My solution is this:-
Take the whole speech pack you are using and copy it to a new location. Use Wave Edit to adjust the volume of all WAV files to 40% and rename your folder something like "UK Medium Volume". Copy the folder back to Voice directory.
Run MMConfig select Audio Mute tab, tick "alter volume of winamp" set volume to 50% for 4 seconds. Then untick "set volume when giving directions"
In MM change to the new voice pack you have just created.
Voice directions should now be at a comfortable level, and the degree of mute on winamp will mean you don't lose the flow of the music playing.
