[patch] little-endian dmasound silently fails

ha. that's a pun. it's not silent at all when you listen.

seriously, the dmasound driver advertises itself as little-endian capable
but doesn't provide the proper translators. so clients like openh323
switch the mode to little-endian (without any errors) and write
little-endian data and the result is a hissing noise!

i think this is all that is needed so the little-endian switch will fail
(i can't test this; i'm not at home). the proper fix will be to implement
the little-endian versions and i've started that but i'm getting mired in
the details -- this is terse code!
