Ok, I played with this a little more tonight, after a quick compile/test this 
morning before heading to work.

This morning I had the mixer volumes set quite high, a holdover from the 
emu10kx driver for the Audigy Value I'm borrowing for the moment. 

Tonight I sat down for some listening and found that adjusting the mixer 
(using kmix) by one "click" made the buzzing stop, one "click" back up and it 
started again. 

With these mixer settings I get buzzing and can hear my mouse move etc as 
previously described.

[why:~]$ mixer
Mixer vol      is currently set to  54:54
Mixer pcm      is currently set to  65:65
Mixer mic      is currently set to  67:67
Mixer cd       is currently set to   0:0
Mixer rec      is currently set to  74:74
Recording source: mic

With these settings, I don't. Dropping the mic input by one percent stops the 
buzzing. 

[why:~]$ mixer
Mixer vol      is currently set to  54:54
Mixer pcm      is currently set to  65:65
Mixer mic      is currently set to  62:62
Mixer cd       is currently set to   0:0
Mixer rec      is currently set to  74:74
Recording source: mic

Upping  another control by one percent brought it back:

[why:~]$ mixer vol 55
Setting the mixer vol from 54:54 to 55:55.

And dropping it by one percent made it go away.

[why:~]$ mixer vol 44
Setting the mixer vol from 55:55 to 44:44.

It seems like a very binary effect and not just that it's getting 
progressively more quiet until I can't hear it
