actually, i fixed it without any patch
just, one more question, can I play cod4 online with the pirated key(that comes with keygen) ?? cos, i tried it, it still says,
vTo 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.
