These two cards are different, emu10k1  have "rear" device,  "centerlfe"
and "side" devices

but they use multi plugin instead of surroundxx use pcm.front

SB-XFi.pcm.surround40.0 cards.SB-XFi.pcm.front.0
SB-XFi.pcm.surround51.0 cards.SB-XFi.pcm.front.0
SB-XFi.pcm.surround71.0 cards.SB-XFi.pcm.front.0
