Looking at the alsa-info.sh output I can see you're using quite an old kernel.

In order to get better support, I strongly advise you to update to something
more modern. Lots of bugs have been fixed in the kernel since 2.6.35 regarding
which audio controls are exposed through ALSA.

We can only work with the information ALSA supplies us and in this case, there
are no separate controls listed for your external mic.

So the problem here is below PulseAudio and we cannot do much about it.

My only advice, as before, is to please try updating to a recent kernel and
PulseAudio version. I'm afraid that with hardware support, this is your only
option, even if you seemed unwilling before.

I advise trying e.g. a Live CD version initially (no installation) which
includes a recent kernel which may at least allow you to verify that this
problem has indeed been fixed.

As this is not actually a PulseAudio bug (it's in a very old version of ALSA),
I'll close this again here.

Hope this is useful information none the less.
