maybe this will help u
don't remove the original xlive.dll
Install LCPDFR with dsound.dll checked,
check ur installation, it's okay with double asi loader (Original Xlive.dll from game installation & Dsound.dll from LCPDFR)
and then. set the LCPDFR configuration, as you like..
then start the game
i tried this , and it worked for me..
Sorry for my bad english, i'm still learn ^^
