Call Of Duty 4 (COD 4) runs well on the single player game option, however, there are problems when you switch to the multiplayer mode. First, ascertain your computer model and look for a sound card update. If video games are installed on a secondary partition, download the latest BIOS updates for your system's motherboard. Some soundcards need additional instructions and setting the sound tool is done by enabling Stereo Mix. In addition, a USB microphone plugged in the system's USB port may solve the issue. It is observed that while connecting a microphone jack to the sound card, a pair of headphones or RCA connectors will eliminate the problem. Plugging into a microphone jack can result in breakdown of components in your system.
I have installed COD4 on my Windows machine. All other games work correctly, but when I try to run COD4 it crashes.
This is a very common problem caused by the system's audio device.
COD4 should now run normally
- Go to Start > Control Panel
- Double click on the Sound Tool
- Click on the Recording tab
- Right click and select "View Disabled Devices"
- Enable the Stereo Mix
