The same for me.

I don't have the mixer too, this seems to be an upstream bug:

Some other applets such as a system monitor will not display at all.
If you have installed ports from svn you can revert to the 1.8 version
following ports:

# cd /usr/ports/x11/mate-applets
# svn up -r 382163
# make all reinstall clean
# cd /usr/ports/x11/mate-panel
# svn up -r 374688
# make all reinstall clean
# cd /usr/ports/audio/mate-media
# svn up -r 386756
# make all reinstall clean

After that the applets work correctly and you will have the mixer too.

If you are using portsnap then move for a while /usr/ports and checkout
ports from svn.
# cd /usr
# mv ports ports.portsnap
# svn co svn://svn.freebsd.org/ports/head ports

You can also check audio/xfce4-mixer, that mixer looks reasonable.

I am very confused how the mate developing is going, either the
developers are too busy or noone cares about this project. Some time ago
I found a bug in caja:
http://forums.mate-desktop.org/viewtopic.php?f=2&t=3093
I have created a path:
https://github.com/mate-desktop/caja/pull/309
https://github.com/mate-desktop/caja/pull/307
but within year the developers are not able to either commit it or just
say something.
