Hello guys.
Many of you have asked me how I removed the sound at the beginning of the mission. I mean the voice of this lady, as soon as the mission begins. It can easily turn off, now I will show you how.

Okey, first you must find your location of the game. E.x C/Program files/Games/VuGames and here go. Okey, once you find location, open content, next sounds and into ScriptedVO. Okey, here you have music files. You must delete all files that end on .dis. Remember, if you are not sure you can do a copy.
Here you have the files that must be removed:

Content\Sounds\ScriptedVO\AbombLoad_dis
Content\Sounds\ScriptedVO\ArmsDealLoad_dis
Content\Sounds\ScriptedVO\BarberLoad_dis
Content\Sounds\ScriptedVO\DNALoad_dis
Content\Sounds\ScriptedVO\FairfaxLoad_dis
Content\Sounds\ScriptedVO\FoodWallLoad_dis
Content\Sounds\ScriptedVO\HospitalLoad_dis
Content\Sounds\ScriptedVO\HotelLoad_dis
Content\Sounds\ScriptedVO\JewelLoad_dis
Content\Sounds\ScriptedVO\QwikLoad_dis
Content\Sounds\ScriptedVO\RedLoad_dis
Content\Sounds\ScriptedVO\TenementLoad_dis
Content\Sounds\ScriptedVO\VictoryLoad_dis

Okey, after that go again to your swat 4 location. Now go to ContentExpansion, now LocalizedContent, Int, and finally Sounds. Now you just have to find a folder ScriptedVO. Again delete files who ends on .dis:

ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\Arcade_Load_dis
ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\Backstage_Load_dis
ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\Druglab_Load_dis
ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\HalfwayHouse_Load_dis
ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\Office_Load_dis
ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\Subway_Load_dis
ContentExpansion\LocalizedContent\int\Sounds\ScriptedVO\Warehouse_Load_dis

Have fun with fast start smile
