can use that if you'd like to increment faster, however be careful. You might not be reaching all the values that you would want to be. For example if I had minimum value of 0.1 and maximum of 1 and my delta was 0.5, I would just be toggling between 0.1 and 0.6, as my delta value would make me skip 1 (0.5 + 0.6 = 1.1).

So let's say I want to toggle between low, medium and high, I would have the following bind.

bind h "incrementvar voice_scale 0.1 1 0.45"

This would then make my increment values 0.1, 0.55, and 1.

Debugging:
ALL INCREMENTS ASSUME THAT YOU ARE STARTING AT THE VOICE_SCALE OF THE MINIMUM VALUE SET IN THE SPECIFIED INCREMEMNTVAR. If you don't understand the meaning of this sentence or why it is relevant then just ignore it. It's not even important. It's just for debugging reasons.

The following piece of code is when you fake mute your team. Your teammates would find no point in yelling callouts to you when they know they are muted. However, if you missed an obvious footstep, there's a chance your teammate might rage and say in mic that you are deaf and can't hear the guy behind you. You're taking a risk by doing this, but you never know if it could be useful.

bind "h" "fakeMute"
alias fakeMute "fakeMuteOn"
alias "fakeMuteOn" "alias mute muteOff; say_team MUTED"
alias "fakeMuteOff" "alias mute muteOn; say_team UNMUTED"

All this code does is toggles between saying the message MUTED and UNMUTED in team chat.

If you find yourself getting distracted by the other team's chat during a match, there's a way to mute all of the other team without having to go to each player's name on the scoreboard and clicking on "Block Communication".
cl_mute_enemy_team 1
What the command does is mutes the enemy team.

If you want to unmute you would type in console
cl_mute_enemy_team 0
This unmutes the enemy team, enabling you to see their in-game chat again.

Of course you can make a bind that toggles these values.
bindToggle h "cl_mute_enemy_team"
This toggles between muting and unmuted the other team's public chat by pushing the same button, in this case the letter 'h'.

The following YouTube video shows you what it's like to toggle different voice_scale values and how muting your teammates along with a team chat message letting them know you have muted them.

If there is a specific player who is louder than the rest of your teammates, you can lower their volume individually. In console type:

voice_player_volume

A list of players in your lobby should print out in console like this:
Player# Player Name Volume
------- ----------- ------
------- ----------- ------

To lower one player's volume, type in console:
voice_player_volume player# volume

So for example:
Player# Player Name Volume
1 BigMak 1
2 Probmatic 1

If you want to lower BigMak you would type in console:
voice_player_volume 1 0.5

This will lower the player volume by half.
