COD4 Windows Vista Audio Drivers Fix

CoD4Boards · #1 04-26-2008, 09:51 PM

To fix the Vista Audio driver problem you have to double-click on that orange loud speaker symbol in your task bar, then click on the folder icon in the upper right edge and activate "Disable front panel jack detection". This will force the driver to load microphone support even without a mic plugged in.

Furthermore you have to make sure that (in case your using the digital output, like me) your Digital Output device is set as default. To do that, go into the HD Audio Manager (orange load speaker) again, click on Digital Output in the upper bar and on "Set Default Device" next to the volume adjuster after.

Thanks to Xero|Hawk from the Infinity Ward forums for this fix. Below is his original post and some technical information.

JMP.&DSOUND.#6 is a JMP to DSOUND.DirectSoundCaptureCreate, and its return value is directly used for the string formatting. Most likely the programmer wanted to have a formatted error message displayed (which would be DSERR_NODRIVER), or the error value in hex, or whatever, but instead he treated the return value as a string pointer and because the formatting func doesnt do a IsBadReadPtr check on it before handling it, the game crashes. I tried changing the %s to %X which fixes this crash indeed, but because the DirectSoundCaptureCreate call isnt supposed to fail, the game crashes at a different position, probably when its trying to use the interface the first time.

Code:

Code:

0057A7E2  |.  803D 4EB55E0D>|CMP BYTE PTR DS:[D5EB54E],0 <-- the IsCaptureInitialized bool, most likely
0057A7E9  |.  75 04         |JNZ SHORT iw3mp2.0057A7EF <-- but because the Create call failed, its not (see code snippet above),...
0057A7EB  |.  33F6          |XOR ESI,ESI <-- ...so make ESI zero...
0057A7ED  |.  EB 45         |JMP SHORT iw3mp2.0057A834 <-- ...and jump to our crashing code line (it uses ESI as pointer - very smart)

32 Bit Vista Here

To fix the Vista Audio driver problem you have to double-click on that orange loud speaker symbol in your task bar
Don't have one in my task bar.

then click on the folder icon in the upper right edge and activate "Disable front panel jack detection". This will force the driver to load microphone support even without a mic plugged in.
Can't find that folder, tried searching under Sound under control panel and no results.

Furthermore you have to make sure that (in case your using the digital output, like me) your Digital Output device is set as default. To do that, go into the HD Audio Manager (orange load speaker) again, click on Digital Output in the upper bar and on "Set Default Device" next to the volume adjuster after.
Don't have that.

If it is not there you should be able to run it from the start menu under programs. If not it will be on your system drive in the Programs Folder.
