Sounds are not made into debs. You must do a make sounds after to get them. I am not as familiar with the debian package system as I probably should be so I do not know if it is ok to do a ./bootstrap.sh before starting the dpkg-buildpackage or not. If it is not done you are not able to "make sounds" if it is done you have modified the source slightly and that can cause some potential issues relating to making proper packages.

The wiki does not appear to include anything on how to make sounds, and until last night the instructions would not have even made binary packages due to the missing -b arg noted above.
