The thing is, that line is very specific, and I don't see how it could 
ever actually affect a sound device at all.  Some kind of syntax error 
that was preventing the rest of udev from working is the only idea I have.

Another thing to consider, you said in your first message that if you 
comment out the "lines" then your sound works.  That above entry should 
all be one line (so be sure your text editor isn't breaking it into 
multiple lines.  Also probably a typo, but there's also a comma missing 
after the Mode= option.
