When I originally wrote up how to install MATE I did not include the packages you need to enable audio play back (my excuse is that I was aiming to install as little as possible).
Fortunately that is easily rectified!
Adding audio support using ALSA
To enable audio playback using ALSA you need to use the command below to install the additional packages required.
# apt-get install alsa-base alsa-utils gstreamer0.10-alsa \ > mate-media-gstreamer mate-media-common mate-media-gstreamer \ > gstreamer0.10-plugins-base gstreamer0.10-plugins-good Reading package lists...

To test that everything is working use the following command to play one of the test sounds installed with the ALSA package.
# aplay /usr/share/sounds/alsa/Front_Center.wav
Note – You may find that the volume is muted by default, you can adjust the volume using the volume control on the ‘Sound & Video’ menu.
