iw3mp.exe COD4 Error

There are some issues running CoD 4 multiplayer on some onboard sound cards.
If you have a RealTek sound card, you can try the latest RealTek drivers

If you have a Sigmatel® onboard sound card you will need to install all Windows® Vista updates, and the latest Sigmatel drivers from www.dell.com. Please navigate from the dell homepage to support, your make and model computer, and look for a sound card update.

If you are running the game from a secondary partition, download the latest BIOS updates from your motherboard manufacturer in addition to following the above instructions.

If you have the RealTek soundcard and the above doesn't resolve the issue then try the following:

Go to Start then Control Panel
Double click on the Sound Tool
Click on the Recording tab
Right click anywhere in the Playback Devices box and select "Show Disabled Devices"
Enable the Stereo Mix

If all else fails try connecting something to the microphone jack on your sound card. A microphone is optimal but using a pair of headphones or even just a phono plug adapter will work. Do not plug anything that is powered into your microphone jack as it could cause damage to your system. Also, there have been reports from some customers that plugging in a USB microphone into an available USB port may have a positive affect on this issue.

Information Copied from the Activision's help site.
