Let me take that back. Building the package like this results in executables that complain about a busy device even when there is nothing contending for that device. So the current natty source does not help in creating a working alsamixer executable.
It still is mysterious to me why the natty binary package does not contain an alsamixer executable: even though it would not work, the normal build process should have produced and included one.
For now I stay with using the previous alsa-tools-gui package from Debian sid.
