Thanks for looking at this but I have managed to resolve the problem.

The story

When I reported the problem I had updated the Realtek High Definition Audio drivers for Vista 32bit (Ver 6.0.1.5334) direct from the Realtek site so I assumed my drivers were up to date.

What I have done ...

If there is a default MIDI driver in Vista why does Earmaster not pick it up.

When you go into the Earmaster settings the MIDI drop down selection for sound is empty.

I have Finale 5 running the PC and it picks up a default MIDI Driver, I assumed previously that Finale had added its own. This ...

Regarding no sound in Vista I have a simlar issue.

I have installed Earmaster on Vista 32bit Home Premium and it appears that within Vista there are no default sound Midi Drivers.

An identical PC with XP installed does have Midi drivers and Earmaster works fine.

Reading the Microsoft support ...
