This sounds like it could be a mismatch between the versions of the 
program alsactl and alsa-lib.  It seems to be looking in the wrong place 
for information.  The files that alsa looks in are by default installed 
in /usr/share/alsa.  Some distros put them in /etc/alsa or /etc.  Check 
if that is the case by looking at the timestamp on the files.  If the 
newer files from the upgrade to alsa-lib are in /usr/share/alsa, you can 
put symbolic links to those files, or copy them to the location where 
your distro expects them to be.

After you updated alsa-lib, did you run /sbin/ldconfig?  This updates 
the version of library being referenced for sharing.  Could be the problem.

This doesn't seem to be the same problem as the first problem.  What 
happens when you use aplay (aplay -v -D plughw:0,0 some.wav)?  Can you 
run amixer (note, not alsamixer) in a console or terminal and get 
output?  Is the output your changed file?  Can you use the gui sound 
administration tools to play the test sound and does it work?
