Ah, right, that helps a bit.  Certainly using the controls on either tab has
the effects I'd expect.

I do still have a problem with the ALSA tab though;  when I say many 
duplicated
entries, I mean so many that the mixer is unuseable.  For example, where the
OSS mixer has fifteen discrete sections, the ALSA one has around 140 of them,
including at least thirty called EMU10K1 PCM with three sliders on each, and a
similar number of EMU10K1 PCM Send sections with twelve sliders on each.

I can't believe this to be normal.  It certainly isn't useable.  This is 
why I feel
that some aspect of my sound installation must be hosed.
