Maybe, but only with the Expressgate sound-configuration utilities 
(loaded not from ROM but from a Windoze-installed FAT directory), I 
think, because Windoze (9x/XP/7) can use the mic after selecting the 
right jack.
I have already updated that directory three major versions above the MB CD.

Better than that, I was advised im local LUG to re-install the current 
kernel with:-

sudo apt-get install --reinstall linux-image-$(uname -r)

which has worked a treat to restore the speakers-only condition

No, indeed, I knew that, but was mistaken that it would be easy to undo.
It certainly didn't improve the GUIs inability to select the mic.

Now I need to find the correct module arguments etc to manually edit in 
I'm told that should work, but so far can only find redirecting speaker 
output, not selecting mic jacks.

Anybody done this?
