Dear All,
I found a workaround for this - it's a hack but it works.  Assuming you are running pulseaudio (do 'ps -e | grep pulse', if you get a response then you are running pulseaudio) you can use 'pacmd' to set the level.  'man pulseaudio' is also a useful source of information.

So,, type 'pacmd'.  Once inside, 'help' is useful.  'list-sources' will
give you info in the sources, and you probably want to do 'set-source-
volume 1 150000' to turn up the volume on the built-in microphone.
Although I failed to find a configuration file to make this permanent,
the setting is retained when the computer re-boots.  The only thing to
avoid is using the pulseaudio volume control as that will set you back
where you started.

An alternative as suggested above is to remove pulse audio, and the
gentle method suggested above seems sensible.  I took the brutal route
of using synaptic to remove everything pulse related, and so far it
seems OK.  The downside is that you are then faced with a plethora of
options and they have to be right!  The gnome-volume-control seems to me
a bit faulty - the text alamixer is strange but more dependable.  If you
set the levels on 'capture' and 'digital' to max, and 'digital input
source' to 'digital mic', you will probably be in business.
