The only file which is relevant in this package is the sound saving/restoring script. The other two are about sound modules and are unrelated (if not obsolete). So I suggest to add the starting script to the aumix package and doc files to sndconfig (if needed).
Probably a good idea, although we'll need to move the script to a different package (most likely) when the alsa stuff comes in...
fixed in aumix-1.22.1-2.
