Readiness progress 15%/100%

The values of the default console variables differ depending on the hardware/device configuration, as well as the way they work and their presence on different Source Engine builds and games and in different mods (unofficial Valve games).

Please report if you have problems because of some commands are crashing, errors, or it just does not work on your pc. Also some commands may not work on the server, because they are overridden in the server config, and when you connect to the server, your settings will be overridden.

voice_enable
Value 1
// Turn on microphone sound

voice_fadeouttime
Value 0 def.
// Affects the fade out time of your voice

Value

You can also use them
snd_mixahead
// A low value can cause jerky and wheezy sounds. It's probably undesirable to use it if you're not getting a decent frame rate, as the drop in performance causes sounds to stutter and crackle

If you want, you can use the ready-made config
This does not mean that it will be optimal for you, and suitable in all events and situations
