"Wave XXX Volume" controls should be zero for multi-channel outputs
indeed, because these are volumes of signals duplicated from the front
channel to surround/center/lfe channels.
locking could be optional, though.

hmm, i'm not sure about this.  surround51 was designed for outputs
from three analog jacks.

what do you get from digital out with surround51?
does the card send non-encoded raw 6-channel PCM over spdif?

on Audigy, the signal routing and control elements are fairly
different from SB Live.  so, you cannot copy it simply...
