Thanks, I have done as suggested and still the same.
I then used YAST to uninstall everything to do with pulse audio, and Evolution is still not producing sound. Banshee still works and if I double click a sound clip it opens and plays in Totem.
I don't have any volume control icon on the bottom panel. I don't know if there should be one indicating a default sound driver?
I had two error reports on boot up before deleting all of pulse audio but I can't copy the screen shot into this note.
Having deleted all of PulseAudio they no longer are appearing. I don't know if these messages are helpful....

The 1st is a PackageKit Error reporting "an internal system error has occurred" --- repo-oss:Valid metadata not found at specified URL(s)

The second error window says:
"The Avahi Zeroconf service is not running. Please make sure that Avahi is installed and activated before starting the PulseAudio Device Chooser."
