Giving access to your mic or enabling push-to-talk can fix the mic not working issue.

Dota 2 is a game that relies on teamwork and for this reason, players get the option to communicate through text chat and audio chat via a mic. Whether it’s to form a strategy to destroy the enemy ancient. Or if it’s a plan to set up an ambush to win a team fight it is vital that the whole team is in communication with each other.

Yet many players report that their mic is not working in Dota 2 and instead is crossed out with a red slash. Yet their mic works fine (2) outside the game. Using text chat is fine as an alternative to voice chat. But when players are in the heat of battle they may not find the time to use the text chat.

5. Configuring Open Mic Settings

If you are facing issues with Open Mic then one known fix is to lower the Open Mic Threshold to 6% or below it. According to the user who reported this fix the threshold level must not go above 7% or Dota 2 will stop detecting your audio. This setting can be found under the Voice section of the settings and can be adjusted using the slider.

6. Close Background Apps with Microphone Access

Apps like Discord, Skype, etc. can sometimes take exclusive control of the mic and cause Dota 2 mic not working issues. You can check to see if this is the problem by shutting down these apps and restarting Dota 2 to see if the problem has been fixed.

If the problem has been fixed by closing these apps then you may want to switch to Push To Talk mode in these apps. This will prevent these apps from having access to your mic exclusively at all times.

7. Reinstall Microphone Drivers

If none of the above fixes worked for you then as a final effort you can try to reinstall the mic drivers either. This can be done by Device Manager or by using a 3rd party driver updater app known as Driver Easy. Reinstalling audio drivers fixes many issues Including the saved settings of previous drivers which may be causing the mic to not work in Dota 2. This is also completely reset upon new installation.
