I have just bought Call of Duty 4 and a new laptop. When I try an go on singleplayer it works perfectly, but the problem comes when I go on multiplayer. I start to load it up, it starts up but then it says 'iw3mp has stopped working'. What do I do?
My Computer specs;
Sony Vaio VGN-NR21Z/S Notebook Core 2 Duo (T8100) 2.10GHz 3072MB (1x2GB + 1x1GB) 250GB 15.4 inch WXGA TFT DVDÂ±RW DL/RAM Modem WLAN Vista Home Premium (nVidia GeForce 8400M GT 128MB) - Silver
Don't know why my last message got deleted? It was perfectly reasonable and was the answer to this problem. Well if this help, and isn't deleted! You need to go to hardware and sound. After this go into sound. There will be 3 tabs within this window. Go to the recording tab. In here you should see something called stereo mix. This needs to be enable or disabled depending on what it is already set to. I hope this helps. It worked for me and my friends.
Here is the fix. Go to my computer / devices then disable your sound card. Then go in COD4, ALT+TAB, then enable your sound card again. Then go to sound settings in COD4 then click through the sound cards until it goes back to the one it was set for... I believe is milesfast 2d audio... then it should be working fine.
hey, dunno if u solved it yet, think you might hav, but if u hav no headset and mic, try this. go into control panel , then into hardware and sound, then into sound, then into the tab which says recording. in this section there is usually a thing called stereo mix. disable or enable it depending on what it is already set to. it worked for me and 5 m8s. good luck. :)
Believe it or not, I just upgraded to Windows 7, myself, and encountered that issue.
On a tip from a forum like this one, someone suggested that I plug in the headphones and a microphone. Not having a headset, I got out a microphone from my stereo equipment that had the same size mic jack as the PC. I plugged it in. My headphones were already plugged in.
Oddly enough, IT WORKED!
I then closed Modern Warfare, then pulled out the MIC, then restarted it. It didn't work!
I plugged the mic back in, and it worked, so I just have the mic plugged in all the time now.
I was totally skeptical that this would work, but I think you should try it. I think I know the type of programming error that caused it. Windows 7 may have changed one or more multimedia instructions, making the subroutine that checks the mic work differently. A patch from Activision should fix this, but it's not a serious issue. Just plug a mic into the Mic jack, and you should be back to your killing.
You wont believe this but.. plug in a mic.. ys a microphone.. I has something to do with the sound and audio settings interfering and a mic does a good job of fixing it.. look around the net for some advice so u dont have to plug a mic in all the time but it worked for me and yes I know its almost un believable
