Grant, could you please try the attached patch. I haven't tested all 128 
controls but it seems to work fine here. And while you're at it, could 
you please try some other "outs" as well. My FTU is in a rack and I 
can't easily access out 5-8.

That's true. I abused the term "Capture Volume" for my purely personal 
interest, since it made navigating through the controls easier in 
alsamixer and alsamixer-qt4. So, Daniel and Takashi, please feel free to 
change the names  to whatever you think is more appropriate.

Kind regards,
