Thanks, that fixed it.

As an aside I had to patch alsa-utils/alsactl/names.c to make it work 
with my alsa lib as I have disabled midi & seq support. The patch is 
below, the problem with it is that alsa-lib does not expose in a header 
anywhere what is enabled/disabled (alsa-lib/include/config.h appears to 
be a private header that does not get installed).
