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.
