Use 5.1 and ignore the center channel.
I was wondering if anyone knew of any cards that did 4.1 analog out with bass management. Currently my XiFi card can only do 4.0 or 5.1 without the option for 4.1. Its more of a software issue and I was wondering if anyone has any experience with any cards that do this. Specifically, do any of the auzentech cards do this? I know the run 8v preouts which would be ideal for me.
