well, u can adjust this feature later as well , though you are on Analogue as if you use PC.
and if you have digital cable (that comes with Audigy 2 ZS and above versions) and u have attached it to the DVD and Audigy, then you can take advantage of digital audio as well, checge the setting afterwards. not to worry this isnt windows/software installation that once u installed in some partition, you cannot change settings after wards.
