Ok, let me give you a more detailed history of what happens:

  1.  I boot the machine, during boot I manually load module ac97_codec, and
also eepro100 ("soundcore" is compiled into the kernel, although I've run with
that as a module as well).
  2.  I run xawtv and the machine knows to load videodev, i2c-core,
i2c-algo-bit, bttv, tvaudio and tuner.  xawtv pops up a window, I scroll
to channel 3, have to toggle the 'a' button and turn up the sound from 0% to
90% with the '+' button.  At this point, xawtv is working fine, sound and video.
  3.  I kill xawtv and unload all modules that were loaded when the program
ran, ie. those in step 2.
  4.  I load es1371 and then immediately unload es1371.
  5. I then run xawtv again.  Once again all the modules listed in step 2 are
loaded, however this time I only get video and not sound.  I check the mixer and
all lines are un-muted.

I have specifically run through this procedure.  Why does the video sound work
in step 2 but not in step 5, despite the fact that all mixer settings are the
same and I am running the same "module state"??

Ok, thanks.  At least it's good to have an idea of what it is not!  I still
think es1371 must be doing something on loading and not un-doing it on
un-loading, but it's not visable.  Ugh.
