Outdated or faulty audio drivers can often cause problems with mic chat functionality. To update your drivers, follow these steps:

  • 1. Type "device manager" in the search box located on your taskbar. This will open the Device Manager window.

Step 4: Disable SIP-ALG


SIP-ALG (Session Initiation Protocol Application Layer Gateway) can sometimes interfere with voice chat functionality. Here's how you can disable it:

  • 1. Access your router's administration page by typing its IP address into a web browser. The IP address is usually printed on the back of the router or can be found in the router's manual.
  • 2. Once you've accessed the administration page, find the SIP-ALG settings within the router's configuration options. The location of these settings may vary depending on the router model and manufacturer.
  • 3. Disable SIP-ALG and save the changes. This will prevent any interference from SIP-ALG and improve the performance of your voice chat.

Step 5: Restart Your Router


Lastly, a simple router restart can often resolve connectivity issues. Follow these steps:

  • 1. Disconnect your router from the power source. Locate the power cable at the back of the router and unplug it.
  • 2. Wait for approximately 30 seconds to a minute. This will give enough time for the router to fully power down.


By following these friendly troubleshooting steps, you should be able to fix mic chat issues in Call of Duty Modern Warfare 3. Remember to double-check your audio settings, update drivers, disable SIP-ALG if necessary, and restart your router. These steps should help resolve any audio issues you may be experiencing, allowing you to fully enjoy the game with clear voice chat. Happy gaming!
