I'm trying to make a 5.1 surround mix in Vegas 4.0,  but I can never seem to control the center channel or LFE channel. 
I'm using a Soundblaster Live 5.1.  From poking around on this forum and elsewhere,  I'm thinking that I need the ASIO drivers from kxproject,  but I can't tell for sure.  
Should this solve my problem or am I missing something? 
Thanks,
Chris
