I just had a similar thing happen to me, with a Delta 66 (also an 
ice1712), after playing with the command-line alsamixer.  I'm driving a 
pair of powered monitors from H/W Out[1,2].

Running envy24control, I found that I had set Master Clock to 88200, where 
I normally keep it at 48000.  In fact, switching between 88200 <-> 48000 
in envy24control produces the pop every time.  The pop is much louder in 
the right (Out2) channel than the left, for some reason I can't explain.

Anyway, if I set it at 48000, I don't get pops when I play audio through 
it ("mplayer -ao alsa1x:ice" [1]), so it seems to be related to changing 
the sample rate, as other people suggested.
