Hmm...I don't recall a frontend option like that, but I'll check that this
evening when I get home.  And yes, I did enable the spdif output, using
gnome-alsamixer.  The thing is, I am failing to get output from either the
headphone line-out or the spdif-out on the soundblaster (except when I use
mplayer)...
