PulseAudio is the standard sound server in Ubuntu Hardy Heron 8.04. A sound server is a background process that accepts sound input from one or more sources (like your applications) and redirecting it to one or more sinks (like your sound card). Unfortunately it doesn't quite work with Flash 9 support in Firefox.
There is an easy fix:
In a terminal type:
sudo apt-get install libflashsupport
Now when you have audio and video playing, Flash will have sound and vice-versa.
To get the most out of PulseAudio, you may want to download and install the device chooser.
In a terminal type:
sudo apt-get install padevchooser
sudo apt-get install pavucontrol
